Powerful 18V Battery for Rigid equipment
There's no doubt these Rigid 18V 6.0 Ah MAX Output LIhiumIon Batteries are among the best out there. The batteries are compatible with all Rigid 18V power tools which makes them work in a lot of situations. Even better, the battery is eligible for the Industry's Best Lifetime Service Agreement. (Details with the battery.) The only downside is this battery will only work with Rigid Power Tools and only those tools that require an 18V battery. If you have other manufacturer's battery operated tools or less than 18V, you are out of luck. And if you do not already own a Rigid battery charger, you will need to purchase one. Avaiable at Home Depot, of course.

MORE POWER!!
I have a whole fleet of 18v ridgid tools. This 6.0ah battery is an awesome upgrade from the standard 2.0 or 4.0. As expected it fits all of the ridgid 18v tools. What was not expected was that the new bigger 6.0AH battery is the exact same size as the 4.0!! Very happy with this item. The battery being the same size as the 4.0 ensures that the tool you attach it to is not made more bulky or harder to use with an oversized battery. This one has what seems to have become standard with the push button life meter. Simply put it into service the same way all others are used..

Great power!
I have several Ridgid tools and this battery is great! It will last you just about all day and only needs about 45 minutes to an hour to recharge. It has 2 levers on either side of the battery, which by squeezing allows you to remove the battery from the tool or the charger. It also has a readout letting you know how much power is left. It also has a lifetime warranty, so you won't have to buy another one when this one wears out. Make sure you register it though!

Battery Only, No Charger
Ordered this battery to go with the Rigid Multi-tool I ordered at the same time. Didn't realize battery didn't include charger. So, after ordering the Rigid Multi-tool and this battery, I have to order a charger to use it. Buyer beware! Battery came with a small charge, so I was able to use it a little in the multi-tool. It fits the tool well, easy to install and remove. Have no idea about charging time since no charger was included. One positive, I think, is that this is included in Rigid's Lifetime Warranty program. Register the purchase and they replace the battery if it quits, supposedly. Never had to use the program since the only Rigid tool I've purchased in the past was returned to the store because it wasn't durable and easy to use.

Amazing amount of power
The Ridgid 18V 6.0 Ah MAX output Li-Ion battery really allows the more power hungry tools, like the reciprocating saw and circular saw, perform like their plug-in counterparts. While this battery is a little heavier than the smaller 2.0 Ah battery, and negligibly heavier than the 4.0 Ah MAX battery, its larger size was not a problem with the larger tools and actually gave a nice balance to both saws. While you can certainly use this battery with the various drill/drivers and other tools, the added size and weight will be noticeable but it's great to have all the extra power if you are drilling larger holes in hard material. The Ridgid batteries have a "fuel" gauge which is very accurate and beneficial. They also carry a life time warranty, which is a nice extra. The battery arrived with only a minimal charge, which isn't a problem unless you wanted to use it as soon as you obtained it, and it charged up as expected using the standard Ridgid 18V charger. If you own, or plan to own, any of the Ridgid saws or other tools that would benefit from more power, this battery will make a great additional to your collection and greatly enhance the operation of those tools.

LIGHTWEIGHT; POWERFUL; LONG RUN-TIME
LIGHTWEIGHT; POWERFUL; LONG RUN-TIME — The RIDGID 18V Lithium-Ion MAX Output 4.0 Ah Battery (2-Pack) are a significant upgrade from my previous Ridgid battery. They are two times more powerful with three times the run time compared to the previous battery. I was impressed with how lightweight they are for batteries with this much power. When using one of these batteries with my Ridgid angle grinder, the increased power was apparent immediately. With the long runtime, there was not a problem completing the task. If there had been, having two charged batteries would have provided me with an incredible run time. The batteries took about 90 minutes to charge so when one battery runs out, the second battery could be used while the first one is being recharged. I am looking forward to the power and the long run time when using my new Ridgid framing nailer. The batteries are made in China.

RIDGID 18V Lithium-Ion MAX Output 4.0 Ah Battery (2-Pack) – I recently got some Ridgid cordless tools and wanted some extra batteries. Of course, I had to buy Ridgid batteries for these tools, but that should be expected. From my experience the performance of Ridgid batteries is comparable to other tool brands. Their cases look and feel well made, they charge pretty quickly with a fast charger and they last about what I expect a 4.0 Ah battery to last in a drill or impact driver regardless of the brand. Ridgid batteries, like other brands include fuel gauges that indicate the power level. The big selling point for Ridgid tools and batteries, after performance, is the Ridgid Lifetime Service Agreement.

This batteries are an exact replacement for the batteries that came with my Rigid 18V tools. Whilst cosmetically they are slightly different (please see my video for a description of these differences) they are functionally identical, This is a value pack, and comes with two batteries in a blister pack Four LED indicators read out the charge level when pressed, and display the charging status when they are in the charger. I had some 1/4 inch concrete anchors to place in concrete and these extra batteries meant I could complete the whole job without needed to recharge a battery mid job.

I got these batteries to power my ½” 18v impact wrench. I have several pieces of equipment that require lots of power and torque to remove rusted nuts and bolts. These 4.0 Ah batteries have more power and last much longer than the 2.0 Ah batteries that came with my impact driver. I was changing two sets of 4 wheels / tires out on my trailer, it was very handy having two batteries to swap out, so didn’t have to stop for charging. They can be used with any other 18v tools for this brand, so I am looking to add more tools because of these batteries. Exceptional batteries

These batteries are amazing. They fit all the various Ridgid power tools 18-volt types. Some that I previous purchased I have had between 5-10 years and still they charge and work great. These new Ridgid 18V Lithium-Ion Max 4-0 Ah batteries are just additional power for my growing Ridgid power tool collection. What is great addition that I am able to recharge these batteries easily from my solar power farm. My sheds are completely assembled by these rechargeable batteries. I am also using them for many projects and they last and last. Very fast recharging as well. I am very satisfied and looking forward to many more years of service from them. You can also register your purchase of this 2-pack and receive a Lifetime Service Agreement. That is how confident this company is about their batteries. Thank you, Ridgid, and Home Depot, for providing your customers the very best in quality. I love and recommend this 2-pack battery pack. I am sure you will love them too!

I regularly use battery power tools by three well known quality tool companies. They all outperform cheap or non-pro quality tools, the kind I had near my workbench and were useless since their batteries wore out in the second year and replacements cost more than the tool. I only buy quality tools now, and if you're thinking about buying these you have decided that Ridgid has given itself an advantage over all the rest by promising free replacement of tool or battery forever. They charge quickly and quietly, are relatively small in size, offer a charge test light, and give the kind of rugged performance you need. The 4 AH is only a bit larger than the 2 AH and saves a lot of time and effort.

These Ridgid 4.0 AH batteries have a lot more 'grunt' than their lower-rated siblings. They arrived just in time, I was running into trouble drilling deep holes with a 1" speed bit into a freshly cut hardwood stump. While it's no shock that a 4.0 AH battery outlasts a 2 AH battery, I was pleasantly surprised to find they were much less susceptible to overheating Plug right in to my existing chargers, and are an exact fit to Ridgid 18v tools. Heavier than the smaller batteries, for sure, but that is pretty much a given. They are approximately the same weight as their Milwaukee 4AH 18v cousins.

RIDGID 18V Lithium-Ion MAX Output 2.0 Ah Battery (2-Pack). This replacement battery set came with two batteries but no charger. They are the standard 18v batteries used in all of the Rigid tools. Each battery has a charge indicator activated by a small pushbutton near the led display. I have never tested the life of the batteries in use but the premise is that there is enough charge to last for two hours of use. An ampere hour or amp hour is a unit of electric charge, having dimensions of electric current multiplied by time, equal to the charge transferred by a steady current of one ampere flowing for one hour, or 3,600 coulombs.

RIDGID 18V Lithium-Ion MAX Output 2.0 Ah Battery (2-Pack) Having spare batteries lets you keep working while the other battery is charging. The batteries are lightweight and work in all my Ridgid tools. They last a lot longer than the 1.5 batteries. I have had these for a week and yet have needed to recharge them. Register within 90 days for lifetime parts and service. They did not come with a charger so I used the one that came with my drills. It is always good to have an extra battery available.

These Ridgid 18Volt Max Output batteries deliver considerably more power to the tool than the original 18 volt batteries I got with the tool set. These batteries need to be charged before initial use and I noticed it takes about an hour longer to charge than the original batteries but they last at least twice as long as the originals. If you are doing heavy duty drilling or impact driving, I highly recommend these batteries and as with many Ridgid tools, they have a Lifetime warranty. These are a great addition to my tool collection!

I recently got a ‘package deal’ on a set of RIGID tools and was so pleased with them, that I had to get a couple backup batteries to get me through my jobs around the shop. When you are building a work bench that’s held together with a lot of pocket holes, you are drilling a lot of holes at an angle, running in a lot of screws, and running in a lot of lag bolts to hold the casters to the bench. The RIGID tools are excellent and now that I have a pair of 4AH batteries, I can go through the work day using my two tools and don’t have to worry about running low on battery power. The 4AH batteries change easily and hold their charge throughout the day. It’s nice to use two cordless tools all day and not have to change batteries. They performed flawlessly all day long.

these batteries make a great addition to your rigid tools, they have a little longer run time than the previous batteries so they will last a little longer than the older version and they supposedly give your tools a little more power when needed while doing the job so not to make the tool work harder. They will make a great back up set of batteries to have and if purchased you can get the rigid lifetime warranty on them if register in the time period.

One of the most frustrating things is when you have been working all day long, and you are just about to finish your project and knock off for the day and you only have a little bit more to do, and your power tool dies! But if you have a pair of these powerful and long-lasting batteries, a quick swap out and you get your project done and get to go home happy! And since you can swap out these super lightweight batteries in multiple Rigid tools, you can be prepared by having a couple of back up batteries to load into the tool of your choice. And now they even come with a lifetime warranty too! They have a power meter on the end, so you can quickly and easily see how much juice they have left in them. At the end of the day, simply pop them in the charger and you are ready to go for the next time!

RIDGID 18V LITHIUM-ION MAX OUTPUT 2.0 AH BATTERY (2-PACK) These batteries are nice they are only two amp hours. They last along time with the drills. The reciprocating saw eats them up if you are doing a lot of sawing. I have a 4.0 ah battery if I need to use it for a lot of cutting or through thick material. I have 3 batteries so i just make sure they are all charged and I don't seem to have any problem. Good strong batteries very happy with them.

The Ridgid 18V Lithium-ion Max Output 2.0 Amp-Hour battery two-pack is a great enhancement for those who already own Ridgid 18V tools and have the battery charger available. These are high-quailty high-output batteries and will fit any Ridgid 18V cordless tool. They give you the ability to just change batteries instead of having to recharge one battery. These are the lightest of the 18V battery series and though they are of lower capacity there is still plenty of run-time when using them. They are perfect when you work overhead and many tools just don't need the bigger packs. I prefer these 2.0 amp packs for most of my Ridgid 18V tools. Each battery has a power gauge to let you know how much juice is left in the pack. That way you can avoid having to make an extra trip back to the truck or shop to get a full one. These batteries are the improved newer high-performance versions and this is a two-pack which saves a little money over buying single batteries. All in all, they perform well and will give you a little more flexibility when using your Ridgid 18V tools. I recommend them.

These two RIDGID 2.0 AH batteries came in handy on a recent window covering installation. I was installing shade brackets, in all the rooms and on all floors, onto the window casings/trim of a house built in 1918. Wood that old, especially when oak, is hard as a rock. Since the brackets were not near an edge I decided to not predrill the holes. Using my RIDGID drill and 1 1/4 inch #8 hex-head screws it required all the low-speed power the drill could provide. I ended up almost fully draining one battery and had to start on the second one. When I first received the battery pack it took about two hours to initially charge the batteries. Recharging seems to be quicker.

The 18 volt line of Ridgid power tools is pretty expansive. That is important for cordless tools, it gives you interoperability with batteries and chargers across all your tools, rather than having a different battery and charger for each. Previously, I did this with the black-and-yellow line of tools, but these Ridgids are a generation newer, just as capable and much lighter weight. You can't have too many tool batteries. These charge pretty quickly, and have a useful charge indicator built-in. They attach solidly to the tool, but pop right off when you need to change.

Great additional batteries if you have several Ridgid tools or want to work continuously. These batteries provide plenty of power for a wide variety of Ridgid tools, are light-weight, and recharge quickly. The batteries have a power level indicator that illuminates when the button is pressed to show a fairly accurate estimate of the remaining charge level. Because they are Li-Ion, they provide the same power output as the charge level drops. The batteries are compatible with all Ridgid 18V chargers so they should work fine with the charger from your existing 18V tools.

SMALLER; LIGHTER; MORE RUN TIME; MORE POWER — The RIDGID 18V Lithium-Ion MAX Output 2.0 Ah Batteries (2-Pack) are a definite improvement over the previous 2.0Ah batteries. They are smaller and weigh less. See the photo. The lower weight will be helpful with whatever tool you are using them in. The primary advantages though are that the runtime and power have been increased. The previous 2.0 Ah battery lasted for only six minutes with the RIDGID shop vac. These should last longer. These batteries took about 30 minutes to charge which is longer than the previous ones did. In my case, these batteries are a useful addition since I have four RIDGID tools but had only one battery. These batteries seem to provide more power when used with my RIDGID hand vac. They are a product of South Korea with additional processing in China.

Ill be using these on my ridgid job site radio to.

Lacks protective rubber molding
**Ridgid, I would like to test and give feedback on your products** The Max Output battery brings power(which is the most important factor in a battery), but has a key downside as well(this one lacks rubber molding). This is a big minus and starts to take a toll on hard plastic of the battery quite fast. For this reason I recommend looking at older generation batteries from ridgid still readily available. Both regular and Octane batteries while Ridgid still carries them. As of 2021 there is a sale on them for 120 dollars you can get 2 Octane 3AH. No matter what battery you get from ridgid follow simple rules to extend its operational life. 1) avoid leaving them out in the sunlight unnecessarily. 2) store them in cool dry place. Manufacturer's guidance is 30%-50% charge for long term storage. Every 6 months "charge battery pack as normal." 3) lithium ion do better if not fully discharged and if not fully charged. Considering their purpose the latter is hard to achieve, but for prior - swap out the battery when its in the 20% of its full charge range. Goodluck!
