Customer Reviews for RIDGID 18V 4.0 Ah MAX Output Lithium-Ion Battery

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 2 pack set of 4.0 ah lithium ion Max output batteries are much more advanced than the older line on batteries! Couldn't believe the difference until I tried them. They are compatable with all other 18 volt Ridgid tools and chargers. When I do jobs, either around the house or away, I need batteries that will last! That's why 2 of these are perfect! Highly recommend for DIY or professionals.

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.

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.

**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!

Offers significantly more “juice” than the regular batteries. The brushless subcompact impact driver is like a completely new tool with the Max Output battery. That said, the 4.0 battery drains relatively quickly with high-demand tools, including the hand vac, circ saw, etc. I’ll be picking up a 6.0 and possibly an 8.0 to go with it. The 2.0/4.0/6.0 Max Output combo pack for $149 at HD is a phenomenal deal.

Love the power-to-size ratio. Gets the job done without being too bulky on the tool. Love all the options of batteries Ridgid offers. The 4ah is one of my go-to choices for everyday projects.

4ah batteries seem about the best size for a lot of tools. This size doesn't add to much weight to a tool but it will outlast me wanting to hold on to it.

Was a free battery with purchase of drill driver set. Awesome deal

Has the longevity to do the work
