Questions & Answers

Lifetime guarantee on these batteries?

Asked by: magnusphi
Looked at the responses ... Unless Ridgid has changed policy in the last couple mo. Battery buy it self . 3 Year Battery bought with tool . Lifetime ... IF >> IF you follow all the rules . ( just bought 2 different kits this fall . All items are covered with lifetime AFTER register on line the ser. numbers . ) There is NO variance on the rules . If you have to exchange a battery for a new on you REREGISTER that REPLACEMENT battery ( in 30 days if I remember ) and if you don't .Then you they will not cover the new replacement even though they have a record from the service handler of the old bat and the new one being exchanged . ( I know I just got it done in 10 -2017 . ) You MUST call in not on line but call in on the phone the NEW serial numbers or they will not be covered . If old bat is ni-cad ... you get Ni Cad replacement . If lithium then you get lithium . The co. that uses the Ridgid name is not for satisfying the customer with the lifetime agreement . It's there as a marketing tool . The service centers are not plentiful . Now with that said . I am on my 3rd set of nicad's - 4 of them . ( this last set would have been $200 if I had to replace them with Lithium ) I followed all the rules and got lucky that the new service center is only 20 min away . Check your area via Ridgid site . If you think you're gonna get Home Depot to service it YOU WON"T . It is what it is ... yes I have saved money . KEEP YOUR RECORDS .... I don't trust them . I have never been lied to . But they are not about keeping the customer happy . It's about selling the product with a promise .. if you jump the hoops . Thanks Duncan Adams

Can this be used as a cut off tool?

I'm wondering if this tool can also be used for cutting applications.
Asked by: Edmund
I have been using the grinder with a thin kerf cut off wheel for removing 1/2" concrete wedge anchor bolts and just recently cut off a tail piece of 1-1/4" sch 40 iron pipe used for stairway hand rails. I Highly recommend the 5AH battery for this tool to get max performance and decent run time.

The add says $99 for the "Pack" yet it also says "each"! Which is correct?

Asked by: gt
I paid $99 for the 2-Pack - which is a great deal.

Is a charger included?

Asked by: Lawles
No charger included. And, according to Ridgid when I registered them for the LSA the batteries are not eligible for the LSA.

18-Volt GEN5X Cordless Brushless 4-1/2 in. Angle Grinder (Tool-Only) with Handle and General Purpose Grinding Wheel is rated 4.4 out of 5 by 486.

I bought one of these grinders to use as a cut off tool with thin cut off wheels. This tool is the worst tool I have ever bought. It has absolutely no power and was a waste of money. I sent it back to have it checked by home depot's tool repair people and they said it was working according to factory specs. It had so little power it would barely cut a regular size lock hasp. Please do not waste your money on this tool. Other rigid tools are ok as I have many of them nut this is a total waste. If there was a lower rating I would give it that.

A week after I got my new Ridgid grinder, I needed to replace an exhaust pipe on my truck. I was excited to use this. I took 3 fully charged batteries with be. Knowing if probably go through then pretty quickly. Well batteries were not the issue. Every 3 or 4 seconds of grinding bolts, the grinder would shut down. I was not able to get anywhere with this thing. I went to the the garage. Grabbed an extension cord and my $12 HF grinder. Then I was able to get the job done. I call this thing a disappointing dud

Worked great until the cheap on/off switch broke off trying to turn it on. Contacted Customer Service earlier today for help, but since I didn't register the unit (6 months old-approx 10 uses) we will see if they will fix it or I have to swap it for another at Home Depot. All my tools are Ridgid tools but the last batch I bought from Home Depot is inferior to the set I bought 12 years ago. FYI to get the warranty you must register online, give the code off your receipt, enter all serials from products (battery, drill, charger, etc) mail them your original receipt and wait for them to verify your purchase. A hassle created to keep people from obtaining the "Lifetime" warranty.

I used (2) Gen5 batteries and proper cutting blade with it as well. It literally took 4 full charges to make the cut. I then grinded down all the sharp edges and it used 1/2 the battery. It did the job but it took 3 hours including charge time to finish the job. Maybe it wasn't meant to cut and just grind but I got 3 minutes run time with it each charge. I don't write many reviews but I don't want to see someone needing a proper grinder and end up losing time on the job because of a similar experience as mine. Just buy a corded one!

Rated 1 out of 5 by from Ridgid Batteries-Purchased 24V R885 Circular Saw with all lifetime warranties for saw, chargers (... Ridgid Batteries-Purchased 24V R885 Circular Saw with all lifetime warranties for saw, chargers (3) and batteries (3). All paperwork done over net and items mailed as requested. Battery dies and I contact Home Depot for replacement. Reply-We see you registered all items, but we don't have a record that all the necessary items were sent to us. Bottom line - no batteries. My guess is they don't make them anymore and they want you to purchase a new product. Meanwhile, my batteries are in a no work or depleted use state. Solution - Dewalt offers trade ins for any working tools. I now own two Dewalt Flexvolt (60 V) units and they blow Ridgid away. I have gotten rid of all but two Ridgid products. NO MORE RIDGID FOR LIFE. I SPREAD THE WORD TO ALL MY CONTRACTORS AND FRIENDS. I think Ridgid took a knee on this one instead of standing with hand on heart and pledging allegiance to its customer.

This is perhaps the only ridgid tool I have ever been disappointed with and I own over 30, my use for it was not exactly the use intended for the tool. I wanted something I could put a circular chain saw blade on to girdle trees. Now I have done this with some of my corded tools and they do it with ease, but this tool kept overloading and stopping. It does cut metal quite well if you don't push it, and seems to grind metal, again if you don't push it.

I recently purchased the 2-pack 18-volt high capacity 4.0AH batteries and have only had them for less than a month one of the batteries will say its fully charged on the charger but once placed on the tool being used it doesn't work and the battery charge indicator says its discharged. I have purchased Ridgid products before and the LSA that comes with the kits are great until you look for a location that does either repairs or exchanges and there are very few to be found in the local area not to mention the LSA (lifetime service agreement) doesn't apply for just battery pack purchase. I plan to contact Home Depot to see if they can be returned for an exchange.
