Customer Questions & Answers

Are the Ridgid batteries still warrantied for life?

I bought battery awhile back. It went bad and Home Depot replaced it with battery that says "90 day guarantee"! What's up? Do I still have a "Life time Guarantee"? Are any batteries bought now only guaranteed for 90 days?
Asked by: Anonymous
This battery is not eligible for LSA. It has a three year warranty with Ridgid after you register it online.

Will this battery work with Rigid charger # R840091?

Asked by: Anonymous
I'm sorry but I'm not sure of that charger #R840091 . My older Ridgid charger # is BD0745 that I've had for about ten-years and it works just fine with this new Battery .

what is the warranty on the battery? If registered do I get the lifetime replacement warranty?

Asked by: Anonymous
Most brands offer one year plus store option to buy extended warranty. Rigid offers the standard one year warranty and the lifetime battery replacment warranty. This is only offered through Home Depot as a promotion item. You will have to send the proof of purchase, the original reciept (so make copies or get home Depot to make you a copy) plus you will have to register the product on the Rigid website. It is time sensitive so make sure you register it within the timeline. I know from experience.

18-Volt X4 Hyper Lithium-Ion Battery is rated 3.5 out of 5 by 24.
Rated 5 out of 5 by from Home Depot Now Offers Battery Exchange!!! YOU ARE NOW ABLE TO TAKE YOUR BATTERIES TO HOME DEPOT FOR AN EXCHANGE UNDER THE LSA. IF THEY DON'T HAVE YOUR REPLACEMENT IN STOCK, RIDGID WILL DROP SHIP A NEW ONE TO YOUR HOUSE! So I bought a drill with two batteries, one skinny & one fat (1,400mAh & 3,000 mAh, respectively). They both went bad after about two years of intermediate use, but that's no surprise. I took them to the service center and waited 6 weeks for the new ones. I received a follow up call from Ridgid to ask if i was happy with the service center; I said sure, except I waited 6 weeks for them. The representative responded, we shipped your replacement batteries to the repair center 5 days after you dropped them off. In short, it took me calling the service center 5x before they found it. When I was 'discussing' the situation, the representative said Ridgid and HD now allow you to do the exchange IN THE STORE. just take it to the tool service / rentals desk and they will take care of you...no more waiting months to get your batteries back, making the LSA actually worth while!!!!

Rated 1 out of 5 by from I thought Ridgid stood for better quality than DeWalt but I was wrong Bought a Ridgid combo 18 Volt Drill and Impact set with charger and two batteries, one has failed, will not take a charge. These batteries are way costly, to buy a replacement, should have stayed with DeWalt, they stand behind quality. Totally disappointing.

Rated 1 out of 5 by from Second double failure I originally purchased a combo kit just to use at home due to the lower price . I won't mention the normal brand the I use but I'll simply say that I've gone through a total of four of rigid a lithium batteries. My normal brand has been beat up and used many times as long with no failures yet. The first rigid failure, I was lucky enough to run into a rep at HD and he gave me a free( by mail) third battery if I bought two. All these brands do the same basic function but some have more frequent failures. Almost forgot I was told that my last two were still under the warranty period now I only need a receipt!!!@? Thanks rigid Chiller Wayne UA local 250

Rated 1 out of 5 by from died for no reason...replacement very costly. couple years old and seldom used...just decided not to take a charge. push button and one light comes on just to tease you. this is a known issue...lots of complaints online. Rigid does not seem to care

Rated 4 out of 5 by from dont waste your money on a spare battery No warranty on battery only! MY BAD I made the mistake of thinking that because they were offering a lifetime warranty on the tool and the battery, that batteries only would have the same warranty. I just wasted my money on a spare battery that I didn't need. they will warranty the battery that came with the tool unlimited times. SO YOU LEARN

Rated 1 out of 5 by from lifetime my butt. This battery seemed great for a short time. After a few months would only run down 1/4 of the way, I thought it was a fluke until it happened to a second battery. Then it happened to a third and about 7 months of not a lot of use they would not charge at all. I made the mistake of not registering the tools and was told since they were more than 30 days old there was nothing they could do. I love the tools, all of my Ridgid tools but the batteries in my opinion are junk. Wish they would just replace them with new, they say lifetime. If they would stand behind them like other brands they are the only brand I would buy. I have about 40+ battery tools and 6 different brands and for the tools themselves they are the best all around but the batteries themselves are junk.

Rated 3 out of 5 by from waranty to short I was disapointed with only 3 year waranty. I buy Ridgid tools because they boast lifetime waranty. my other cordless kit has lifetime waranty on batteries because I had to buy this one seperate it only came with 3 year waranty.

Rated 4 out of 5 by from Battery warranty The batteries are lifetime warranty, some reviews say that they don't but the warranty that I received Does say lifetime warranty on the batteries. I went to the HD in my area and the sales rep from Ridged was there and he also mentioned that the batteries do come with lifetime warranties.
