Are these new or re-furbished batteries?

These batteries are brand new, and with two of them in the pack, it gives you plenty of runtime with all of your tools.

What is the warranty on this 4.0 AH battery

I am wondering if this is lifetime warranty eligible.
Asked by: PH44
Once upon a time, these batteries were "lifetime" warranty which I took advantage of. Today that only applies to batteries purchased in a tool package, as far as I've been told by the Rigid Company. The rub is that I have not seen a "kit" that includes REAL batteries, only ineffective starter batteries. These little batteries do not stand up to heavy usage. That being said, Rigid is a great tool product!

18-Volt Lithium-Ion 4.0Ah Battery Pack (2-Pack) is rated 4.6 out of 5 by 1749.
Rated 4 out of 5 by from As expected Batteries are great. Only thing is I wish they had lifetime warranty like the rest of the ridgid tools.

Rated 4 out of 5 by from 4.0AH Battery Two Pack Works as Expected or Better I bought a two pack of 4.0AH batteries because I knew I would require swap out while working. They appear to carry the heavy 18V GEN5X Brushless 4-Mode Impact Wrench quite well though sometimes they appear to get over-loaded and the tool drops out. About 5 seconds later the tool comes back online just like it never happened and continues to work well until the batteries are depleted. Love the fuel gauge on the batteries. I use the impact wrench and the batteries hard in a heavy duty automotive shop though rarely do I have to charge either battery more than once a day, sometimes less. Good overall performance from these batteries. Wait until they are at a reduced price and jump in and get them!

The impact driver received heavy usage the first couple of years. Now it’s only 15 or 20 screws a day 5 days a week. They are still going strong except for the batteries. They burn out every couple of years with a lot of use. The warranty registration is hard to fulfill. My brother purchased the set online from Home Depot and they said it was an invalid purchase so they had to make a phone call to ridgid to complain. I purchased an extra kit that came with a third battery free and I registered online and was notified 30 days before the registration deadline that one of my batteries was an invalid purchase. Send in the registration by mail with a receipt and we will notify you by mail in 30 to 60 days. I just returned the two week used set back to Home Depot for a full refund. I still have my old set but going to buy another set when on sale just for the batteries and the warranty. My first set I did not register them so no warranty. Bottom line; don’t buy the batteries separately because they only warranty them for three years. Buy the kit even though the batteries need to be recharged every 30 minutes if you use it constantly. I only gave it four stars because the customer Service Department try’s every trick to invalidate your registration so you don’t get a warranty.

I bought this grinder because I watched a video on you Tube about removing thin set from plywood after tiles were removed. I also purchased a dust shield from home depot and a 4 and 5 inch diamond cup grinding wheel. The 5inch worked better. WOW it worked great. Hardly any dust. It ate through the batteries pretty quick though. I was using two (4ah) batteries. I bought two more 4ah batteries online so waiting for recharging was not a problem. I suppose you could use the ridgid corded grinder but the portability of this18v is so handy and manageable . Again I have to say WOW.

Unfortunately when I went to pick it up my combo set at Home Depot, opening the box the batteries were missing. Homedepot gave me a choice, A credit for the price of the batteries or the battery pack . I chose the credit. And after owning my toolset for a bit, I wish I would’ve kept the bonus batteries . Nevertheless Ridgid Tools are great. I will Eventually buy a pair of these Batteries.

Like others have said in the reviews and Q&A NO LSA on batteries without a tool. I also just bought into the Ridgid 18 volt platform thinking I would get LSA on everything. This is misleading at best. I know I should have done more homework but this is not a good way to treat customers. Will I keep buying ? Yes I am in the platform now to the tune of 500.00 +. But I will be sure to tell others about this scam. Ridgid and Home Depot if you read these things please change your marketing.

Rated 5 out of 5 by from I have 4 rigid drills with the standard 18v batteries... I have 4 rigid drills with the standard 18v batteries and over time they have lost their ability to hold a charge under heavy use, so I was using a corded drill to build a wood deck in the backyard. When these arrived, I charged them then put them in my old drills....I completed the deck with just one battery charge (about 1 third)! I'm going to replace all my current batteries with these!

I was impressed with how much I could get done with that size battery. So purchased 2 of the 2 pack 4.0ah batteries which I just happened to find on sale. Now have a battery for every tool plus a spare. Very pleased with Rigid tools.
