Rated 5 out of 5 by Great battery I can't understand the few complaints there are with this battery, I've had two of them now for 3 years and they're both going strong. I did follow the directions, I find this usually helps! Also note these batteries are Lithium-ion batteries, they DO NOT need to be fully charged and fully discharged before being fully charged again because they do not have a memory like the old nickel-cadmium batteries, thus you can recharge the battery anytime you want regardless of rate of discharge.. You do need to fully charge the battery when you first get the battery. Based on what I heard from a battery company, I did for the first time fully recharge and fully discharged 3 times before treating it however I want. Ridgid does not mention this in their operating instructions so someone could e-mail them directly and find out more about this, but since it is Li-ion it won't hurt it either to cycle the battery fully the first 3 times.

Rated 1 out of 5 by Batteries don't last We have replaced four batteries because they don't last. they lose their charge quickly or don't have the ability to recharge within two years. Yes, they are continually charged and maintained. Under the same environment and treatment, my old Craftsman battery has lasted for seven years. Remember to register your battery for either the Three year or Lifetime warranty depending on what size it is. These batteries are not dependable although the Tools have been a pleasure to use and have lasted quiet well. I can't endorse a product that continues to push subpar batteries which are the money maker. Home Depot was helpful to assist with the batteries that have been under the warranty, but that takes time to receive in the mail. December 3, 2014
Rated 4 out of 5 by works good I like that this battery holds it charge even in the cold weather where the older ones always need to be charged again in the morning. November 25, 2014
Rated 2 out of 5 by 119 dollar battery do not last! have this drill with the 4 amp battery and use very little. Used it to attach to my ice auger. Was fine last year (drilled maybe 10 holes) no problem. This year 3 holes battery goes dead. Take home to charge, charger says battery toast. There may be an hour on the battery total since I bought it. No support, no info on battery. Website seems very vague with anything to do with the batteries. Most expensive out there.

Rated 1 out of 5 by Does not fit all chargers The packaging and everything online says this battery fits ALL ridgid lithium ion chargers. Unfortunately that's not the case. We have an older model that has worked with all batteries we have (which are mostly not working anymore), but unlike what ridgid says, this battery will not fit. January 28, 2014
Rated 4 out of 5 by Great too have but bad to charge It's what it is a powerful battery. Gives great life it really brings your tool to life. But the big downfall is that it takes too long to charge. You should know . You have a drill and a sawsall going using both all day. Your going to go through some batteries. If it spend more time on the charger. It does me no good!!!!! maybe hold the prints down. It and all ridgid batteries could use a faster charge. BUT ALL IN ALL GREAT PRODUCT!!!!! Just buy a extra.. November 30, 2013

Answer: 
All RIDGID 18V platform tools and batteries are interchangeable. However, RIDGID 18V Lithium Ion batteries do require their correct charger.
