CUSTOMER REVIEWS

Rated 3.4 out of 5 by 19 reviewers.
Rated 2.0 out of 5.0 by These batteries are hit or miss as far as battery life span I have purchased a fair amount of Ridgid tools the last few years, and the quality of the actual tool is always impressive, but these batteries are really hit or miss as far as their life span. Of approximately 12 of this battery version/model, I have had 5 be defective right out of the box and another 3 die within two months. The other 4 are still working but who knows for how long but I noticed at least one needs frequent recharging. The warranty does me no good as the Ridgid repair center is not near me and the cost of gas and bridge tolls to drop off and pick up the replacement is not worth it. I have returned the ones that were defective right out of the box but took my oney back rather than replacement. Honestly, I want a warranty I don’t need to rely on, not one I am going to use all the time. If you read other ridgid cordless tool reviews there is always a few reviewers addressing battery issues usually fomr the people that have owned the tool for any length of time. Now to be fair, I have purchased severl of the larger capacity Ridgid Li Ion batteries and have used them with no issues for over a year. So, for me the issue seems to be with these smaller capacity batteries. But after these batteries do their tour I am switching back to dewalt. March 16, 2012
Rated 1.0 out of 5.0 by Expensive with a very very short life span. I bought a Rigid drill and used it flawlessly for about four weeks. The drill was equipped with 18v Li-Ion batteries and "autoshift". After the four weeks the Autoshift started acting up and not providing enough power to drive screws or drill. Shortly after the trigger started getting less and less sensitive until it was just on or off with no control on speed and power. I digress, the batteries only held a charge for about 45 minutes whether using them or not and after a few months wouldn't hold a charge at all. Now I've got two really nice and durable paper weights and a drill with no batteries. Upon looking to replace them through the warranty I was given the run-around and basically told I should just buy a new drill. So I shall, and this time it will be a DeWalt. August 21, 2012
Rated 1.0 out of 5.0 by Batt Life Not very good life span. First ones replaced after one year. Now 2 years old and these are going bad. Now $ out of my pocket. $70 I can see this is going to get old fast. Would I recommend? What are other Lithium batt are better?? June 17, 2012
Rated 1.0 out of 5.0 by Poor product quality and dependability One of if not the worst product I've ever purchased. Like so many others, I kept my batteries inside during the winter and not in the "trades" used only for around the house projects. They (both batteries) just quit working. Contacted Ridgid and got the brush off. They couldn't have cared less that I was unhappy. Buyer BEWARE! December 4, 2012
Rated 2.0 out of 5.0 by Don't BUY! Battery problems!! I have purchased 5 of these over the last several years. Every single one has battery issues! They are junk! Buy Dewalt and save your self the headache! September 1, 2013
Rated 3.0 out of 5.0 by Wish Rigid would make it right I like Rigid tools and it is normally my go to brand. These batteries are the weakness in there lineup. I wish they went with the lifetime warranty instead of the three year and if you do get them serviced I wish they would replaced them with a battery with the problem fixed instead of another battery that will do the same thing in a year. I have already taken three of these batteries in for replacement because over time they just stop working. It would be one thing if I was hard on my tools but i take good care of them and keep all my batteries inside so they don't get cold. Also when you do take these in to get them replaced it takes 3 months to get it back which is crazy. I just wish Rigid would admit these batteries have a problem and replace them with something better when they fail. November 20, 2012
Rated 2.0 out of 5.0 by When they are good they are good. If the Combo didn't have a lifetime warranty I would throw it away. One of the Batteries lasted less than six months. The Stores did not carry the batteries. The stores could not check the batteries to see if they were bad so they had to send them to another store. This process took over 6 weeks before the store called me and said they had my new batteries. Thank goodness for Customer Service in Atlanta. December 18, 2012
Rated 5.0 out of 5.0 by RIDGID Does it again. I love this battery, I got it with a compact lithium set of a drill and recip. saw. It lasts forever, I don't have to charge it close to as much as my old ni-cad batteries. Plus it's nice and light. The only thing about it is, that if you exceed the torque of your drill setting, you have to remove the battery, then slide it back in, but it barely happens, and it's an easy fix. Totally worth it.
