Rechargeable 3.7Ah 18V Lithium-Ion Replacement Battery

Behrman: I bought these for my Ryobi and they worked great. I purchased April 2020 and got roughly 3.5 years out of them.

Dr0pZ0n3: Update: seller reached out and quickly resolved the issue. The faulty one was replaced and it's working good now.

I don't really need a pair of these batteries but it's a great price to buy these pair so I bought it.. One was working fine and the other was just totally dead. Contacted their support and was advised to return and get a replacement. Yes, I could do that but it's just a hustle of returning and I don't really need the other pair so yeah I'll just leave it from here

JOHN W: They are an exact replacement for the 18 V Roybi. drill.
Older technology (as is the Roybe part) so a bit weak as expected
Don't stay charged longer than a week or 2.
No problem. at this price just buy extras & charge before use.

Alex: Pros:

1) easily works in my Ryobi devices. It's a great fit in my trimmer and drill.

2)Great price. I can afford a bunch of these for the same price as an OEM battery. That's useful, I can always have one charging.

Cons:

1) Most worryingly, it didn't seem to interface with my OEM Ryobi charger. I don't know if it's a fit issue, or there's some kind of proprietary chip in the one+ batteries but I couldn't get it to charge. After debating whether to throw good money after bad, I bought an aftermarket charger for these. Altogether still cost me less than a second Ryobi battery would have though.

2) it's not as powerful. These last me maybe half as long in the trimmer, and "peak power" at full throttle is iffy. I think this is somehow related to the maximum discharge rate of the battery. It will cut fine for a few minutes and then seem to lose power. If I let it rest and cool off for a minute or so it will go back to full power.

Very strange.

Overall, they do what I need them to which is to be a backup to help me finish up whatever I was working on when my other battery died.

Paul K.: Since the writing of the original review, the seller sent me (2) new batteries, and specifically asked me to make sure they worked correctly. I have actually got several e-mails from them to make sure I was satisfied. I am. The new batteries are fine, they refunded my money, and I did not have to send the old batteries back. They get points all the way around. And not an American company, they followed though with what they said they were going to do! I changed my original (1) star to a (5), I hope they treat everyone this good...
Charged both batteries. Literally cut about 6" of wood with saw before battery went dead. Switched batteries, made it another 5-6" in 1/2" plywood before battery went dead. Wait for first battery to charge, did it again. WORTHLESS! And just outside of the return window, so can NOT return them! Sad way to do business...
