GPK Systems Battery for Ryobi Tek4 Ap4001 Lithium Battery Ap 4001

I purchased this battery for my small hand drill/driver in mid January, have used it about six times, charged as required, today April 4 it died!!! won't take a charge, won't do anything.GPK systems should replace it, but I am past the return date? $13+ is not a lot to pay for a battery, I agree, but two months??? it would have been cheaper to rig up bunch of Duracells!GPK, you have lost a customer!!!

Not a good item. I could only use it once! It only charged one and I had to return it for a refund. It was best to buy original at the local hardware store which sold for the same price as 3rd party item.

Excellent batteries! Perhaps better than OEM.

Good batteries as expected.

Charger sucks ass..... Only charges when it wants to... sometimes you have to try different outlets then it only charges for a few minutes.... I use this for my home inspection business... So I know what I am talking about.. Guess I will have take it back to Home Depot.... REALLY

Worked for a couple of charges and then died. Can't charge it via stock Ryobi charger any more.

very good
