The battery packs are made with 5 x 18650 1300mah batteries in series. The batteries seem to be of good quality and the pack is well made. Overall it's a great value that works well with the Primecables' 20v power tools. The fact that they are lithium means no memory problems and if you don't abuse them , these batteries could last years. Don't run them hot, don't store them fully charged, fully charge just before you need them and don't full drain them and you can extend their lives significantly.

I bought this as the battery on my four year old air compressor is on its last legs. I charged it and it worked fine. I like the fact that the battery is interchangeable with some of the other items sold by Prime Cables. Delivery was quick and timely as usual. Thank you Prime cables

Does its job. Not cheap, considering the price of the tool with a battery, but probably worth it. Certainly better than waiting for the single battery (that came with the tool) to recharge.

battery is no good, it shows fullcharge but dead when put in drill.

It was a good battery but unfortunately it didn't fit what I had ordered it for so I Gave it to my neighbour and it did fit one of his power tools.

The battery I got is not working. How come this product was not tested before. :( Sad.
