Works but not as well as the 5.0ah. I had to replace the 5.0 after it began leaking. This one isn’t as strong & doesn’t last near as long but it works.
I would recommend this to a friend!

Hi there, Daniel! Thank you for reviewing the BY8705-00. We appreciate you taking the time to review the 2.5ah 40v battery. If you are still needing something that will provide more runtime, we would recommend checking out the BY8708C-01. Thank you for choosing SKIL!

Battery completely failed just after the warranty expired. Called skil and was told I should buy another tool that uses this battery to replace it. Offered no help to replace it but acknowledged it should last 5-6 years and mine only lasted 3.
No, I would not recommend this to a friend.

The operation of the equipment works very good. The Problem is I couldn't finish weed eating and blowing the grass with one battery. So I bought another one. But because my first battery quit working I bought four of them. I didn't want to buy more batteries because of the expense. I purchasing four more batteries that I didn't want to drag a extension cord around anymore. Therefore I was willing to pay the price. (I have a total of six batteries) I can't say the battery last any longer than the very first one. All I know is that I'm pleased with the equipment.

This is the 3rd pwrcore 40 battery that I have bought over the past4 years for my chainsaw. My 2 original ones I purchased in Dec on 2021 and have used them regularly for cutting my firewood and only now has one decided not to recharge. I think getting over 3 years of hard use pretty good.
I have noticed that the batteries don't like cold weather. Normally they are stored in a unheated shed. If I use the saw when it's below 60, it tends to cut only in short spurts. I've discovered if I keep the batteries in the house, then I can do all the cutting I want even below freezing.

It's good but not great. It lasts for 3-4 hours depending on how much you're cutting then it needs to be recharged
I would recommend this to a friend!
