You can use any newer Blue Max 18v battery. Luckily I haven't had to use it yet. I am blown away on the performance of this saw. I filled the bar oil, and it sat overnight. Both Saws a NOT TO CUT YOUR FIREWOOD!

Blue Max 6595 Final Thoughts
"I am very impressed."
It went though them all rather easily. The chain did indeed have 57 links. Also unwieldy when trying to thin out scrub oak. I think it too was broken or the chain was dull. I don't get all the negative reviews.
