  • Works okay
So bought this battery for my weeder couldn't find the one I had that came with it. This one does work and helps get the job done, (found my other one). Only problem I have found is it doesn't hold the charge as long as the original one does. But for me with the 2 I can get my yard done. Needed 2 anyways to do my whole yard so it does help, but if it was the only one to work with it would have to recharge sooner than the original one. ... show more

  • Doesn't hold a charge
I wish I'd listened to the product reviews. The initial charge didn't take too long and worked beautifully. By the second time, it did not want to hold a charge.
