Review: Great Battery! - The battery was a replacement for my old battery which was the same Earthwise company battery. My old one lasted a long time and the new one is larger so I think it will even last longer.
Review: Doesnt work - I bought the snowthrower and this extra battery last season, charged both but only needed the original. This season the original died after extended use, so I put in the extra. I could make 2 passes then the machine stops. I take the battery out and put it back in and again it works for a single pass then the machine stops. The battery must not fit properly. The original battery has zero issues, so it isnt the machine
