The battery that came with my mower was defective

Ego support replaced the battery and it has entirely changed my view of the mower. This is exactly what I was hoping for with a new mower. No more planning around breaks every 10 to 15 minutes. With this new battery, I can easily mow my entire lawn without issue. The new battery has restored my faith in the entire EGO brand.

Improvement over our old one.

We were having charging problems with our six year old battery and decided to get a new one. Over several cycles it's proven to be reliable and long-lasting, and the gauge is very accurate and useful in judging longevity. The only downside is price, but I was scared off cheaper knockoffs by the potential for fire.
