Review: Works great! - I was a little concerned about this as the reviews weren't all positive. However the battery works perfectly! It arrived at 50% charge, and I set it up immediately. It charged to 100% in no time! It's working brilliantly! So much better than my old battery.
Review: After 6 months is not working anymore - I bought it in September 2024, it's March 2025, the battery didn't charge anymore. So 6 months is the battery life in my case
