## Customer Reviews

### ⭐⭐⭐⭐⭐ Optimate battery charger
*by C***2 on December 14, 2025*

Everything went smoothly and the product works like it should! Thanks, highly recommended!

### ⭐⭐⭐⭐⭐ Extend battery life
*by G***R on February 1, 2026*

Works as described

### ⭐⭐⭐⭐⭐ Plug and play. No need or options to select complicated options for battery type etc.
*by M***L on June 27, 2020*

Arrived earlier than expected. Literally a simple plug and play into my motorcycle that the dealer installed an accessory plug in wire adapter that had a Optimate1.com sticker on it. Looked it up, read the great reviews about extending battery life for motorcycles and plugged it in and it simply did tge rest on it’s own. There are colored LED light indicators that tell you if battery is low, charging or full. When all lights are green you know it’s full and Optimate 1 will maintain the full charge. Wish everything I order for my bike was this simple. Great value for price too.
