The 5a charger is more suitable for batteries up to capacity 100a. **Q: Is this charger compatible with all motorcycle lithium ion batteries? have a electhium battery for my re himalayan and a motoblatt for my guzzi.** A: It will be ok for the Himalayan battery, but not for the Motobatt battery as I believe that this is a lead acid battery, hope this may help. **Q: Does this come with a molded uk mains power plug? the pictures show an american plug.** A: Yes - it did for mains UK power, plus various battery connections too ## Customer Reviews ### ⭐⭐⭐⭐⭐ Saved a dead bike battery *by S***N on 20 May 2023* Seems smart, considering user input is 'on or off'.
