Excellent. Highly Recommend
Attached the socket to the battery which fits discretely under the scooter seat. If you have an alarm/tracker fitted to the bike and sometimes do not ride for days then these battery top-ups are very important. This product makes the process easy and convenient. Recommended.

A reliable and good value product
Used for last 2mths and working fine. Previous model used for 7yrs, and though it was working fine thought it time to buy the latest model. Used with my motorbike when it's garaged for trickle charging.

Great value
Fantastic! You know exactly what you’re getting. It may not have the features of a more expensive version, but what do you actually need? You plug it in and it maintains your battery. I’m going to buy more for my other bikes now.

Lightweight and easy to use.
This Optimate provides a trickle charge for my lithium battery and does not overcharge or overheat. This is the second optimate I have bought and I would recommend it.
