Optimate 5A Lithium charger TM290
These battery chargers are especially made to charge and maintain Lithium-Ion batteries. Available as an 0.8 Amp charger that works from -20C to +40C and is great to keep your Li-Ion battery in good condition. There is also a 5 Amp charger that works from -40C to +40C and selects the best of its 5 charging programs, based on the condition of the battery and temperature, great when you leave your bike unused for more than just a couple of weeks. Both chargers also maintain the battery by charging and discharging at regular intervals. This will ensure the battery will not get overcharged or lose too much power. Chargers come with one set of cables that can be mounted permanently to your motorcycle and can be plugged in to the charger, as well as a set of cables with battery clips.
