The Smartest Battery Charger in the World
Charges and maintains any 12V car, motorcycle or lawn tractor battery.
If you have a vehicle you don't use every day, just connect our CTEK 3300 battery charger and relax. If the battery is low, the compact unit will recharge it at an optimal rate, varying both current and voltage automatically. When the battery is fully charged, this brainy charger will change over to a maintenance mode to keep your battery in top condition--for longer battery life. Clip onto battery terminals or attach connectors permanently to battery and unplug when not in use. Works for all 12V lead-acid automotive-type batteries (including Optima). |
