The Battery Tender® Jr. is much more than a trickle charger. It has a brain. It’s lightweight, compact, and fully automatic; very easy to use, especially in small spaces. It will keep your battery fully charged so that it is ready to go when you are!
Perfect for all lead-acid, flooded or sealed maintenance free batteries (AGM and gel cell).
The 12 volt charger has a complete 4-step charging program (Initialization, Bulk Charge, Absorption Mode, Float Mode).
The 6 volt charger has a complete 3-step charging program (Initialization, Bulk Charge, Float Mode).
Automatically switches to float/maintenance voltage after fully charging the battery.
If the battery voltage drops too far under load, full charger output power resumes.
Solid state, two color LED indicates state of charger.
