Mountable Automatic 6- and 12-Volt Battery Charging

Designed to allow for safe charging of batteries used with RV, street rods, classic cars, motorcycles and snowmobiles, as well as deep-cycle or most other commonly used lead-acid batteries, the Schumacher SE-1-12S-CA Fully Automatic Onboard Battery Charger is a convenient accessory suitable for use with most any vehicle that experiences long storage periods between uses, or requires improved battery performance during cold weather. Light, rugged and compact, its low-profile "onboard" outer design and included mounting hardware allow for easy mounting close to, if not directly on your battery's outer housing. This makes it perfect for use as a dedicated trickle charger, although it can also to mounted away from your vehicle in the case of dedicated, stand-alone charge stations for batteries. Once mounted, with the permanent ring terminal connections made and the AC power cord properly connected to a grounded 120-volt outlet*, the SE-1-12S-CA automatically switches between charge mode and maintain mode as necessary. The charger contains an easy-to-read LED indicators related to battery connection and charge state, and an electronic control circuit which safeguards against overcharging the battery ensuring that your stored battery is safely kept at proper levels and will be ready when you need it.

Additional features include: reverse hook-up protection that keeps power from flowing unless a proper connection exists; a 1.5-amp trickle charge rate; intentionally short battery leads and AC power cord that won't get tangled in moving engine parts; and a rugged molded plastic outer case.
