Mountable Automatic 12-Volt Battery Charging

Designed to allow for safe charging of batteries used with RV, street rods, classic cars, mototcycles and snowmobiles, as well as deep-cycle or most other commonly used lead-acid batteries, the Schumacher SE-1-12S 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 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.

This review is from: Schumacher SE-1-12S Fully Automatic Onboard Battery Charger - 1.5 Amps (Misc.)

I am fortunate enough to maintain two houses - one in the mid-West for the summer and a second one in the Palm Springs area for the winter. Rather than drive 1500 miles each way I have a couple of cars in each location so each set will sit idle for six months of the year which means I usually have two dead batteries when I arrive for the season. I tried a cheaper brand of trickle charger in the desert last year and it worked but I was afraid that if it burned out I would still return to dead batteries. I really like the quality of the Schumacher products having two of their multifunction battery chargers that have worked well for over 10 years. When I saw that they offered high quality trickle chargers I bought two of them to make the switch to worry free charging. The chargers are well built and heavy for their size and the build quality is typical Schumacher. The chargers are intended to be installed in the engine compartment with battery connections that are permanently connected to the charger and for power a short plug comes out of the side of the unit and is easily connected to a grounded extension cord. I really didn't want to install these under the hood even though they supply the mounting brackets and screws required but I did like the idea of the permanent connection to the battery as opposed to a clamp which could fall off in the middle of the season and leave me with a dead battery. Remembering how the chargers connected in the Power Wheels toys my sons had several years ago, I was able to find polarity keyed plug connectors in the trailer wiring section of the local auto parts store and now have a short pigtail permanently connected to the battery and the ability to plug and unplug it into the charger when I want. Now I have the best of all worlds, the security of a solid connection to the battery and the flexibility of being able to plug and unplug the charger with ease. I like this a lot.

This review is from: Schumacher SE-1-12S Fully Automatic Onboard Battery Charger - 1.5 Amps (Misc.)

I installed this in one of my SUV's that is not driven for weeks at a time.

The Schumacher unit keeps a perfect charge and does not overheat or dry out the battery. The clock, radio, and GPS settings are all preserved and the charger does not seem to draw much power when the battery is charged. I am very satisfied with the operation of the unit.

The installation was a breeze with the included hardware and the instructions were clear and easy.

I do have two small complaints, however:
(1) The battery lugs were way too big for my vehicle and all other cars that I checked.
(2) The AC plug is too short to run anywhere. I wanted the plug to reach to just outside the vehicle's grill, so that the unit could be plugged in without opening the hood. I had to install an extra extension cord for that purpose.

Works great to keep your battery topped off on cold winter nights, and for days of long storage. Instead of dragging out your conventional charger and cables, then putting everything away when finished! Just mount this small unit under your hood, plug in a small AC extension cord, and close the hood. (not affecting alarm operation). It can charge a dead battery (not recommended) but it can take 24 to 36 hours.
