Great product for maintaining a charge on batteries without overcharging at a reasonable price.
Great charger but better deal is waiting for you
This is a great charger but the same company (schumacher's battery maintainer), makes an identical product for sears, branded as diehard.
It costs the same as on amazon but comes with a 3 year warranty, not the standard 1 yr. warranty found here. Plus you don't have to deal with shipping hassles when you can just go to your local sears and pick one up or exchange if you have problems.
Just what I needed
You've got to love a product that does everything that you want it to do at a fair price. I'm using the SchumacherSEM-1562A to keep a trickle charge on my boat battery. Formerly I had to remove the battery each winter and install it in the spring. To do so meant dismantling part of the boat. This unit solves the problem.
SchumacherSEM-1562A Slow Charge Battery Companion (1.5 Amp) This product is one of the best for maintaining a charge on batteries that go for extended periods of time without being used. Battery failure has been eliminated for me on my generator and storage batteries for my amateur radio equipment. It works great on sealed lead-acid batteries that are now used in a lot of applications.
