Rockwood Battery Maintainer is rated 4.7 out of 5 by 22.
Rated 5 out of 5 by from Great Battery Maintainer Price was better than the last two maintainers I bought. Works fine I like the long cord. was a little alarmed when the green LED flashed all day on my Dodge pickup, but seemed to work fine on the 4 wheeler.

Rated 5 out of 5 by from Great product for any 12 V batteries I have very good luck with these maintainers. They work on my motorcycles, Lawnmowers, and Wave Runner. (Lasts longer than the HD maintainers I have bought for my bikes)

When the battery has come up to a full charge, does the microprocessor switch over to a pulsating 'desulfating' circuit or does your charger/maintainer simply lower the rate of charge output to prevent boil over?

Asked by: Bman
When in Maintenance Mode : The Charger/Maintainer will automatically shut off at full battery charge and go into a Storage/Float mode with automatic On-Off monitoring. If the battery voltage falls below 12.8 volts, the Charger will re-activate and start the Charging Mode.

Will this charger work on an AGM battery like an Optima?  Thanks

Asked by: K Fish
Use the Battery Charger/Maintainer for charging and maintaining 12-volt regular, deep-cycle, sealed Lead-Acid, Gel-cell and AGM (absorbed glass mat) batteries only
