Rated 5 out of 5 by from Rockwood battery maintainer. This is the second battery tender from Eastwood, they work excellently at 1/2 the price of the competitors. Would definitely recommend it.

Rated 5 out of 5 by from Small size but great build quality and reliability I bought this battery maintainer a long time ago, around 2014 ~2015, and it is still as good as new, and delivers reliable service. I use it on my wife's Subaru Forester, which is driven infrequently and on short local trips. This maintainer ensures that the battery is always in optimal shape, even during NW New Jersey winters. I came back to Rockwood.com to get another one for my car, but as expected after such a long time, the price is much higher than when I purchased the first unit... Still, it's worth it!

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)

Rated 5 out of 5 by from Real high quaility I got mine within 4 days after order. It works great. I tested the battery after it went to storage green light and it was full charged. The extra permanent attach cable I modified with an auxiliary plug so I could just plug it into the cigarette lighter plug or Aux to charge the battery. Don't have to open the hood.

Questions & Answers

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.
