Review on ⚡ MBC010 Automotive Trickle Battery Charger & Maintainer 12V 1A - Smart Automatic Charger for Car Motorcycle Boat Lawn Mower - Suitable for SLA, ATV, Wet, Agm, Gel Cell Lead Acid Batteries by Erick Bowers

Impressive battery maintenance tool for size, price and reliability. Works exactly as specified by the manufacturer. I've had it for a few months now and it works perfectly. For those considering purchasing, please note that this is not a charger. It puts out just over an amp per hour, so it takes a long time, even days, to fully charge the battery. I use it on my off-road equipped Grand Cherokee and drive it once or twice a month. When the indicator is red, it is charging, and when it is almost fully charged, the green indicator flashes. Then when it is fully charged, the green light will be on constantly. It's very sensitive at determining battery needs: when you open the door and the interior light comes on, it flashes green briefly, then turns green again after about a minute. Fiction!
