"I've used a number of 12v chargers, but this is the best. I primarily use it to recharge a VMAX 35Ah AGM trolling motor and 8Ah AGM fish finder battery. I sometimes spend 10 hours or more on the water on a pontoon, so I needed the lightest batteries I could get away with, and maximizing their charge is essential. So far, this system has always got me back to the dock with power to spare.
Four green and one red LED lights give info re discharge level at start of charge and real-time charge status (lights also flash if you reverse polarity). When done, it shifts to trickle charge, so battery is always at its peak. Also like that it is small and light compared to other chargers. Standard computer power cord (IEC) connector can be removed, and it easily stores tackle bag.

This review is from: VMAX BC1204 3.3A 4-Stage Automatic Microprocessor Controlled Battery Smart Charger / Maintainer for AGM, GEL, SLA, FLA 12 Volt for Car Solar Marine Trolling Auto Scooter Wheelchair and other 12V Batteries
I own three of them. I also own a BC 1215. I use one BC 1204 to maintain a bank of two Vmax SLR155 solar batteries. I use one BC 1204 to maintain a UPG 12V 100Ah battery and I use one BC 1204 to maintain a Deka Intimidator AGM deep cycle car battery. I use the BC 1215 to charge the bank and the UPG when I deeply discharge them. When they are fully recharged, I put back the BC 1204 on them for maintenance. I'm a happy man. just what was needed, June 2, 2014
"A great float charger and intelligent charger for my deep cycle marine battery.
Lightweight and simple to use and a good price...."
I like this charger/maintainer, June 9, 2015
"I like this charger/maintainer. Simple to use and works well. I use it mainly for my 35AH VMAX battery for my trolling motor but have charged other batteries with it. It gets a little warm towards the end of a charging cycle, but cools right down when battery is fully charged and unit is in maintain mode.
