Schumacher XC12 SpeedCharge 12 Amp Battery Charger

• 12 ampere fast charge charger monitors battery condition and adjusts charge rate downward to prevent battery damage
• For car, light truck, marine, RV, farm equipment, AGM, gel cell and deep-cycle batteries
• 8 ampere medium charge has a self-adjusting charge rate for everyday charging needs and keeping your battery in peak condition
• 2 ampere slow charge for charging and maintaining small batteries
• The charger automatically determines whether the connected battery is a 6 volt battery or a 12 volt battery

So I bought this because 1) it could do 6V and 12V and 2) it had a digital display for voltage and percent charge. It chooses automatically between 6 and 12V fine. The display however, seems quite off. The voltage is ~0.2V off vs a multimeter, but to be fair the resolution is only 0.1V so its hard to say exactly how off it is. The percent charge, which I was most interested in, appears way off. I had a 6V motorcycle battery that sat all winter, read ~3.5V before charging. I hooked it up, on the slow trickle charge setting recommended for small batteries, and it read 90% state of charge to begin. The SOC rose quickly to the high 90's, where it sat for quite awhile until fully charged. I understand there are a lot of battery types and sizes out there, so this may be hard to calculate, but I thought everyone should have a proper expectation about it. I like to monitor this type of information, which is why I elected for this model with SOC display (I didn't really need the 12A). Now I wish I would've just went with a more basic model.

Other Good:

It does kick out automatically to a maintenance mode once fully charged, and automatically start charging after a power loss.

Other Bad:

The fan is loud, and there is no on/off switch (you must unplug it). Also, while charging, the display switches between the SOC and the voltage setting(6 or 12). It would be more helpful to see an actual real-time voltage instead of what setting it is on. To check voltage status with the unit, you must abort charging and put into testing mode, then go back to charging.

fairly fragile construction. but worst thing was that it failed to charge at the 2 amp setting after only a few days.

This charger is fully automatic and will charge and maintain all types of 12 volt batteries. It also has a small footprint to fit into tight spaces. The only con is that it is rather noisy at times.
