The little charger that works.
This little charger does a lot for the money. It diagnoses (indicated my battery was bad and needed replacing) as well as provides a clear display of battery charge and overall amps while charging (amps count down to zero as it charges). It can charge lead acid as well as ni-cad batteries. It's much lighter than my old battery charger and can also be set for cold cranking when you can't wait for a full charge. I would recommend this charger to a friend.

This is my second unit, opened up first one and just before I plugged it in i heard a slight noise and its a freaking screw inside shaking around. Returned it to Walmart and couldn't exchange it, new policy. Purchased another one, at checkout for 15 minutes but I does the job charging my lipo battery.

I use this charger to occasionally charge a LiFePo 500Ah battery bank during off-peak hours. It's worked reliably, without issue, for about 4 months. Notes to consider: No power switch. The charger turns on when plugged. The default battery type is Lithium when turned on, so this charger is geared more towards lithium batteries. It's fine to briefly have the setting on lithium when you already have the charger hooked to a lead battery, and turn on the plug-in the charger; the only difference is the cutoff voltage. The charge rate is solely automatic and dependant on the state of charge of the battery, you cannot select the charge rate. The maximum charge rate, ~25 amps, is when the battery voltage (in a lithium battery) is below 13 volts. The charger can put out up to 25.6 amps, which is above its listed current rating. At around 25 amps of charging current, the charger draws ~5.09 amps max and 603 VA, and consumes 404 watts, which calculates into a power factor of 0.67 (which is a very inductive load). The conversion efficiency (from AC wattage to DC wattage) is about 86.2%, which is better than Harbor Freight's Viking 15 amp charger at.

Absolutely unusable. has to be plugged into the wall to do anything and the cord is not long enough to run from any outlet to a car outside. i took my battery out of my car to charge it inside only to find you need an additional part to charge it outside of the vehicle. Complete waste of money and time and I'm still stranded
