Customer has been confirmed to have purchased the item from Walmart.

Only issue I have is the lack of proper shipping material when this was sent to me from the Walmart warehouse. The charger was put in a box twice the size of the charger with no (ZERO) packing material and of course it bounced around quite a bit en route to my home. The first unit was damaged and I had to send it back. After discussing this with Walmart personnell, the replaced unit still came back with zero packing material. I am out of town now and have not had a chance to check it to see if it also is damaged.

The good: Works fine out of the box. Fully automatic, with maintain (float) mode. Has a cool automatic desulfation mode for batteries that haven't been charged for a long time. Good, hefty transformer. The bad: The clips don't open quite wide enough for the clamps on a post-type battery. You can get them on there, but it's a pain. They're tin-plate instead of the traditional copper, not sure how this will hold up. The claim of 30A charging is misleading: operating in 30A mode, it cycles on and off and won't finish much faster than 12A mode (despite claims to the contrary in the manual), so it's really only a 2/12 charger with 100A start.

I have already used this charger several times to get the tractor started, charge a pickup battery that is not used much, and trickle charge and start my car. It is pretty much idiot proof! There's a light to tell it is charging, charged or needs checked. A read out of what percent charge the battery has, and other good features. I can finally quit asking my neighbor for help!

Easy to use charger, just connect to battery terminals and plug the power cord into wall outlet. Select battery type and charge speed and it takes care of the rest. It has a cool desulfation mode that it goes into automatically if it detects a sulfated battery. the charger works with 12V standard, Deep Cycle, AGM Gel Cell batteries or 6V standard batteries. The 100 amp emergency start mode is for use WITH a weak or run down battery in the vehicle. The alligator clips are huge and easy to handle. There is plenty of room to store the cables on the unit. All around a super nice charger for the price.

Customer has been confirmed to have purchased the item from Walmart.

This thing is awesome, it saved me a couple of batteries which my other chargers couldn't even charge. I thinking this one is the best bang for the buck in terms of features because it goes up to 100/30 Amp full blast which will charge up a completely empty battery within an hour or two. However, the healthiest way to charge a battery is on the slow trickle (2Amp) so if you have time, use that one to preserve the longevity of the battery.

  • A. This charger detects when the battery reaches full charge and switches into "Float Mode Monitoring", trickle charging as needed to maintain the battery at full charge. Full details are in the included manual.

  • A. Yes, that's why I bought it, to charge and maintain (trickle charge) the batteries in my RV. The voltage is maintained at the level for they type battery that it is connected to.

  • A. It will not overcharge, it goes to float mode (not trickle) automatically, where it switches on and off and charges just enough to maintain the battery.
