    About this item

    The Diehard 75/12/2 Amp Fully Automatic Battery Charger makes it easy to charge 12 volt batteries. This money-saving device can be used to charge lawnmower batteries, farm equipment, motorcycles and even small cars and some SUVs. The 12 volt battery charger has two modes; a 12-amp fast charge mode and a 2-amp trickle charge mode. The 12-amp fast charge will charge most batteries in just 2-5 hours; the 2-amp trickle will charge a small 12 volt battery in about 2-12 hours. The portable battery charger is built tough, just like Diehard batteries. The Diehard battery charger with emergency engine start is fabricated using solid-state circuitry with silicon diodes. It has a simple, intuitive interface with LEDs that indicate when the charging process is completed. The charger comes in a tough, durable, rust-proof polypropylene case with a top-mounted handle for easy carrying.

    It will charge a completely dead battery

    It will charge a completely dead battery unlike most smart chargers and do it quickly. For a dead battery start out on the 12 amp setting then reset to the 2 amp setting when the charger begins to cycle on and off the 12 amp setting. Allow the charger to remain on the 2 amp setting until fully charged. Charging the battery completely helps to both save the alternator and the possibility of getting stranded later Nice metal case, heavy clamps and analog type meter all are a plus on this charger.

    Customer review by OSDCrusher

    I bought this battery charger to use with my 1988 K5 Blazer because it sits in the garage sometimes for prolonged periods of time. I also bought it incase the battery fails to start the truck, which hasn't happened yet. I've only used it to charge the battery for a few minutes 2 or 3 times and it's worked great so far.

    Customer review by VillageIdiot

    4.0 stars by VillageIdiot

    The charger works just fine, reviving an almost-dead battery, and acting well as a trickle/maintenance charger. I haven't tried the booster/starter function. The only problem was that the packaging was insufficient: it came with a small dent on one side (the casing is metal, not plastic like most at this price). This was not enough for me to be bothered about
