The DieHard 71219 Portable Battery Charger comes built with a nifty LED indicator that will flash to alert you if clamps are reversed. This causes the charger to not operate, saving you from damage and possible damage to the unit or your battery. Unfortunately, these clamps are a little on the small side. For something bigger and more durable, consider the Ampeak Battery Charger Maintainer Automatic. The DieHard 71219 Battery Charger also comes with three connections options giving you much more versatility.


Accessories included with the DieHard 71219 Battery Charger include 50 amp battery clamps, a 12V accessory plug, and permanent ring connectors for efficient charging. It’s also backed by a three year warranty which is awesome considering most warranties last only two years. It even has Reverse Polarity Protection too! It also comes in a variety of sizes for whatever you need: 2 Amp, 3 Amp, 6 Amp, and 10 Amp. If a budget battery charger is more of what you’re after, consider the MOTOPOWER MP00205A Automatic Battery Maintainer.

DieHard 71219 Battery Charger Maintainer Wrap Up

The DieHard 71219 Battery Charger Maintainer is a fantastic option for those who want a battery charger that does its job without a lot of fuss. In fact, the only fuss it will kick up is if the clamps are reversed, and even then it’s just a flashing light. The clamps are a little small, but that’s not a big issue for those of you who know what you’re doing. To protect your charger and battery from elements and corrosion, use a case like the one described in our Curt breakaway case review.
