Just like your phone or smartwatch, when your car’s battery runs out of charge, it loses power to its electrical systems. That includes everything from the lights to the ignition to the starter motor. In other words, it’s basically useless.
Typically, your car’s alternator should keep your battery topped off, but if and when that system fails (or if your car has been sitting for an extended period of time — say, when you went from commuting to the office to working from home for months — the battery winds up flat. That’s where a battery charger comes in.
The Hulkman Sigma 1 car battery charger and maintainer doesn’t just return your battery to a fully-charged state, but it also helps keep it in tip-top shape. It also happens to be on sale for just $37.99 — a 23% discount from its usual $49 cost.
A great tool to have handy in times of car trouble, the Hulkman Sigma 1 features 1 Amp adaptive charging and five tailored charging modes to charge 99.9 percent of lead-acid batteries. Its nine-step charge optimizer ensures the correct level of power is sent to the battery, no matter what kind of vehicle you’re working with. An impressive 2.7-inch user interface and LED lights will alert you to its current charging stage and status, as well as the temperature during charging. Its durable case is equipped with an internal cooling fan to keep it from overheating.
Not sure if your battery needs repaired or needs replaced? The 360-degree bad battery diagnosis feature can automatically detect battery sulfation and acid stratification and recover the battery and its power if possible.
