Battery Chargers

What motorist doesn't know it? Time is pressing early in the morning and the vehicle won't start. It quickly becomes clear - the battery is flat. Situations like this don't always happen at home, where a neighbour can jump-start the car, which is why owning a battery charger is so important. Be prepared and equip yourself with a high-quality Offgridtec battery charger so that you won't be left stranded in an emergency.

What is a solar battery charger?

Battery chargers can serve as a jump start when a battery stops starting. If, for example, a vehicle is not in use for a long time, only very short journeys are made with it or it is exposed to very cold temperatures, the battery can discharge - jump start. This is where the battery charger comes into play. The advantage: You can recharge the battery yourself and do not have to wait for help from a friend or the roadside assistance service.

In general, older batteries or those that have already been deeply discharged are more susceptible to failure. With regular charging, you prevent this and thus extend the life of the battery.

Which solar battery charger is the right one?

When buying a battery charger, you should make sure that not every charger has to be compatible with every battery. When choosing, make sure that the charger and battery have the same voltage. So if you want to charge a 12V solar battery, you need a 12V battery charger. In addition, the charging power (in ampere hours) must match the respective battery size. In addition, the charging voltage and charging current must correspond to the prescribed value during the entire charging cycle (charging characteristic curve) and the charging specifications of the battery manufacturer must be complied with.

  1. How do I connect a battery charger? First disconnect the connections at the negative terminal (black) and then at the positive terminal (red) to disconnect the battery from the circuit. Now connect the red cable of the charger to the positive terminal and the black cable to the negative terminal. Now you can turn on the charger.
  2. Which battery charger do I need? It is important that the voltage (V) matches the battery. In addition, charging power (Ah) must match the battery size.
  3. How long can a car stand without breaking down? That depends on the condition of the battery. While cars with older batteries could have problems after just one week, well-maintained new cars are quite capable of standing for up to three months without any problems.
  4. How long does a car battery need to charge with charger? It usually takes 10-12 hours to fully charge a car battery.
