When purchasing a battery charger there are several factors that you need to consider. For instance, the cell chemistry of the battery and the charger need to match, this means that you can’t use a charger designed for lithium batteries on nickel-based or NiMH batteries. Mixing and matching batteries and chargers can cause irreparable battery damage. You should also ensure that your charger includes protection against overcharging, as well as short circuit and surge protection.

The right battery charger for the right battery

Sustainable.co.za carries a range of Omnitech battery chargers that include charge protection and short circuit, reverse polarity and surge protection as standard. In addition, our battery chargers contain a manual switch that allows them to be used as a either power supply or DC backup system when used in conjunction with batteries. They are also corrosion resistant and have thermal control to ensure that continued safety and long life of your battery.

Battery chargers for lithium batteries, such as those used in cell phones, laptops and electric cars tend to work better if the batteries are not fully discharged. Battery capacity is also maintained if the batteries aren’t fully charged; they degrade more quickly when recharged to only 40% capacity rather than fully recharged. Lead acid batteries, such as those used in conventional cars and vehicles, tend not to suffer from ‘memory effect’ and can be recharged any time, although it’s important to use a battery charger with a chemical composition that matches the battery, otherwise you risk sulfation (damage that results from the degradation of sulfuric acid in the battery). They also need to be completely recharged as soon as they run flat or else sulfation can occur.

Sustainable.co.za’s range of battery chargers contain an LED indicator to display voltage and charge current, so that you can monitor the recharge rate and determine how long your battery needs to recharge. Our battery chargers also have wide volt range, and come in 12V and 24V models. Whether you need a heavy duty battery charger to recharge your car, or something smaller for your Canon or Nikon camera, we have chargers for you.
