What Should I Look For When Buying A Car Battery Charger?
To choose the right car battery charger, there are a few things to consider. We have prepared for you the different characteristics that you can find on the car battery charger’s market.
The type of battery to charge There is a wide variety of vehicle and battery types. Not all chargers are compatible with every power and type of vehicle.
Please take into account the battery type that is installed in your vehicle:
- Lead-acid – Batteries found on most vehicles
- Slow discharge – Leisure, auxiliary or service battery, this type of battery can completely discharge and recharge for many cycles. Slow discharge batteries are suitable for motorhomes and converted vehicles.
- AGM (Absorbent Glass Mat) – More efficient than lead-acid batteries, AGM batteries are often found on vehicles equipped with the Start & Stop starting system.
- GEL – Composed of gel electrolyte EFB – Flooded batteries, common on small vehicles equipped with START/STOP function.
- Lithium – State-of-the-art batteries
The vehicles are equipped with batteries of different powers, which are independent of their composition:
- 6 Volt battery – Common on motorcycles
- 12-volt battery – Cars, motor homes, and motorized quadricycles are mainly equipped with 12-volt batteries, which makes them the highest standard.
- 24 Volt battery – The standard for heavy goods vehicles
- 48 Volt battery – Rarer, they are found on hybrid vehicles
Auto, motorcycle, or other, each vehicle has its own battery charger. You can also find versatile chargers that can operate on multiple battery voltages, to avoid buying multiple devices.
The power of the car battery charger The power of the car battery chargers are indicated in Ampere Hours (AH). The more powerful your charger, the faster your battery will be charged. Prefer high-power chargers, as they will be safer to use by avoiding any risk of overheating.
