Battery Charger Buyer’s Guide – Maintenance charge your car battery cheaply and safely

Is your car often parked for long periods or do you only drive short distances? Car batteries recharge while driving, but if you don’t use your car very often or only drive shorter distances, your car battery won’t be able to charge properly. A solution for this is to invest in a car battery charger. In Biltema’s range you will find both car and motorcycle battery chargers.

Choose a charger that suits your needs

Will the battery charger be used for maintenance charging or for charging a discharged battery? Will it be used for jump starting? Or all three? Before choosing a battery charger, you should decide what you need it for and what functions would be most helpful to you, since there are many different battery chargers on the market today. Some are simpler, while others have many different helpful functions such as jump starting and overcharge protection.

Battery type is a crucial factor

What type of car battery do you have? Some battery chargers cannot be used to charge certain car batteries, so you should therefore find out what type of battery is in your car. The most common battery types are lead-acid batteries, AGM batteries, EFB batteries, gel batteries, and lithium batteries.

Battery charging rate

The amperage you need from the charger is determined by what you will use the charger for. A battery charger that provides under 5 amps slowly recharges the car battery, which works great for maintenance charging. If you maintenance charge your car battery, you won’t need to worry about whether the car will start.

If you want your battery to charge quickly instead, you will need a battery charger with higher amperage – more than 5 amps. Some battery chargers with higher amps can also jump start your car if needed.
