Car battery chargers

The car battery is the heart of your car, so it's important that you take care of it. And what happens if that heart stops beating, perhaps because you've left the lights on, the temperature drops or you only drive for short journeys? Maybe you don't drive your car every day, or maybe you have a boat, motorbike or other vehicle that's only used infrequently. Is your car stored for winter or other seasons? There's a risk that your car won't start again when you take it out of storage. These are all reasons why car batteries die, but in many cases, car battery chargers can fix the problems you and your car battery are having, get you back on the road and even extend the life of the battery by up to three times. Our special maintenance modes also mean that if you have a vehicle in storage, you can connect car battery chargers at any time without the risk of overcharging or undercharging your car batteries. You need a car battery charger to deal with such a situation.

Things to consider when buying car battery chargers

There are a few things to consider when choosing car battery chargers. You should first be aware of your car's battery capacity - this is given in ampere-hours or ampere-hours (Ah) - and engine size - in many cases there are different battery charger cars for different sizes of car batteries. For example, a smaller battery found in motorcycles and classic cars can be charged with a lower power car battery charger compared to a larger high performance car - your car battery charger 's output power needs to increase with engine size. Make sure the one you plan to buy is robust enough for your car's engine.

Battery type is the second factor. There are car battery chargers that are designed to work with lead-acid and/or lithium batteries. When it comes to lead-acid battery chargers, some of them may only work with certain types of batteries, such as wet-cell, gel and AGM batteries.

You can look in your car's manual or under the bonnet to find out the size, type and chemistry of the battery.

What features should I consider?

Although the primary purpose of car battery chargers is to charge your car battery, it's worth thinking about battery maintenance too and there are certain features and functions that can actually help extend the life of the battery by up to three times. So think about maintenance. If you don't have specific maintenance schedules for batteries on vehicles that are stored for long periods of time, you run the risk of overcharging or undercharging the battery. The reconditioning mode is good for restoring seemingly dead lead-acid batteries, and a special wake-up mode for lithium batteries is important if the battery has been switched off due to built-in battery management systems.

When choosing which model to buy, you should therefore take into account how you will use these car battery chargers. We've put together a summary of some of our best-selling car battery chargers to help you choose the right car battery charger.
