Caravan Leisure Battery Charger : How to choose it?

Manual or automatic charger?

There are both manual chargers and those that are automated on the market. The former offers the advantage of a more affordable price with the possibility of choosing between fast and slow recharging, but their use requires good supervision at the risk of damaging the battery.

The latest leisure battery charger models are fully automated which gives them a certain autonomy. Although more expensive, these chargers allow safe, unattended charging, in addition to several battery maintenance modes. Your choice will depend on your budget but also on whether you need additional options.

Supported voltage

Before making your choice on a particular model, it is essential to know the voltage supported by your battery. This information will guide your choice because it will necessarily be necessary to have a charger of the same capacity. Many of the chargers offered are suitable for 12-volt batteries, but there are some that are more versatile and suitable for both 6 and 12-volt batteries.

Load control device

If you want to acquire an automatic charger, it is necessary to check the type of charge control device incorporated. This device guarantees the autonomy of the charger and must at least include an automatic shutdown function and an LED charge indicator for greater safety. Some more sophisticated models can even be operated remotely.


A battery charger is above all equipment intended to be taken everywhere, hence the advantage that it is compact and light to be easy to transport. It should not clutter the boot of your car and should be as easy to use as possible.

Additional functions

Some chargers are equipped with different modes for optimising battery life, allowing them to be serviced regularly. Thus, there are very advanced models with protection against overheating, sparks, and reverse polarity, but also with battery test, float charge maintenance, or starting aid functions. The improvement of the tool can obviously impact the price, so it will be necessary to make your choice according to your real needs.

Why Buy a Good Leisure Battery Charger?

As a precaution

Short trips in the city and prolonged mobility tend to tire the car batteries, hence accidental discharges. To prevent breakdowns, it is best to have a battery charger in your boot that allows you to troubleshoot at any time without calling a mechanic.

To save money

A battery charger is a device that you can take with you everywhere to help out whenever a battery failure surprises us. It therefore considerably reduces repair costs for the mechanic. In addition, some chargers allow regular maintenance of the battery to extend its life.

For regular maintenance

Battery chargers have become very sophisticated lately. Many are not limited to just the charging function, but also help maintain the battery so that it can hold a charge better.

Secure loading

The chargers newly appeared on the market are also automated, some are equipped with a safety device against overcharging, overheating, and other phenomena capable of damaging the battery. They allow autonomous and safe use, with, depending on the model, a built-in automatic shutdown function.


The design of the leisure battery charger has continually improved and are no longer heavy and bulky, but compact and easy to carry. In addition, the automatic versions are self-contained and very easy to handle.

Tips to prolong the life of you leisure battery

  • Clean the battery terminals before recharging it.
  • Corrosion of your battery terminals causes poor electrical contact.
  • Remember to always connect the red positive (+) cable first. Then the black negative (-) cable. Then connect the charger to the mains. If you connect the negative first, you risk causing a short circuit that will damage the battery and possibly other parts of the vehicle's electrical system. Good car chargers provide protection against this.
  • Slower is usually better. Fast charging can save you time, but batteries always charge better with slow charging, hence the popularity of slow chargers. Smart battery chargers work much the same way when used normally, although smart circuits can reduce charging times significantly.
  • Check for a defective alternator.
  • Your car's alternator should maintain the charge on the battery. If your battery continues to be dead even after a full charge, it is possible that one of your alternators is defective.
  • Coat the battery terminals with grease designed for high temperatures. If you don't have a grease designed for high temperatures, it's best to check your battery clamps and terminals occasionally to make sure there is no rust build up. But, if you have some kind of fat, put it on the terminals of your battery. This will prevent rust and corrosion on the metal surface of the terminals.
