Caravan Battery Charger Buying Guide
It’s essential to consider the amp rating of the battery charger before making a buying decision. The peak amps is a measurement of the highest number of amps that a battery can produce within a single millisecond.
This means that chargers that have a higher peak amperage can pull in more substantial levels of electrical current at a time without damaging itself.
In summary, the higher the peak amperage this indicates that the charger is of greater quality. However, this doesn’t signal the speed of the charging.
Regardless of whether you’ve been using a battery charger for years or you’re about to purchase your very first unit, you’d still favour a charger that’s quick and easy to operate.
You must ensure that your desired unit comes complete with a user manual guide or at least has online videos that you can use to help. If you’re a beginner, then it can be challenging to set up without these resources.
The size of your chosen battery charger will be dependent on your expected use. For example, if you plan to transport it and have it with you at all times, then you’ll want to choose a compact and lighter version. However, if you plan just to keep it at home, then a larger version won’t be a problem.
In the past, the size of the charger was often a fair reflection of how much power it could produce. Times have changed, and technology has progressed massively, so even the smallest battery chargers can generate a large amount of amperage.
If your battery charger has the jump-starting ability, then this can be a great addition. This feature allows you to jump-start your battery when it’s fully run out of power meaning there isn’t enough power to cause the crankshaft to rotate, which then helps to start the engine.
Generally speaking, the larger your vehicle engine, the higher the number of cold cranking amps your battery charger needs to be. Colder conditions can make it more challenging to jump-start your batter so a larger burst of electricity will be required.
Automatic Shut Off
The best caravan battery chargers will have an automatic shut off feature so when the battery is fully charged it will automatically send a trigger than cuts the charge to stop overcharging. Overcharging can cause damage to the battery, and an inbuilt microprocessor controls the automatic shut off.
This microprocessor can initiate multi-stage charging which ensures that the battery charges efficiently every time. It’s essential to check whether your chosen battery charger has this feature as it will extend the overall life of your caravan or motorhome battery.
If you’re on the move in your caravan and your battery dies, then you need a quick charge. Different batteries require different charging periods which can range anywhere from 2 – 12 hours. You also need to check compatibility with your chosen leisure battery monitor.
High-quality chargers will charge your battery significantly quicker whereas portable chargers will usually be slower at charging because they’re smaller in size. So although smaller chargers are easier to transport, their charging output may be slower.
The best caravan battery chargers often have numerous charging settings depending on your current needs. For example, if you’re in an emergency where you need to quickly charge, then you can switch to its fast-charging setting.
Although it isn’t good to continually use the fast charging setting, it has its uses. Of course, ideally, you’d always use the slow charge but if you’re stuck on the side of the motorway then added charging functionality can save you a lot of hassle.
The first thing you should consider is whether your chosen battery charger is compatible with your type of leisure battery. Some battery chargers can only be used with a specific type of battery depending on the voltages.
Using the wrong charger can lead to a range of problems including faults, non-charging or slow charging.
The simplest way to find out if your battery is compatible is by reading the instruction manual or checking on the battery/charger itself.
Electronic goods are made with hundreds of components, and all it takes is for one of these components to develop a fault, and the whole unit may stop working.
You need to ensure that you check whether your battery charger is supplied with a warranty as this will provide you with both peace of mind and product support if the unit becomes faulty.
Warranty length varies from product to product but generally speaking, they will be no shorter than one year and can be valid up to a lifetime.
It can often be more cost-effective in the long run to buy a more expensive charger that has a more extended warranty vs a cheaper charger with no warranty.
Buying a caravan leisure battery charger used to be an expensive outlay; however, with the advancement in technology this has done two main things; increased the number of features & decreased the prices.
Even the best battery chargers will cost under £80-90 and have all the added features that you need to quickly and effectively charge your battery.
