Best Leisure Battery Chargers for Caravans and Motorhomes Buying Guide
There are several factors that we would advise you to consider before investing in a leisure battery charger.
Doing so will help you to select the best product for your needs.
The Type of Portable Leisure Battery Charger
Portable leisure battery chargers are available in different variations, each of which uses a different type of technology.
The cheapest option is an unregulated voltage battery charger and as suggested chargers of this kind do not regulate the voltage and if left unattended they may overcharge the battery.
The next option is a semi-automated battery charger which will turn itself off once the charge has reached the set voltage. The final option is a fully automated battery charger.
Although chargers of this kind tend to be the most expensive, for many they are the preferred option. This is because unlike the previous chargers, they can be connected to the battery inside your caravan or motorhome without presenting risks of damage.
The functionality of a fully automated charger also tends to correlate with the temperature. In colder temperatures, a lower current and voltage is used and in warmer temperatures, a higher current and voltage is used.
You must choose the charger that is suitable for the leisure battery inside your caravan or motorhome to avoid any issues with faults or damage.
The Charging Time
The time taken for the battery to reach full charge can vary. For example, if you are charging a battery that is currently at a 75% charge, it is only likely to take a few hours to reach full capacity.
However, if you are recharging a battery that currently has no charge, it can take 24 hours or more.
The quality and performance capabilities of the charger are also going to affect how long this process takes. High quality offerings are likely to function at a faster pace than those that are poorly designed.
Battery Suitability
It is important to ensure that the battery charger is compatible with the leisure battery of your caravan and motorhome, otherwise, it is going to be ineffective in its purpose. Most battery chargers are compatible with a specific type of battery.
Using a charger that isn't intended for the battery in your vehicle can lead to possible damage and you may return to find that the battery is no further charged than it was first connected.
To ensure that your chosen battery charger is compatible, you should check the specifications of the charger as this will state the batteries suitability.
Vehicle Suitability
Not only is it important to ensure that the charger is compatible with the battery but it must be compatible with the size of the vehicle.
Again, the specifications will state the maximum size of the vehicles that it can be used with.
Checking these beforehand will confirm whether the charger can support the battery of your caravan or motorhome.
Safety Features
The safety features of the charger are crucial in ensuring that the battery doesn't become damaged.
Many will have LED indicators that inform you of any errors with reverse polarity and most will offer short and open circuit protection.
Ease Of Use
Ideally, your leisure battery charger should be easy to use.
Whether you have previous experience of using a charger or this is your first time using a device of this kind, one that is straightforward to use will prevent you from spending a while figuring out how the device should be used.
Most will come with an interface that displays each of the settings and functions. The battery charger should also come with instructions regarding how the device should be used.
Durability
Leisure battery chargers are going to be used outdoors so they must be constructed to withstand the elements.
They should also tolerate exposure to different temperatures without deteriorating in quality.
Most will have a rugged casing that protects the internal components from potential damage for enhanced toughness and reliability.
The device should also be dust and water-resistant.
Cable Length
The specifications will state the length of the cables and some may come with extending cables. The length of the cables will determine how much flexibility you have to work with the charger.
Though this isn't likely to prove hugely restricting in using the device, longer cables will provide you with more leeway in reaching and positioning the device and is particularly useful for batteries that are hard to reach.
The Size
Leisure battery chargers tend to be rather compact devices although you will find some that are slightly larger than others.
The setting in which you intend to use the charger will determine which size is best for your needs.
Though some may appear smaller than others they certainly do not compromise on the power that they provide.
If you are likely to require the use of the charger on the go you will benefit from investing in a smaller and more compact option. If the charger is going to be used in one place you may find a larger option sufficient.
The Amps
The amp rating of the charger is another factor to consider. Although the amp rating doesn't determine how fast the charger functions, it can be an indicator of the quality.
Those with a high peak amp rating produce more electrical current without causing damage in the process of doing so.
The Charging Speed
Many battery chargers feature multiple settings which function at different speeds. This allows you to select the most appropriate option for your circumstance.
Should you find yourself in an emergency you can opt for the faster setting which will charge the battery quickly.
Although it is possible to use the fast settings should your situation require you to do so, ideally, it is recommended that you opt for the slow speed setting.
The Cost
For many, the cost is going to be an influencing factor on their purchase. However, the market offers many options that aren't quite the expense that some may expect.
With an array of offerings from different brands, you will find some that are rather costly and others that are much more affordable.
It is important to ensure that the battery charger performs well. Many viable options retail below $70 so you don't have to break the bank when making your purchase.
The Brand
Some brands are renowned within this industry for producing high quality and reliable products.
Because of this, many customers may wish to make their purchase with these particular brands for greater confidence in the performance and functionality.
However, despite this, there are offerings from less-known brands that are just as worthy of your purchase.
We have included a variety in our guide above to highlight the range that the market has to offer.
The Warranty
Opting for a leisure battery charger that is covered by a warranty is preferable. The internal bodies of these devices incorporate many different electrical components, if any of these should become damaged, the device may stop working.
It may even be a case that the device was faulty upon receipt and so a warranty covers you in this instance.
The length of the warranty determines how long you are covered for and it can differ between brands with some offering longer warranties than others.
You will also find that some devices aren't covered by a warranty. If this is the case, it is important to consider whether this is something that you are looking for in your purchase or whether you are happy to proceed with your purchase without one.
Frequently Asked Questions
