If you have recently disconnected a charger or have been driving a motorhome or towing, a reading will be higher than normal. After a battery has been receiving a charge, it is recommended to let it settle for at least four hours before taking a voltage reading.

You buy a new caravan, and there are just two leads to the battery - a positive and a negative. You can probably even lift the battery out and place it on the ground without having to disconnect them. It's all very straightforward and easy to manage. State of health testing should be carried out using a suitable conductance type tester. This type ofFrom this information decide what size battery will likely be needed depending on how long you are away from a charging source. It is likely that this is not enough to meet your needs and will have to consider a top up charge. This will be covered in more depth in the Battery Charging guide. As mentioned earlier, AGM batteries are unusual in that they can act as starter batteries as well as leisure products. For instance, some recent cars are fitted with a supporting AGM second battery to run the many electronic aids now being installed. Similarly, their notable performance is recognised by caravanners wanting a task-specific support battery to specifically run a motor mover. This is why a caravan’s 12V accessories should not be run directly from a charger – i.e. without a battery installed in the supply system. Battery anatomy batteries as they aren’t designed for starting vehicles. To get the amp rating, simply multiply the

Semi traction and traction batteries (also referred to as deep cycling batteries, lead-acid batteries, wet batteries). On the other hand, caravans only have leisure batteries, and these need to be charged to ensure your What size leisure battery do I need? – You will first need to work out what your consumption is going to be on the 12V equipment you use and for how long it is used then, if required, factor in what seasons you go away. An example is shown below: Although a key function of a leisure battery is to run 12V appliances, it also performs a second important function. Bearing in mind that it is permanently linked to a caravan or motorhome’s built-in charger, a leisure battery is also able to smooth out any irregularities in the supply received from this device.

In consequence, it cannot cope with repeated heavy discharge and recharge cycles. Conversely, a standard ‘wet’ leisure battery doesn’t perform well as a starter battery either. This guide focuses on lead-acid batteries which are manufactured for particular tasks but in recent years we've seen an increase in the availability of lithium batteries so they're now worth a mention. They also get classified using various names. Types of conventional lead-acid batteries: Each compartment creates a nominal 2.12V, thereby creating a total of around 12.7V for a fully-charged battery. Each compartment houses a series of positive and negative lead plates. These have a grid construction so that lead oxide paste can be pressed into all the apertures.

The compartments in the casing of lead-acid batteries are also filled with diluted sulphuric acid referred to as the electrolyte. The casing also has a gas outlet for releasing any hydrogen created during re-charging. This must not be allowed to become detached. Never leave a battery in a discharged state. If recharging is delayed, a situation known as sulphation occurs in which a white deposit forms on a battery’s plates. In general this is an incurable condition, which renders a battery useless.Standard starter batteries (sometimes referred to as calcium batteries, cranking batteries, lead-acid batteries, wet batteries). This gives your typical daily consumption. It is surprising how much power is required and how we take it for granted. Heavy consumption equipment like motor movers will have a detrimental effect on the battery performance for the reasons explained below.
