A bit of free battery care advertising, it came via email, but it has some good points.
It is generally this time of year that a high number of caravan batteries fail. It can be tempting to blame the product but it could be due to how the battery has been maintained.
A leisure battery is not a fit and forget component of your vehicle, it has to be treated with care and kept in a good state of charge. If the battery is left unused it slowly discharges and some batteries can lose power quickly.
Due to the fact that few caravanners head off for a break in the winter the caravan can be parked up for a number of months. Unfortunately caravan inactivity affects the condition of its tyres, brakes, coupling, water system and leisure battery.
If you have a good-quality leisure battery, then continual attention helps keep it in good shape. There should be no reason that a leisure battery does not last until the next holiday season.
Although the battery will state 12V this is a nominal description. If a battery reads 12V it is considered to have reached a discharged state.
As a rough guide, if the voltmeter state reading is 12.7V or over it's 100% charged, if it reads 12.5V it's 75%, if 12.4V then 50%, if 12.2V it's 25% and if the reading is 12V or under, it is discharged.
Streetwize 12v Trickle Charger
Suitable for charging Lead Acid, Gel or Standard maintenance free Car batteries. Over-charging protection, Short Circuit protection, Overheating protection & Reverse Polarity Protection. LED power/charging indicators.
Maypole Battery Charger MP7423
4A Electronic smart charger for cars, caravans and vans. Suitable for 6V and 12V lead-acid 12V AGM batteries. Features: automatic charging current selection; 4 charging modes; 5-step charging including recovery and maintenance cycles; and memory function automatically re-starts charging if interrupted. Suitable for keeping your caravan Leisure Battery topped up.
There are different types of battery chargers. For example the built-in model in most caravans do not yield more than a 13.8V maximum charge, whereas to revive a heavily discharged battery you need a higher output.

The Volta Leisure battery charger is designed and made within the UK. The unit bears BSI approvals having passed rigorous safety testing. Utilising an intelligent 3 stage design, along with internal thermal and overload protection for added safety, the unit will operate down to -25°C to ensure operation in the coldest of winter months.
A solar panel can be an excellent source of power when off grid but it is not wise to connect the raw output of all but the smallest panels direct to a battery as overcharging could result. A solar panel designed for use with 12V batteries will be capable of producing voltages up to about 23V. When initially connected, this voltage will be dragged down by the load imposed by the battery but, as the battery charges, a point will be reached where the voltage becomes too high, resulting in damage to the battery. To prevent this, the output of the panel should be fed through a regulator, sometimes known as a charge controller. We have a wide range of Solar Panels and charge controllers online or in our store.
