Needless-to-say, if a battery box is mounted inside, heat in the living area will help to improve its performance. However, many batteries are mounted externally where ambient temperatures can be much lower.

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 In contrast, a leisure battery has to provide a steady flow of current over a prolonged period and seldom gets replenished until the user recognises that its voltage level has substantially fallen. That’s when a re-charge is duly provided. If left long in a discharged state, a battery will generally not regain its former condition. Furthermore, manufacturers often recommend that re-charging is commenced when a battery drops to 50 per cent of its full condition. The eagle-eyed will notice that we had six pairs of wires to connect to our five-way junction box. We resolved this by putting the solar panel and hydraulic leveller wires together into the same connection. So I soldered the wire onto the connector, held my breath, and plugged it in. It worked first time!Apply a thin film of grease or petroleum jelly, such as Vaseline, to a battery’s terminals (see right). 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: An AGM battery has lead plates in each cell and the manufacturer uses a machine to add highly compressed glass fibre into each compartment. The fibre then absorbs the acid electrolyte. During manufacture, air is also drawn from the casing and a pressure relief valve is fitted. These processes render the finished product more costly than a conventional ‘wet lead-acid’ leisure battery but AGM products can generally achieve many more recharging cycles – thereby achieving a longer working life. Category C is for users that require a lower capacity battery to cover basic operation of their habitation equipment for short periods away from a hook-up

Lithium iron phosphate (LiFePO 4) batteries are another form of very deep cycle battery. They're self contained units with their own on-board charge manager. Having elminated lead they typically weigh half as much as an equivelant output lead-acid battery so the weight saving is a benefit. They can also be fully discharged and recharged and during the discharge cycle they can retain a stable voltage level and they can be rapidly recharged. 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. Temperature– The stated capacity of a battery is expressed in Amp hours (Ah) but the quoted figure is only applicable when the ambient temperature is 25C. In reality, there are many occasions in the UK when it’s much colder than 25C and for every one degree drop in temperature, there’s an approximate one per cent reduction in a battery’s Ah capacity. Let’s take an example. If a battery which is nominally rated at 60Ah is operating in temperatures of 15C, this ten degree reduction will bring about a 10 per cent reduction in its capacity. This now means that it effectively performs like a 54Ah battery. The temperature issue can have adverse effects for caravan and motorhome users who enjoy winter sports. Not only will a battery face greater demands when providing their lighting, fan-assisted heating, and evening TV entertainment during long, dark evenings; its effective capacity is significantly lower than it would be in warmer conditions.

Or maybe a combination incorrect polarity and excessive current. i.e. Maybe the radio was protected against incorrect polarity but only up to the recommended 2.2 amps. Cost is the issue, they can typically be more than five times the price of a good quality lead-acid battery. Maintenance-free batteries Semi traction and traction batteries (also referred to as deep cycling batteries, lead-acid batteries, wet batteries).

As its name suggests there's broadly the same basic chemistry going with a reaction between lead and an acid but with these the acid is in a crystal form. This means there's very little liquid content with no risk of spillage making them safe to transport. The unique chemistry enables them to be very deep cycled with little risk of sulphation. They can be be around twice the price of a good quality deep-cycle battery but as they were originally designed for UPS use they're robust against continuous charging from a solar supply and can tolerate heavy discharge loads from an inverter for example. So bear in mind that conventional lead-acid batteries are not able to perform both starting functions and accessory supply functions with equal effectiveness. However, products called AGM batteries, described later, are better at performing both operations. Leisure batteries’ two-fold tasks The greater amount of lead in a genuine leisure battery and its more elaborate separators is reflected in its higher price and increased weight. Non-wet leisure batteriesThat is the situation we faced with, and the short term solution was to fit a smaller battery. It's ironic really that you have to reduce the size of the battery to cope with all the extra items wanting power. These junction boxes are intended for use at mains meter positions where there may be a need to feed more than one consumer unit. Being designed for 240 volts, they are more than happy at 12 volts although the phenolic urea construction (think Bakelite) does make them rather brittle. Nevertheless, this material has excellent insulating properties and will take some heat.
