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 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. Products made differently such as gel, lead-crystal, lithium and AGM batteries are mentioned later in this guide. Conventional lead-acid starter and leisure batteries have inspection caps so that the level of acid can be inspected in each of the cells. This also enables the cells to be topped-up using de-ionised water (also sold for steam irons) so that the electrolyte just covers the top of the lead plates. Next, you fit a mover and a second, heavier, pair of leads appears. Space inside the battery box starts to get tight. You shorten the new leads to help, but now you have to disconnect the battery before you can lift it to the ground.

Whereas a 12V battery is unlikely to cause electrocution, if the terminals or their couple cables are shorted-out, it can cause a fire.The two existing glands on the left of the box proved perfect for the new cables from Maplins, each one making a good seal. The standard (i.e. ‘wet’) starter and leisure batteries described here usually have a polypropylene container (available in standardised sizes) and moulded with compartments. 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: 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 batteries Terry Owen explains how to how to wire a leisure battery safely and attach multiple electrical devices to your caravan's battery. The problemwith your leisure battery

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: 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. With the mains charger switched off and the battery removed it was time to unscrew the four cable glands and remove all the wires.

Leisure batteries’ two-fold tasks

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. When inspecting battery cells, wear safety clothing including eye protection and gloves. Battery acid also damages clothing. Some leisure vehicles, such as those used for off-road quad bikes and jet skis, have a greater likelihood of tipping over. An accidental inversion might also result in the loss of a battery’s corrosive acid which, in turn, might cause personal injury. In response to this, batteries are installed which have a non-spill electrolyte in the form of a gel. Unlike a ‘wet’ battery, a gel battery’s casing is completely sealed. Recently, some imported motorhomes have been fitted with a gel battery rather than a lead-acid battery, but this is for added safety during a crash. From an electrical perspective, batteries with a gel electrolyte are unlikely to perform any better than wet-acid types. Also be aware that when recharging a gel battery, the charge voltage must not exceed 14.2V. Information on charging requirements is a subject in its own right.

Semi traction and traction batteries (also referred to as deep cycling batteries, lead-acid batteries, wet batteries). Apply a thin film of grease or petroleum jelly, such as Vaseline, to a battery’s terminals (see right). 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.batteries as they aren’t designed for starting vehicles. To get the amp rating, simply multiply the 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. multimeter or voltmeter. Always ensure that all electrical appliances and consumers are switched off 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.

That 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. 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 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 Battery manufacturers often strongly advise that a battery receives a re-charge when its capacity falls below 50 per cent of its full condition. It is also added that you should never run a leisure battery until it is virtually ‘flat’. Further details are covered in the battery charging guide.

Standard leisure batteries (also referred to as auxiliary batteries, deep-cycling batteries, lead-acid batteries, wet batteries). We scoured the internet for a suitable junction box and found that Screwfix sells a five-way double pole unit rated at 100 amps and capable (in theory) of taking wires up to 25 sq mm. Tool Station has something very similar. The cost is around seven pounds.
