Product Information

Now you need to interpret the reading and although we talk about 12V batteries and accessories, this description is only nominal. If a leisure battery achieves a 12V reading, it is considered to have reached a discharged state.

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. 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. 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. 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:

multimeter or voltmeter. Always ensure that all electrical appliances and consumers are switched off 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 I soldered the wire onto the connector, held my breath, and plugged it in. It worked first time! When inspecting battery cells, wear safety clothing including eye protection and gloves. Battery acid also damages clothing.

Does the diode go between the fuse and the -ve battery terinal? So if that wire's connected to the +ve by mistake it's the first component in the firing line. Or it can go anywhere in the circuit? 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. Awesome! I'll build & test my reverse-polarity-protection with a bulb or volt meter before connecting the radio. As they cost pennies, I'll get some of each type, try a 1N4001 first, and if that blows then try a 1N5401.

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 As @winston1 , put a diode in the line, one of the 1N400x series will work (they cost about a penny each). And will reduce the voltage a bit, winner winner. regular monitoring and charging, especially when not in use for long periods. Yuasa, a top leisure battery brand, 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. On the other hand, caravans only have leisure batteries, and these need to be charged to ensure your

safely connect a 12v radio to a 12v leisure battery? How to safely connect a 12v radio to a 12v leisure battery?

If the battery outputs less than 12v, it's unlikely to damage the device, but it might not work, right? OK, but is there a component that can input a voltage of 12v +-3 and output exactly 12v? 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 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.The two existing glands on the left of the box proved perfect for the new cables from Maplins, each one making a good seal. If the charge level drops too low for an extended period (12.4 volts and below), permanent internal Apply a thin film of grease or petroleum jelly, such as Vaseline, to a battery’s terminals (see right). 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. I though the radio would just draw the power it needed, but maybe the battery amps exceeded the capacity?

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 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. 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. 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.Battery specialists sometimes diagnose a lead-acid battery’s condition using a hydrometer to obtain the specific gravity of the acid. Although this method has some advantages, it cannot be used on a sealed battery and the procedure is not discussed further here. However, by using an intelligent smart charger specific to the battery type and technology, you can
