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. 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. 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: On the other hand, caravans only have leisure batteries, and these need to be charged to ensure your 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?

maintain your leisure battery will keep it going for as long as possible and can help reduce the cost of running 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. Leisure batteries should be tested for both voltage and state of health regularly. On many vehicles,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. 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?

Standard leisure batteries (also referred to as auxiliary batteries, deep-cycling batteries, lead-acid batteries, wet batteries).
Types of conventional lead-acid batteries:
From 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. Not surprisingly, batteries are made to be ‘job specific’. For instance, a conventional car battery seldom lasts long when asked to provide a 12V supply in a caravan or motorhome. This is partly because its lead plates are thinner and its separators (described later) are different, too. The 12V equipment in a caravan or motorhome relies on a leisure battery. This important item is not normally supplied with a new caravan whereas most new motorhomes have one as standard. Batteries that are designed to start a vehicle are made differently from batteries specifically intended to run caravanning appliances. This is because their operating requirements are different. For instance a vehicle battery has to provide a high current surge to start an engine, but once that has been achieved, a vehicle’s alternator immediately replenishes the power it provided. Moreover, in a genuine leisure battery, these envelopes also contain glass fibre sheets to press against the lead oxide paste held in each plate. This combats the tendency during constant re-charging for the paste to become loosened and then completely detachedfrom the lead grid. 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.
