Lithium - Lithium batteries are durable and perform well at extreme temperatures. They're maintenance free too. They are a modern alternative to other types and sort more energy with less weight. They can also deliver accurate data for power monitoring. They are, however, more expensive. Battery class categories 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.

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. The battery power used during the starting up process is then replaced by the alternator, which supplies the bulk of electrical current to your car's electrical systems, keeping your battery fully charged.

No. Although they look a lot alike, a car battery and a leisure battery discharge power differently. A car battery will release its power in one short, sharp jolt before being recharged via an alternator. The best leisure batteries release their power in a slow, controlled stream. Can I use solar power instead to recharge a leisure battery?

As Lifesure notes, the best leisure batteries also can smooth out and correct irregularities in a power supply. How long should a battery last? Category A is for higher storage capacity for people who frequently use their caravans or motorhomes away from electrical hook-upsDynamic Silver car batteries are a great all-rounder, providing more power than our blue range at great value. Suitable for many manufacturers such as Ford, Vauxhall, Renault, Citroen, VW, Peugeot, BMW, Audi, Skoda, Volvo, Honda, Fiat and many more. They offer excellent cold start performance and reliability.
