Solar power is free, but it is not reliably available on demand. A cloudy day, a short winter day or an incorrectly positioned panel can quickly upset the energy balance...

Anyone who lives in their a cabin/lodge all year round needs a constant supply of electricity. The fridge, heating control system and water pump don’t just run occasionally – they run every day. Lead-acid, AGM and GEL batteries have been reliably powering these everyday needs for years...

Converting a boat battery to lithium is quickly done. However, the charging system is often overlooked – and that is exactly where problems can arise...

How much battery capacity a boat needs depends on the power consumption on board. Choosing the capacity based on guesswork can mean either spending too much on the initial purchase or running out of power after two days without direct power.A better approach is to list every electrical load on board, note its wattage and estimate how many hours it runs each day.

Motorhomes and caravans place different demands on the on-board battery. With motorhomes, every kilo counts up to the 3.5-tonne limit. With caravans, mains electricity is usually available at campsites....

Caravaning means freedom. But freedom requires energy, and the right battery determines how long that energy will last. If you guess instead of calculating, you may find yourself without shore power...

You can always rely on your Banner battery if it has been well maintained. But what if your neighbour is struggling to start their car? Of course, you jump in to help and want to show off by quickly and simply performing a jump start. This is how to do it properly.

You can try to push your car with at least a second, or even better a third person, and then start it. This is because pushing creates kinetic energy which, in some vehicles, is transferred from the axle to the engine and thus enables jump-starting.
