BATTERIES

Lead-Acid batteries are the most common type of battery in the storage world due to their technological maturity and low price. However, they need to be stored in a ventilated place and to be maintained monthly.

AGM batteries are lead-acid batteries with a solid, rather than liquid inside. This feature ensures that they are maintenance free and can store more energy than a conventional battery.

GEL batteries are similar to AGM batteries, the only difference being that silica has been added to the electrolyte so that it is as a viscous gel rather than a liquid. Compared to AGM batteries, they excel at slow discharge intensities and higher ambient temperatures.

Lithium batteries mark the beginning of a new era of energy. Indeed, they tolerate complete discharges, they have the best energy densities, they are bluetooth and can even be self-heating. They are also the most resistant to high rates of charging and discharging. Although they are more expensive than the other two types of batteries described above, they are the most durable choice.
