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. Although they are more expensive than the other two types of batteries described above, they are the more durable choice.
