The article presents an analysis of the types of high-capacity batteries, their applications and charging processes. The characteristics of stationary batteries are also listed. Comparative characteristics of parameters of modern various chemical accumulators of electric energy of lead-acid, nickel-cadmium, nickel-manganese and lithium-ion batteries are given. The processes occurring in the battery after several cycles of operation are considered as a change in its wear rate. Supplied from a 32 single source, batteries are considered both passive and active charging methods through sequential processes. The disadvantages and advantages of passive and active methods are listed. The influence of the parameters of the state of batteries in a state of voltage imbalance on the number of its cycles, charge level and discharge depth indicators depending on the charging time, on the state of voltage imbalance has been studied.
