Transformer. The design of such devices is based on a transformer with a rectifier, operating on the principle of electromagnetic induction. It converts alternating current from the mains into a small amount of direct current to charge the battery. Transformer chargers are characterized by increased reliability, simple design and low cost. At the same time, they are large and heavy.

Pulse (inverter). Pulse (inverter) chargers act on the battery by supplying high-frequency current pulses of small magnitude. With the help of impulse chargers, both direct and alternating current can be supplied; sometimes they are used for mixed or combined battery charging. The vast majority of these chargers work offline with automatic control of parameters. Also, pulse memory is many times more compact and lighter than transformer counterparts, but they are more expensive.
Battery capacity 12V
The capacity of batteries with an operating voltage of 12 V, for which a starter charger can be used. As a rule, modern units are not designed for one specific value, but for a range of capacities, which greatly facilitates the search filter according to the required parameters.
Note that although the discrepancy between the rechargeable battery in terms of capacity is not as critical as in terms of current or voltage, this does not mean that this parameter should not be paid attention to. Both too capacious and too “small” a battery will cause the charger to work in an off-design mode, which is harmful to both the “charger” and the battery, and can even lead to accidents.
