Transformer. The design of such devices is based on a transformer with a rectifier, operating on the principle of electromagnetic induction. It converts alternating power from the network into a small direct power for charging the battery. Transformer chargers are distinguished by increased reliability, simple design and low cost. At the same time, they have large dimensions and solid weight.

Pulse (inverter). Pulse (inverter) chargers affect the battery by supplying high-frequency pulses of low-amperage power. Using pulse chargers, it is possible to supply both direct and alternating power; sometimes they are used for mixed or combined charging of batteries. The vast majority of such chargers operate in an autonomous mode with automatic parameter control. Also, pulse chargers are 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.
