Charge current decides how long a battery takes and, more importantly, whether the charger suits the battery at all. A large charger on a small battery overheats it; a 1A maintainer on a flat leisure battery will never catch up. Matching the two is the whole decision. Battery capacity in amp hours is the figure the charge current is read against.
Battery voltage narrows it further. Chargers here cover 6V, 12V and 24V, and a 12V charger on a 24V system does nothing useful. Dual and triple voltage chargers cover a workshop meeting cars, commercials and older vehicles on the same bench. A charger covering more than one voltage also removes the risk of connecting the wrong machine on a busy bench.
Smart or conventional changes what the charger does unattended. A smart charger reads the battery and steps through charging stages, then holds it without overcharging, so it can be left connected. A conventional charger applies current until it is switched off. Schumacher chargers run from 1A up to 20A with SIP CHARGESTAR machines alongside them.
Starter chargers add a boost function, delivering 120A to 360A briefly to turn an engine that will not start rather than only recharging. Bank stations charge several batteries at once, which suits a fleet or a workshop with stock.
