Lead-acid rarely charges at even 1C (usually 0.2C), so unless you had a 200Ah motorcycle battery, you put it through a hell of a time. $endgroup$ – Bryan B Commented May 19, 2017 at 20:52
What happens if an AC voltage is applied to a battery?
It''s fairly common to see a lead-acid battery charged using rectified AC. As long as the charging current isn''t beyond the capability of the battery, it will ''work''. If there isn''t a series resistor somewhere, or some primary-side limiter, the winding resistance of the transformer could be what''s limiting the charging current.
