This charger is suitable for 24V lead acid batteries!
An LED light indicates the charging status. Red = load / green = loaded
A rule of thumb for calculating the charging time results from the battery capacity and the charging current.
For example, with a completely empty battery with 12Ah capacity and a charger with 2A charging current, this roughly results:
12Ah / 2A = 6h charging time with 2A charger
Thus the battery is after max. 6h fully charged and the charger can be removed.
he charging time is of course shortened accordingly depending on the initial charge status of the battery.
