Battery specifications

Feature	Specification
Type	6 V, 9 AH, sealed, maintenance-free, valve-regulated,
	rechargeable, lead-acid battery.
Voltage	The battery modules have a battery string voltage of 36 V.
Charging	Advanced charging for faster recovery. Complete charge takes at
	least 48 hours. After approximately 24 hours, the batteries reach
	90% charge at default nominal utility voltage and no load.

IMPORTANT: The 48-hour timer for the overall charge cycle triggers at the transition from charge mode to float mode. For certain conditions such as heavily discharged batteries, battery condition, and so on, it may take longer than usual to reach float mode. In these cases, it may take longer than 48 hours to reach the rest mode.
