Special battery charging time
240KW/400KW industrial rooftop - commercial rooftop - home rooftop, solar power generation system.
The Max run depletes the battery more than normal and breaks up the crystallization, and then the 72 hr. charge gives the trickle charge a lot of time to rebalance the individual cells. When you receive a battery from iRobot, they don''t know how long the battery has been sitting around.
