Excel 12V 7AH SLA Battery

• Always store lead-acid in a charged condition. Never allow the open cell voltage to drop much below 2.10V. Apply a topping charge every six months or when recommended.
• Avoid repeated deep discharges. Charge more often. Use a larger battery to reduce the depth of discharge.
• Prevent sulfation and grid corrosion by choosing the correct charge and float voltages. If possible, allow a fully saturated charge of 14h.
• To reverse sulfation, raise the charge voltage above 2.40V/cell for a few hours.
• Avoid operating lead-acid at elevated ambient temperatures.
• Note: Wheelchair batteries don't last as long as golf cart batteries because of sulfation. The theory goes that a golf cart battery gets a full 14 hours charge whereas a wheelchair only gets 7 hours while the user sleeps.
