For maintenance free battery, it's free maintenance in the
operation. But we can only use it in proper operation to keep the
long lifetime of the battery, (1) Battery Installation Batteries
should be installed possibly in a clean, cool, ventilated and dry
place. The battery should be placed upright. Each terminal between
the batteries is connected firmly. (2) The ambient temperature
Ambient temperature is important factor for the battery operation.
When the ambient temperature is too high, Battery plate corrosion
will be increased, while absorbing more moisture; When the ambient
temperature is too low, the battery will not be full charged. All
this will affect the battery life. Therefore we suggest the working
ambient temperature is around 25 º C. (3) The charge and discharge
current Battery charge and discharge current usually uses the
concept C, the actual value of C is related to the capacity of the
battery. For example, a 100AH battery: 1C = 100A. Charging current
is around 0.1C; The charging current must not be bigger than 0.3C.
Discharge current general requirements in 0.05 ~ 3C range. (4)
Charging voltage After the battery is full converted to float
charging, the float voltage is around 13.0V. If the charging
voltage is too high will cause the battery overcharge, otherwise
the battery will not be full charged. Charging voltage is abnormal,
it may be caused by the battery configuration error, or it may be
caused by controller failure. Do not choose the controller with bad
quality. (5) The depth of discharge Depth of discharge of the
battery life is also a important factor for lifetime of battery,
the deeper the battery discharge, the fewer the number of cycles,
so battery should avoided from deep discharge. (6) Regular
maintenance Battery should be regular checked in every period time
after used, such as check its outlook, measuring the average
voltage of each battery, etc. Excellent performance 1. High
efficiency Discharge: Sealed reaction efficiency rate more than
99.9% 2. Low rate of liquid loss: Liquid loss rate is half lower
than adsorbed type battery. Effectively alleviate the electrolyte
early dry. 3. Low Self discharge: Storage with power for two years
among temperature 25º C is possible. Storage time is 4times longer
than adsorbed type battery.
