Operation manual V 3.2 for AcmeG series

The capacity of the battery will increase when the temperature rises. For example,
the capacity will increase by 6% when the temperature increases by 10º
C. However
the high temperature will accelerate the corrosion of the grid and cause water loss in
the battery, thus shortening the battery life.
As such it is always important to control the ambient temperature at the customer
premises. Please ensure room ventilation and usage of air-condition is recommended
in high temperature working environment.
3.2 Floating Operation
Floating voltage is chosen with the assumption of battery operating under the
optimal working condition. If the floating voltage is too high, the battery floating
current will get larger and increase the grid eroding speed, thus reducing the service
life of the battery. When the floating voltage is too low, the battery will not be able to
maintain its fully-charged condition. This will create sulphate and reduces the battery
capacity, hence affecting the service life of the battery. The floating voltage of Narada
AcmeG series battery is 13.5V/block under 25º
C. The temperature compensation is at
-18mV/º
C/block.
Floating voltage under different temperature is calculated by the following
formula:
