MAINTENANCE-FREE PRINCIPL
For ordinary pocket type alkaline rechargeable battery,it is necessary to inject water into it and replenish the battery During floating charge operation.We take proper technical measures to solve the above problem.
We adopt high performance positive and negative active mass to improve its charge efficiency and decrease floating charge voltage and decrease the water-loss.
We adopt new type negative electrode and separator to decrease water-loss.When the battery is charged with floating current,some oxygen from positive can be Combined into water on the negative.So water loss In electrolyte is decreased.
We adopt high specific energy positive and negative mass to increase the volume specific energy and the store volume of electrolyte of the battery.

FEATURES
For this type of battery,it is unnecessary to inject and do balance charge within three years of maintenance-free .undEr Regularcondition.Its Service life is More Than 10 years for deep charge-discharge cycle at wide operation temperature range(-40°C~+60°C),It possesses the features of high reliability,resistant to vibration,shock,overcharge and over-discharge,low duty cost.
It can be used as stand-by power of electric power system and D.C. Operation power sources for railway (Coach,locomotive,metro),electric power,communication,steel industry and petrol-chemistry.
