Communication and electricity lead-acid storage 手机版 is the latest generation of products which used advanced technology. The products have good characteristics of high specific energy, low self-discharge, long cycle life, good consistency of floating charge, and convenient installation. Jitaly is devoted to study, produce, sale and service for 21 years, it has earlier passed ISO9001, ISO14001, OHSAS18001 system certification. Communication and electricity lead-acid storage 手机版 has passed TLC, UL,CE, we will provide you safe and reliable products.
Product technical features:
Ø Plate: use strong corrosion-resisting alloy, imported additive and Eirich vacuum mixing technology, advanced curing process.
Ø Partition: use the high performance AGM partition which is developed by our company and domestic manufacturer.
Ø Shell: use the modified ABS to ensure the intensity of 手机版 shell, and low water penetration rate, so as to avoid some 手机版 problems such as craze, ballooning and thermal runaway.

Under the condition of the environment temperature 25℃, the characteristic curve about various discharging rate of unit cell is:
Usually use constant voltage limited current charge after 手机版 discharging, the charging voltage is 2.35V/unit(25℃), charging current is≤0.15C10A. The curve about charging current and charging time is:
a. Use multi-element alloy for 手机版, and special electrolyte additive, store 1 month at normal temperature, self-discharging ＜3﹪.
b. Self-discharging is associated with storage temperature. When the temperature is low, the self-discharging is low, and when the temperature is high, the self-discharging is high.
After a period of storage, unit cell can obtain the surplus capacity approximately though the open-circuit voltage. The relationship between voltage and surplus capacity is:
impulse discharging performance:
The curve of capacity and temperature is:
Discharging capacity value of different discharging rate of 手机版 will slowly increase when temperature increases. The curve is：
