No water supply, easy maintenance
The use of special design to overcome the phenomenon of electrolytic water loss in the battery charging process, the battery in the use of the electroliquid volume and specific gravity almost no change, so the battery during the service life of no water refill, simple maintenance.
Safe sealing and easy installation
There is no flowing electroliquid in the battery, the battery can be installed and used vertically or sideways, there is no electroliquid leakage, and the battery will not produce acid fog during the normal charging process. Therefore, the battery can be installed in the office or supporting equipment room, without the need to build a special battery room, reducing the project cost.
Using the lead calcium alloy grid with good corrosion resistance, the normal floating life can reach more than 10 years at 25°C ambient temperature.
High power discharge performance is good
The high quality plate and glass fiber separator with very small internal resistance are used, and the assembly is tight, so that the internal resistance of the battery is very small. In the temperature range of 40°C~60°C for large current discharge, its output power can be about 15% higher than that of conventional batteries.
Easy to install and use
The battery is fully charged when it leaves the factory and can be installed and put into use after receiving the battery.
WEIDA Battery products Advantages:
1. Good safety performance: no electrolyte leakage, no battery expansion and rupture under normal use.
2, good discharge performance: smooth discharge voltage, smooth discharge platform.
3, good shock resistance fully charged state of the battery is completely fixed, with 4mm amplitude.16.7Hz frequency vibration for 1 hour, no leakage, no battery expansion and rupture open circuit voltage normal.
4. The fully charged battery with good impact resistance will naturally fall from a height of 20cm to a hardboard of 1cm thickness 3 times. No leakage, no battery expansion and rupture open circuit voltage is normal.
5, good overdischarge resistance 25 degrees Celsius, fully charged state of the battery for a fixed resistance discharge for 3 weeks (resistance value equivalent to the battery 1CA discharge requirements of the resistance), the recovery capacity of more than 75%.
6, good overcharge resistance :25 degrees Celsius, fully charged state of the battery 0.1CA charging for 48 hours, no leakage, no battery expansion and rupture open circuit voltage is normal, capacity maintenance rate of more than 95%.
7, high current resistance good fully charged state of the battery 2CA discharge for 5 minutes or 10CA discharge for 5 seconds. The non-conductive part is fused. No appearance distortion.
