Features: 1, long life 0 2 with a good corrosion resistance of lead-calcium alloy grid at ambient temperature 25 ℃, the normal float life of up to 10 years??. ? 0? 22, sealing security, simple installation? 0? No flow of electro-hydraulic 2 batteries, battery vertical, lateral installation can be, without the risk of fluid leakage of electricity, but also in the normal process of charging the battery will not produce mist. Therefore, the battery can be installed in an office or equipment room, without separate special battery housing construction, reduce project cost. ? 0? 23, free water, easy maintenance? 0? 2 is specially designed to overcome the battery during the charging process of electrolysis of water loss phenomenon, the battery in the course of almost no change in the volume and the proportion of electro-hydraulic, so the battery during the life of completely without water and simple maintenance. ? 0? 24, a good high power discharge performance? 0? 2 with a high internal resistance is small plates and glass partitions, and the assembly is tight, so that the battery internal resistance is minimal. In the temperature range of -40 ℃ ~ 60 ℃ large current discharge, the output power can be higher than conventional batteries about 15%. ? 0? 25, easy to install? 0? 2 battery is fully charged at the factory, you can get the battery installed and put into use.
