Your present position:Products>>S Series

S series is specially designed for solar system & wind power system. According the condition of applications, Longway battery spent more than three year to develop and research S series. S Series performs excellent when it is recharged in high ambient temperature, discharge in low ambient temperature. S Series has good capacity retention under the poor recharging condition.



Product Standards
You can expect our batteries meet with the standards JIS, DIN, IEC60896-21/22. We have obtained ISO9001 &  ISO14001 certification. We have obtained UL approval (MH46789) for all types of batteries. We have obtained CE approval for all types of batteries.

General Features
1、Good cyclic property. Enhanced overcharge endurance and over discharge recovery property。
2、High purity raw material: ensure low self discharge rate
3、Using oxygen recombination technology: maintenance-free
4、Lower acid density, excess of electrolyte and larger distance between plates to keep battery at low  temperature and slow down plate grid corrosion speed
5、ABS material: increase the strength of battery container. (Flame-retardant ABS is optional)
6、Unique plate group configuration, high quality AGM separator and battery management system    ensure battery with a longer service life。
7、Special vent valve design: control water losing, prevent air  going inside
