Specification :

不需維護(hù)：電池在整個使用壽命期間不需要加水補(bǔ)液。 可靠性高、使用壽命長，特殊的密封結(jié)構(gòu)和阻燃外殼，在使用過程中不會產(chǎn)生泄漏電解液的缺陷。 重量、體積比能量高，內(nèi)阻小，輸出功率高。 自放電小，20℃下每月的自放電率不大于2﹪。 滿荷電出廠，無流動的電解液，運(yùn)輸安全。 無需均衡充電，由于單體電池的內(nèi)阻、容量，浮充電壓一致性優(yōu)良，確保了電池在使用期間，無需均衡充電。 堅固的銅端子，便于安裝連接，導(dǎo)電能力強(qiáng)。 計算機(jī)輔助設(shè)計和計算機(jī)控制主要生產(chǎn)過程，確保產(chǎn)品性能的一致性并達(dá)到設(shè)計標(biāo)準(zhǔn)。 *產(chǎn)品型號: YT640
