1) 体重比能量高，内阻小，输出功率高；
2) 充放电性能高，自放电控制在每个月2% 以下（20℃）；
3) ***性能好 , 在深放电或者充电器出现故障时，短路放置30天后，仍可使用均衡充电法使其***容量 17、蓄电池的浮充电压是指在环境温度为25℃ 下充电电压值，当温差超过10℃ 时，必须修正浮充电压，否则会损伤蓄电池。环境温度升高1℃ ，应降低浮充电压0.003V/单格；相反，则升高浮充电压0.003V/单格。；
4) 由于单体电池的内阻、容量、浮充电压一致性好，充电时，应在外接一直流电源（充电极或整流器），使正、负极板在放电后生成的物质***成原来的活性物质，并把外界的电能转变为化学能储存起来。 因此电池在浮充使用状态下无需均衡充电。
6、温度适应性强： 可在-30℃～50℃下安全、放心地使用；
7、使用和运输安全简便： 满荷电出厂，无游离电解液，电池可横向放置，并可以无***材料进行水、陆运输；
8、经济实惠： 柏克蓄电池极高的性能，超长的使用寿命，极低的维护成本确保用户得到的是经济实惠的产品。
1、当前电池放电技术分析
1.1离线式放电法技术分析
(1)将其中一组电池脱离系统后，一旦市电中断，系统备用电池供电时间明显缩短，何况此时尚不清楚另一组在线电池是否存在质量问题，此放电方式事故风险性高。如要用此方式放电，建议提前启用发动机组，并确保发电机组、开关电源等设备能正常运行，保证安全;
(2)离线放电结束后的电池组与在线电池组间存在较大电压差，若操作不当将引起开关电源和在线电池组对离线放电后的电池组进行大电流充电，产生巨大火花，易发生安全事故。用此方式放电，需要配备一台整组智能充电机，对该离线电池组先充电***后再并联回系统，以解决打火花问题，这样将使系统更长时间处于单组供电状态，事故风险高。另通过调整整流器输出与被放电的电池组电压相等后进行***连接。上述操作一定要谨慎操作;
(3)此放电方式操作时既要脱离电池组的正极，又要脱离电池组的负极，尤其是脱离电池组负极时需要特别小心，操作不当引起负极短路，将造成系统供电中断，导致通信事故的发生;
(4)此方式是将电池通过假负载以热量形式消耗，浪费电能，影响机房设备运行环境，需要维护人员时刻守护以免高温引发事故。
