Giáo trình công nghệ chi tiết sử dụng ắc QUY viễn thông dạng gel CG2 300v

CG2-300V

2V 300Ah(10hr)

Gel battery shows some distinctive advantages over flooded battery or AGM battery,
such as super thermal stability, high deep discharge capability, good recovery from
deep discharge , even if the battery is left discharged for three days, it will recover
to 100% of capacity. With the above-mentioned advantages, the gel battery has
long service life, specially suitable for motive power applications, such as golf trailer,
sruubber, folklift,etc.The deep discharge cycles increased 50% as compared with
the AGM battery.
