Product Details


Product Feature Of Mini Solar Storage Battery Battery

Long design life (25℃):  5 years;   Low self-discharge rate: ≤3%/month

High sealed reaction efficiency: ≥99%;   Wide operation temperature range: -20℃~60℃


compact design, shorter internal connectors between cells, thus low internal resistance


Pasted flat type, with patent formula of AM


using improved AGM separator, higher assembling pressure to increase cycle life

Terminal sealing

double sealing techniques(mechanical+epoxy gule)

Product Information 

1. Long shelf life
Can be stored for a long time period and no need to recharge during storage .Battery left-over capacity can be as high as 70% after being stored for 1 year and can be restored to 85% of its full capacity when fully recharged.
2. Over discharge performance under low voltage
This battery can be restored to 80% of its full capacity while others only being rendered to failure because of the sulfuration of the sulphur-acid and its consequent maintenance, after subject to long period of repeated over –discharging due to frequently engine igniting, lighting and insufficient charge for the battery caused by short distance driving and low speed.
3. Over discharge performance under high voltage
Being charged at 16V(not recommended ,though),this battery can be as high as 95% of its full capacity, no drying up in the electrolyte due to little gas releasing and all released gas being absorbed by the plates, while this kind of sealed lead-acid battery usually being charged by a external 14.8V charger which being designed with different emphasis between amperage and voltage(because the charge voltage for flooding lead acid battery is usually at 16V,so the prevalent charge voltage is 16V),it will be soon rendered useless caused by drying out of the electrolyte if the ordinary battery being charged by a 16V external charger.
4. Quick charge acceptance
This battery can quickly absorb the momentary charging energy generated by vehicle _borne generator and braking, testing date shows that it can absorb 70% of the energy released while others only 40%,after being charged under this kind of condition for 1 hour.
5. High multiple rates starting performance
Small in internal resistance and self-discharge, normal temperature starting discharge multiple rates can be as high as 8C20 while other ordinary battery can only reach 6C20,so this battery can be used to substitute high power battery.
6. Super long life span
This battery’s life span is twice as long as ordinary battery’s due to its slow capacity attenuate rate under repeated deep discharge cycles.
7. Super long life span Battery’s consistency
The consistency and balanced discharge performance rendered special match for battery working group unnecessary and only need to replace the damaged one in case there is any, thus speeding the responsiveness of post sale service.

Compliant Standards 

1. GB/T19639-2005/ JIS C8702-2006/ IEC 61056-2002 
2. Passed ISO9001, ISO14001, OHSAS18001, UL, CE and TLC certificate.
