Product Details

DC12-90-Y of Deep-cycle AGM Battery

Mainly applied for eletrinic systerms, securing systems, medical equipment, shipping systems,telecommunications equipment,various testing machines,radio transceiver,the banking uninterruptible power supply system.railway locomotives, railway communications,emergency lighting systems, samll lamps, large UPS and computer backup power, fire extinguishing systems, electronic equipment, solar power system(off grid solar power system, solar street light system, sloar garden light system) and wind power system, no-traction battery.

Product Features of Deep-cycle AGM Battery                                                                 
1. Good Discharging Ability
Tight assembly technology ensures an excellent high-rate discharge performance.
2. Long Service Life
A unique corrosion-resistant grid alloy ensures Double Tech batteries have long service life.
3. Low Self Discharge
Using high purity raw materials ensures Double Tech batteries have less self-discharge.
4. Environmental & Non-polluting
Gas Recombination technology ensures the battery high seal reacting rate, which can prevent the acid fog from separating out.
5. Safe & Reliable
Efficient venting system automatically release excess gas when the pressure rises above the normal level & reseals the valves when it returns to the normal rate, which can protect the battery from bursting.
