"VT-EV" Series Sealed Type Battery Comparison
The "VT-EV" Series Sealed Type Battery comparison highlights the differences between Normal Type VRLA Batteries (VT Series) and Deep Discharge Long Life VRLA Batteries (EV Series). Designed for distinct applications, the VT Series is suited for moderate discharge needs, such as UPS and telecom systems, while the EV Series is optimized for deep cycle and high-discharge applications, such as electric vehicles and solar systems. Each series utilizes specific materials and structures to enhance performance, durability, and efficiency in their respective use cases.

Silver-Ca-Tin
(Alloy)

 Due to the fine crystal organization, improve corrosion life; Due to the conductivity of silver alloy up and internal improvements in diet and thus improve the charge and discharge performances.
Separator/Electrolyte AGM or GEL AGM, GEL and other additive to recover and improve performances caused by over discharge High conductivity, The electrolyte density is uniform on the surface of the plates.
Active Materials
Of Plates		 The active material is a spinning crystal organization, and designed to apply to standby power (Tetragonal)
(+)
(-)
Due to the component of α-PbO2 increased, and the pasted conductive material of NANO decreases the electrical resistance.
Container Normal use ABS For heat-resistance high impact use ABS Resin Good endurance
Design Of
Electrical Capacity		 Normal High rate Capacity ratio under the same volume: High
Charging Capacity Suitable for low rate and middle rate of discharge Design it for high-efficiency discharge High current
Charging Efficiency Discharge about 120% to charge (D100/C120=0.83) Discharge about 110% to charge (D100/C110=0.91) Short charging time
Inside Of Battery - 20~25% lower than normal Good performance on low temperature
Insantaneous Current Discharge Current Can be used till load suddenly changes within 1CA Can be used till load suddenly changes to max. 3CA * 1CA=the same current discharge with he nominal capacity (50Ah=50A)
Characteristic Of Re-Charge After Deep Discharge Charge at once when it’s discharged to be more than 80%. Charge 10hours ahead of no less than 50%. The battery which is charged for 15hours after stored for 30days can recorver 90% performance Recharge under repeated deep discharge will get supreior performance
