6-DZF-12 12V 12Ah(2hr) VRLA GEL BATTERY
Chilwee DZF Series VRLA Gel Battery is specially designed for motive
power applications, i.e. electric bikes/scooters, electric tricycles, electric
motocycles and other device require DC power source. The DZF Series
adopts international leading technologies to ensure the batteries with
features of long cycle life, large current discharge capability, high
reliability and safety, and environmental-friendly.
FEATURES & BENEFITS
Non-Cadmium Design, Environment-friendly: Chilwee Battery has adopted internationally leading technology - Non-Cadmium
container formation Production Process technology, which is in the leading position in the industry. It helps to save energy 28.5%,
save water 90%, and non-discharge of waste water.
Super Long Mileage: Special active additives have been added in the positive plate to improve the consistency of the formated
active material after formation. This has been obviously improved the battery's charge/discharge efficiency, and more power can be
released during discharging. The mileage of each discharge is improved significantly.
Strong Motive Power: Super thin plate design is adopted to increase the area of electrochemical reaction, which enables the
battery has excellent large current discharge ability. Adopting cast-welding process to reduce the battery's internal resistance, so
the battery's charge/discharge efficiency is improved to enable battery with large power discharge capability.
Long Service Life: The Chilwee battery has excellent cycle life which can reach 600 cycles @ 80% DOD. The batteries are well
grouped to improve the battery bank's consistency in order to improve the battery bank's service life.
Non-Spillable and High Safety: The battery container and lid are made of Enhanced ABS material and they are sealed by epoxy
resin, so the battery is well sealed without any acid leakage issue. High accuracy safety valve has been applied to prevent battery
bulging, and safety valve and acid filter are used for preventing sparks splashed into battery to ensure the safety use of battery.
High Reliability: Improved negative material prescription and increased micropoles structure at negative helps to improve a lot on
charge/discharge performance at extreme temperature condition. Low water loss rate, high temperature resistance, and battery
deformation resistance.
