HRESYS DZM Series Valve Regulated Lead Acid Gel Battery is specially designed for motive power
applications including electric bikes/scooters, electric tricycles, electric motorcycles and other device
require DC power source. With international leading technologies and State-of-the-art automated
manufacturing,DZM series offer long cycle life, large current discharge capability , high consistency ,
reliability and safety, and environmental-friendly.
- Long Cycle Life : Exceptional cyclic performance above 600 cycles @80% DoD
- Reliable Seal Structure: Mount in any position except inverted
- Optimal Design : Besides the benefits of VRLA battery, it is maintainable that can prolong the service
life by up to 50% -100% or more
- Multi-purpose Application : The battery can be floating application as well as cyclic application
- Low Self-discharge : Adopted high quality grid alloy and high purity electrolyte, low self-discharge and
low water- loss
- High Reliability and Safety : Adopted enhanced ABS container and special design safety valve to ensure
battery high durable, safe and reliable.

2. Charge Characteristics
Recommend 3 Stage Charge Mode:
S1 : Charge with constant current 0.12C2A~0.15C2A to 2.46Vpc, then turn to step 2
S2 : Charge with constant voltage 2.46Vpc to current drop to 0.03C2A, then turn to step 3
S3 : Trickle charge with constant voltage 2.30Vpc , end charge as current approaches zero
