HZ Series

Small Valve Regulated Type

High-rate discharge small valve regulated lead-acid batteries featuring high energy density and space-saving design.

The HZ Series is a line of high-rate discharge small valve regulated lead-acid batteries that achieve high energy density and space-saving installation.

※This product is manufactured by CSB Energy Technology Co., Ltd., a group company of Energywith. (Country of origin: Vietnam)

Features

Suitable not only for standby use but also for cycle use.
Expected service life for standby use is 5 years at 25°C with 0.25CA discharge.
Expected service life for cycle use is 200 cycles at 100% depth of discharge (DOD) and 25°C.

※“Expected service life” refers to the period converted to constant 25°C operating conditions based on results from high-temperature accelerated life testing. This value is an estimate under specified conditions and does not guarantee battery life under all operating conditions.

Main Applications

UPS
CATV
Emergency lighting
Disaster prevention equipment
Disaster prevention and security systems

Note 1: The nominal voltage of lead-acid batteries is 2V per cell. These batteries consist of six cells connected in series inside the battery.
Note 2: F.V. is an abbreviation for Final Voltage, indicating the discharge end voltage.
Note 3: “C” in this table indicates the 20-hour rate capacity (C20). For example, for model HZ7.2-12, C (C20) = 7.2.
Note 4: Measured value (for reference) obtained using a Battery HiTester®.
Note 5: During operation (charging and discharging), it is recommended that the battery temperature be maintained between 5°C and 35°C. For storage, keep the battery at 30°C or lower whenever possible.
