Replacement battery for DAITEM 330-23 and 330-23x

This nickel-zinc battery replaces the original DAITEM 500798 and 951-21X packs used in alarm system panels. It delivers a nominal 3.7 volts and a capacity of 3350 milliamp hours for 12.40 watt-hours of energy storage. The pack measures 67.00 by 20.00 by 18.60 millimetres and weighs 52.0 grams. It is intended for indoor security installations that require a direct-fit replacement cell.

Verify model and part numbers before ordering

Confirm that your device is a DAITEM 330-23 or 330-23x and that the original battery carries part number 500798 or 951-21X. Check the physical dimensions against the 67.00 by 20.00 by 18.60 millimetre outline to ensure it fits the compartment. Ensure the connector polarity matches the original pack before making the connection. A new cell reaches full performance after two or three complete charge and discharge cycles. Avoid low-quality third-party chargers as they can shorten service life.

Steady discharge in alarm standby use

The nickel-zinc chemistry provides a stable 3.7 volt output during the long, low-current standby periods typical of security panels. Rated at 3350 milliamp hours, the cell supports extended backup duration between mains failures. Integrated protection guards against overcharge, over-discharge, over-voltage and short-circuit events during continuous float charging. The pack is certified to ISO 9001, RoHS and CE standards for safe, durable operation. Do not disassemble, expose to fire or water, or store above 60 degrees Celsius.
