ELK Products ELK-0650 Auxiliary Backup Battery
The ELK-0650 is a 6-volt, 5Ah auxiliary battery built to keep ELK Products security and access control panels running through a mains power interruption. It's a compact, sealed backup cell — at approximately 1.82 lbs (0.83 kg), it's easy to fit inside standard panel enclosures without crowding wiring or board space.
Key Features
- 6 Volt Nominal Rating: matches the auxiliary battery input on compatible ELK panels — confirm your panel's backup battery spec calls for 6V before ordering, since mismatched voltage will not charge or backup correctly.
- 5 Ah Rated Capacity (20-hour rate): the 20-hour rate figure is the standard way to size standby runtime — it tells you how much sustained current the battery delivers over a slow, steady discharge, which is the relevant number for backup power planning rather than a burst-load spec.
- 1.82 lbs (0.83 kg) Weight: light enough for wall-mounted or in-cabinet panel installs where you don't want the battery adding meaningful load to the enclosure's mounting hardware.
- Capacity Rated by Storage Period (Months): ELK specifies this battery's holding capacity on a monthly basis rather than a flat shelf-life number — plan replacement intervals accordingly instead of assuming indefinite standby readiness.
Integration & Compatibility
The ELK-0650 is sized as an auxiliary backup battery for ELK Products control panels and compatible security and access control hardware. Before ordering, verify your specific panel model's documented auxiliary battery requirement (voltage and Ah rating) against this unit's 6V / 5Ah spec to confirm fit.
Frequently Asked Questions
Q: What voltage and capacity does the ELK-0650 provide?
A: The ELK-0650 is rated 6 volts nominal with a 5 Ah capacity at the 20-hour discharge rate.
Q: How much does the ELK-0650 weigh?
A: Approximately 1.82 lbs (0.83 kg).
Q: Is the ELK-0650 (sometimes searched as ELK 0650) compatible with any ELK panel?
A: Confirm your specific ELK panel's documented auxiliary battery voltage and Ah requirement matches 6V / 5Ah before ordering.
Q: How is the ELK-0650's backup capacity rated?
A: ELK specifies storage/holding capacity on a monthly period basis rather than a fixed shelf-life figure.
The ELK-0650 is a straightforward spec to size correctly: 6V nominal, 5Ah at the 20-hour rate. When a panel calls for an auxiliary battery, that 20-hour figure is the number to check first — it's the sustained-discharge rating installers should use for standby runtime math, not a peak or surge rating.
Technical Highlights:
- 6 Volt Nominal: has to match the panel's auxiliary input exactly — a 12V-rated panel input won't work correctly with a 6V cell.
- 5 Ah Rated Capacity (20-hour rate): gives a consistent baseline for comparing standby runtime against other 6V auxiliary batteries in the same class.
- 1.82 lbs (0.83 kg): light enough that it won't stress typical panel enclosure mounting points.
Deployment Considerations:
- Confirm the target panel's documented auxiliary battery spec (voltage and Ah) before ordering — the ELK-0650 is sized specifically at 6V/5Ah and won't substitute for a panel calling for a different voltage.
- ELK rates holding capacity by storage period in months, so build battery replacement into scheduled panel maintenance rather than treating it as a set-and-forget component.
Good fit for a technician stocking a standard 6V/5Ah auxiliary replacement for ELK panel installs where the original battery has aged out of its rated storage period.
