ELK Products ELK-0675 6V 7.5Ah Sealed Lead-Acid Backup Battery
The ELK-0675 is a 6-volt, 7.5Ah sealed lead-acid backup battery built to keep security and life-safety panels running when utility power drops. At 2.42 lbs (1.1 kg), it's a standard-format standby cell sized for control panel enclosures, access control power supplies, and other low-voltage equipment specified for a 6V DC backup source. If your panel calls for 6V rather than the more common 12V backup, the ELK-0675 (often searched as ELK 0675) is the correctly rated replacement or spare — don't substitute a 12V cell into a 6V-rated circuit.
Overview
Security panels, fire-adjacent life-safety equipment, and access control power supplies rely on a sealed lead-acid battery to bridge the gap between a power outage and generator or utility restoration. The ELK-0675 delivers 7.5Ah of rated capacity at the 20-hour discharge rate, at a nominal 6 volts DC — matching it to equipment that specifically requires 6V standby power rather than the 12V batteries more commonly stocked for alarm panels. Getting the voltage right matters: an under- or over-voltage backup cell can undercharge, overcharge, or simply fail to hold the panel up during an outage.
Key Features
- 6 Volts DC nominal: matches panels and power supplies engineered for 6V backup rather than 12V — installing the wrong voltage battery is a common and avoidable field error, so confirm your panel's rated backup voltage against the ELK-0675 before ordering.
- 7.5Ah rated capacity (20-hour rate): gives the connected panel a defined runtime budget during a power interruption. The 20-hour rate is the industry-standard way capacity is measured, so it lines up directly with the standby-time calculations most panel manufacturers publish for their backup power requirements.
- 2.42 lbs (1.1 kg) compact form factor: fits inside standard alarm and access control enclosures without modification, so a straight swap-in replacement is realistic in most panel cabinets already sized for a small sealed lead-acid cell.
- Storage capacity rated in months: sealed lead-acid batteries lose charge on the shelf even when not installed. A stated storage-capacity period means you can plan replacement or top-off charging intervals for spares kept in a truck or warehouse instead of discovering a dead battery at install time.
Integration & Compatibility
The ELK-0675 is a direct-fit backup power source for any panel, keypad power supply, or access control power module specified for a 6V DC, 7.5Ah sealed lead-acid battery. Before ordering, confirm the host equipment's backup battery specification sheet calls for 6V rather than 12V — swapping in the wrong nominal voltage will not properly back up the system and can shorten battery life. Pair the ELK-0675 with the rest of your access control power infrastructure, and check the panel manufacturer's documentation against a power supply planning guide if you're sizing backup runtime across multiple devices on one circuit. For broader panel and controller options from the same manufacturer, browse the ELK Products catalog, and if you're building out a full access control or alarm power backbone, review compatible power supplies and enclosures alongside this battery.
Frequently Asked Questions
Q: What voltage and capacity is the ELK-0675 rated for?
A: The ELK-0675 is a 6 Volt DC sealed lead-acid battery rated at 7.5Ah at the 20-hour discharge rate.
Q: How much does the ELK-0675 weigh?
A: Approximately 2.42 lbs (1.1 kg).
Q: Can I use the ELK-0675 in a panel that specifies a 12V backup battery?
A: No. The ELK-0675 is a 6V battery and should only be used in equipment specified for a 6V DC backup source.
Q: Is the ELK-0675 rated for standby storage before installation?
A: Yes, it carries a stated storage capacity rating expressed in months, which should guide replacement or recharge planning for spares.
I get calls from techs who grabbed a 12V battery off the shelf for a job that specified 6V — the ELK-0675 exists specifically to prevent that mistake. It's a 6 Volt DC, 7.5Ah sealed lead-acid battery rated at the 20-hour discharge rate, sized for panels and power supplies that call out 6V backup specifically.
Technical Highlights:
- 6V DC nominal voltage: matches equipment engineered for 6V standby rather than the more common 12V — voltage mismatch is one of the most common backup battery ordering errors in the field.
- 7.5Ah capacity at 20-hour rate: gives you a standard, comparable runtime figure to check against the host panel's published backup-time requirement.
- 2.42 lbs (1.1 kg): compact enough to drop into the same cavity as the original battery in most small alarm and access control enclosures.
Deployment Considerations:
- Always cross-check the host panel or power supply's battery specification sheet for 6V before ordering — the ELK-0675 will not properly back up a circuit designed for 12V.
- Sealed lead-acid batteries self-discharge on the shelf; the ELK-0675's storage capacity is rated in months, so spares held in inventory should be tracked and rotated rather than left indefinitely.
Reach for the ELK-0675 when you're replacing or stocking backup power for a 6V-rated alarm panel or access control power supply — not as a general-purpose substitute for the 12V batteries used in most standard alarm panel installs.
