GSUIVEER 3.6V 900mAh Ni-Cd Exit Sign Battery (2 Pack)
Voltage: 3.6V; Capacity: 900mAh; Chemistry: Nickel-Cadmium. This pack is designed for exit-sign emergency lights and supports models including Unitech 6200RP and OSA230 families. Best for smaller signs and budget-conscious projects. Limitation: Ni-Cd chemistry has lower energy density than some Ni-Md or Li systems, which may affect runtime in high-demand signs.
Mighty Max Battery Exit Sign Battery 6V 4.5Ah Backup – 6 Pack
Voltage: 6V; Capacity: 4.5Ah; Type: SLA. Pack includes six batteries, suitable for larger exit signs or multiple units. Best for high-usage facilities requiring longer backup. Caution: This is a sealed lead acid battery; proper handling and ventilation are necessary during charging and disposal.
GLESOURCE 3.6V 900mAh Ni-Cd Exit Sign Battery (10 Pack)
Voltage: 3.6V; Capacity: 900mAh; Chemistry: Ni-Cd. Replacement for models including Exitronix 10010037, Unitech LEDR-1, and OSA230. Best for bulk stocking across facilities with many units. Limitation: Large pack size may be unnecessary for smaller sites; ensure compatibility with your specific model.
GSUIVEER 9.6V 900mAh Exit Sign Battery (2 Pack)
Voltage: 9.6V; Capacity: 900mAh; Chemistry: Ni-Cd. Designed to fit higher-voltage exit-sign configurations and compatible with models listed in the product details. Best for signs that require more voltage for reliable operation. Caution: Confirm model compatibility before purchase due to the broader voltage range.
NEAFAZA 5 Pack 1.2v 900mAh Ni-CD AA Exit Sign Battery
Voltage: 1.2V; Capacity: 900mAh; Chemistry: Ni-Cd. Replacement for legacy 1.2V AA-based exit-light systems and compatible with multiple brands. Best for budget-conscious projects requiring many replacements. Limitation: AA-format batteries may require more frequent replacement in heavily used signs compared to higher-capacity packs.
NEAFAZA 1.2v 900mAh Ni-CD AA Exit Sign Battery Replacement (2 Pack)
Voltage: 1.2V; Capacity: 900mAh; Chemistry: Ni-Cd. Replacement pair for Unitech AA900mAh 1.2V configurations and similar models. Best for two-pack needs; ensures a ready spare. Limitation: Some models may require different terminal sizing or connectors, so verify fit before ordering.
Buying Guide
Key considerations when choosing batteries for emergency exit signs:
- Voltage compatibility: Match the sign’s required voltage (1.2V AA, 3.6V, 4.8V, 9.6V, or 6V) to avoid underpowered operation or damage.
- Chemistry: Ni-Cd is common for older or budget-friendly exits; SLA batteries offer longer life for higher-demand signs. Assess maintenance needs and disposal requirements.
- Capacity needs: Higher mAh values extend backup time but may not fit compact sign enclosures. Balance runtime with size constraints.
- Form factor: Ensure the battery pack’s shape (AA, two-pack, 6V block) suits your specific model’s terminals and compartment.
- Replacement cadence: Signs with frequent outages benefit from higher-capacity packs; plan for periodic checks and replacements.
- Compatibility: Use listed compatibility or model numbers to reduce the risk of improper fit and electrical issues.
FAQ
- Q: What type of battery is best for emergency exit signs? A: Ni-Cd and SLA batteries are common; choose based on your sign’s voltage, capacity needs, and enclosure space.
- Q: How do I know the right voltage for my exit sign battery? A: Check the model’s documentation or labeling on the current battery; match the voltage exactly to avoid damage.
- Q: Is a higher capacity battery always better? A: Not necessarily. It extends runtime but may not fit the sign’s compartment or electrical charging limits.
- Q: Can I mix brands for replacement batteries? A: It’s best to use the same chemistry and close capacity/voltage to maintain reliable performance and charging behavior.
- Q: How should I dispose of used exit-sign batteries? A: Follow local regulations for battery recycling and disposal; many facilities accept Ni-Cd and SLA batteries.
- Q: Do these batteries require special charging conditions? A: Some chemistries, particularly Ni-Cd, benefit from proper charging procedures; refer to manufacturer guidelines for charging.
