GSUIVEER 3.6V 900mAh Ni-Cd Exit Light Battery Pack (2 Pack)
The 2-pack GSUIVEER battery set is designed for 3.6V exit-sign applications. It uses Ni-Cd chemistry with 900mAh capacity suitable for models such as Unitech 6200RP and OSA230 family. This option is best for technicians replacing multiple units or systems that require standard 3.6V Ni-Cd backups. A clear caution: Ni-Cd cells have lower energy density than some modern chemistries and can be sensitive to long-term storage if not cycled periodically. Choose this if your exit sign uses 3.6V Ni-Cd packs and you need a cost-effective, ready-to-install solution.
Mighty Max Battery ML4-6 – 6V 4.5Ah SLA AGM Battery
The Mighty Max ML4-6 is a 6V, 4.5Ah Sealed Lead Acid (SLA) rechargeable battery. It is a maintenance-free option with a compact footprint, suitable for higher-demand exit signs or longer runtimes. This battery is best for larger or more energy-hungry emergency-light installations where a steady, reliable 6V backup is required. Caution: This is a larger format than some 3.6V packs, so verify space and terminal type before installation. Best for installations needing higher capacity at 6V.
GSUIVEER 9.6V 900mAh Ni-Cd Exit Sign Battery (2 Pack)
This 9.6V pair provides 900mAh capacity in Ni-Cd chemistry, designed to boost higher-voltage exit-light systems and models like Unitech ELB-B003/B004 and Lithonia ELB variants. It’s best for signs that operate at 9.6V with a need for reliable backup power and quick replacement without rewiring. One limitation: Ni-Cd chemistry can develop memory effects if stored improperly; ensure complete discharge and recharge cycles per device guidelines. Choose this for 9.6V applications needing solid backup performance.
Mighty Max Battery Exit Sign Battery 6V 4.5Ah Backup – 6 Pack
This listing offers a 6V 4.5Ah SLA backup in a 6-pack, suitable for multiple exit signs or larger installations needing parallel replacement options. It shares the same SLA/AGM stability as the ML4-6 but is intended for bulk deployments. Best for facility managers replacing several units at once. Limitation: Not including mounting hardware or wiring accessories; order those separately if needed. Preferred for bulk, high-usage environments.
GLESOURCE 3.6V 900mAh Ni-Cd Exit Sign Battery (10 Pack)
GLESOURCE’s 10-pack of 3.6V 900mAh Ni-Cd batteries offers a practical bulk option for technicians handling frequent replacements across multiple signs. It covers a wide range of models including Unitech LEDR-1, 6200RP, OSA230, and more. Best for service teams that need quick, scalable replacements. Caution: bulk packs may include a mix of units; verify compatibility with your specific model before installation.
GLESOURCE 3.6V 900mAh Emergency/Exit Light Battery (Lithonia, Unitech, Interstate, More) 2 Pack
This 2-pack from GLESOURCE targets multiple brand models, including Lithonia EU2C M6 and Interstate ANIC1566. It’s positioned as a flexible 3.6V Ni-Cd replacement suitable for a variety of common exit-light setups. Best for shops stocking a broad mix of brand models. Limitation: 3.6V Ni-Cd chemistry may be less energy-dense than newer chemistries; ensure compatibility with your device’s charging circuitry and replacement interval.
Fulpower 5-Pack 3.6V 900mAh Ni-Cd AA Batteries
Fulpower’s 5-pack provides direct 3.6V Ni-Cd AA replacements for popular exit-light models like Exitronix 10010037 and Unitech LEDR-1. This option emphasizes compatibility and cost-effectiveness for installations relying on 3.6V packs. Best for small to medium facilities with several signs sharing the same 3.6V battery spec. Limitation: 5-pack may require paired units for devices with higher current draw; confirm your unit’s exact capacity needs before replacing many signs at once.
Buying Guide
Key considerations when choosing an exit-light battery:
- Voltage and chemistry: Match the device’s voltage (3.6V, 9.6V, or 6V) and the chemistry (Ni-Cd vs SLA/AGM) to ensure compatibility and safe charging.
- Capacity vs runtime: Higher mAh generally means longer runtime between charges. For signs with frequent power outages, a higher-capacity option is preferable.
- Form factor and terminals: Confirm the battery size, shape, and terminal type (F1, for example) to fit your housing and wiring harness.
- Bulk vs single packs: Bulk packs (like 10-pack or 6-pack) suit service teams with many units, while smaller packs fit single replacements.
- Lifecycle and maintenance: Ni-Cd batteries offer robustness and fast recharge but shorter energy density; SLA/AGM batteries provide maintenance-free operation with deeper discharge recovery.
- Compliance and safety: Ensure replacements comply with local electrical codes and the exit-light manufacturer’s specifications.
Common Questions
- What battery chemistry should I choose for exit signs? – Ni-Cd is common for direct replacements and simple charging circuits; SLA/AGM can offer higher capacity and longer life in some setups.
- Can I mix different brands in the same sign? – It’s best to use identical voltage and chemistry in a sign to avoid charging imbalances.
- How do I know the right voltage for my exit sign? – Check the label on the existing battery or the device’s manual for the required voltage (3.6V, 6V, or 9.6V).
- Are bulk packs more cost-effective? – Yes, bulk packs save per-unit cost and reduce restocking frequency for multi-unit installations.
- Do these batteries require special disposal? – Follow local regulations for battery recycling; Ni-Cd and SLA batteries have specific handling guidelines.
- What should I do if the replacement doesn’t fit? – Verify model compatibility and verify connector positions; contact the supplier for alternatives if needed.
