Can I replace NiCd with NiMH?
Sometimes—but many emergency light charging circuits are designed around NiCd. For best compatibility, match the original chemistry unless your fixture documentation explicitly allows NiMH.
How do I confirm I’m ordering the right pack?
Match voltage (2.4V), chemistry (NiCd), connector type, and physical dimensions/layout of the pack in your fixture.
Do I need to charge it before testing?
Yes. After installation, allow the fixture to charge (often 24 hours for a full charge) and then run a test.
How should I dispose of the old battery?
NiCd batteries should be recycled properly. Use a local battery recycling program or approved drop-off location.
How to Match Your 051426 Battery (Fast, No-Guess Guide)
- Read the label on the old pack: confirm it says 2.4V and note the 1400 mAh rating.
- Check the connector: quick-disconnect/faston style vs. plug. Match what you have.
- Measure the pack: length/width/height and cell layout (commonly a 1×2 configuration).
- Confirm wire length and polarity: take a quick photo before disconnecting anything.
- After install: allow a full charge cycle, then press the test button to verify runtime.
Common Signs the Battery Needs Replacement
- Unit won’t stay lit during a test
- Very short runtime
- Swollen pack, corrosion, or heat damage
- Fixture shows “charging” but fails under load
If you’re unsure, send a photo of the old battery label and connector style—matching the connector and dimensions prevents ordering the wrong pack.
