Codes that mean the same battery
| Code | Fits? |
|---|---|
| DL2430 | Yes — same cell |
| ECR2430 | Yes — same cell |
| KCR2430 | Yes — same cell |
| BR2430 | Yes — same cell |
| SB-T13 | Yes — same cell |
Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| CR2450 | Same diameter, 5.0 mm tall. Too thick for a CR2430 compartment. |
| CR2032 | Only 20 mm across. It rattles sideways in a 24.5 mm holder and may not contact at all. |
The CR2430 is a primary cell and must never be put in a charger. Charging a sealed primary battery builds gas pressure inside a can with no vent designed for it, which is how they rupture or catch fire. Rechargeable look-alikes exist for several sizes and carry different codes — check the code, not the shape.
Where it turns up
- Toyota and Lexus smart key cards
- Talking and singing greeting cards
- Medical alert pendants
- Watch modules in larger cases
Energizer rates it at 320 mAh; Panasonic and Renata publish 270–290 mAh.
