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.
