What battery can replace CR2430?
Is there a difference ic a cr1620 and cr2016? You bet. They are physically a different size. CR1620s are smaller.
carbon-monofluoride lithium battery
Electrically there is no difference except the larger cell will have more capacity but the same voltage. The physical numbers say the 2016 will not fit in the 1616 socket; it is too large.
CR2430 battery is non-rechargeable lithium 3.0 volts battery with a typical capacity of 270-300 mAh and physical dimensions of 24.5 x 3.0 mm. For short – do NOT replace the CR2450 battery with the CR2430 battery, except perhaps in utmost urgency at your own risk!
Can a CR2430 replace a CR2450?
3V Energizer CR2450 Lithium Coin Cell-Replaces Duracell DL2450
Output voltages of these batteries are the same for the same chemistry types. The CR2450 battery relies on the same storage technology as the CR2032 type. But since the CR2430 batteries are wider, they cannot be used interchangeably with CR2025 and CR2032 batteries.
Are CR2450 and CR2032 interchangeable?
Are CR2430 and CR2450 the same?
If your device uses a CR2430 battery, it can be replaced with an ML2430 battery, but don’t expect it to last a long time. LiR2430 battery features lithium-ion chemistry, with a nominal voltage between 3.2 and 3.7 volts, depending on the actual chemistry.
