CR1216 vs. CR1220 vs. CR1225

CR1216, CR1220, and CR1225 batteries are similar but differ in size and performance:

• CR1216 batteries measure 12.5 x 1.6 mm, with a capacity of around 25 mAh and drain currents similar to CR1220 batteries.

• CR1220 batteries measure 12.5 x 2.0 mm, with a capacity of 35-40 mAh and somewhat lower drain currents than CR1225 batteries.

• CR1225 batteries measure 12.5 x 2.5 mm, with a capacity of approximately 50 mAh and somewhat stronger discharge currents than CR1220 batteries.

While some battery compartments for CR1220 batteries may accommodate larger CR1225 batteries or smaller CR1216 batteries, caution is advised to avoid damaging the device.

For instance, in credit card-sized devices, even a small height difference of 0.5 mm between CR1220 and CR1225 batteries or 0.4 mm between CR1220 and CR1216 batteries can lead to warping, shape alteration, and malfunction.

In summary, it's important not to substitute CR1220 batteries with similarly sized button/coin cell batteries.
