GP Button Cell Batteries

No, an LR44 is a 1.5V alkaline cell while a CR lithium coin cell is 3.0V, so fitting one would give the device twice the voltage it should get. AG13 and A76 are equivalent codes for GP's LR44 cells, the 656.203UK and 656.206UK. GP's CR coin cells, such as the CR2032 656.264UK, are rated 3.0V, so replace an LR44 with another LR44 or an equivalent code.

An LR41 can replace any 1.5V alkaline button cell of the same size sold under one of its equivalent codes. GP's LR41 replaces 92, G3A, GP192, GP92, L736 and V36A, and GP sells it ten to a pack as the 656.207UK. If the old cell in your device carries one of those markings, the LR41 is the like-for-like replacement.

Lithium coin cells power small devices such as clocks, calculators and remote controls for car alarms, and serve as backup batteries. GP's 3.0V lithium button cells, such as the CR2032 656.264UK and CR1220 656.252UK, are suitable for those uses. Read the code on the old cell, for example CR1616 or CR2430, and fit the same size.

No, not as a like-for-like swap unless the device maker allows it, since a CR2025 is thinner than a CR2032. Under IEC 60086 naming, the first two digits give the diameter and the last two the thickness, so the two cells have the same diameter; fit the code the device asks for. GP sells them separately, the 656.262UK CR2025 and the 656.264UK CR2032, each in a pack of five and rated 3.0V.

It depends on the cell, so check the pack quantity for the cell size you need. GP lithium sizes such as the CR1220, CR2032 and CR2430 come five to a pack. The LR44 is sold as the 656.203UK and in a ten-pack as the 656.206UK, and the LR41 656.207UK is a ten-pack.
