GP Batteries

Ultra+ is the longer-lasting of the two alkaline lines. Ultra+ batteries, such as the 656.001UK AA and 656.000UK AAA four-packs, last around 30% longer than the standard Ultra range and suit digital cameras and MP3 players. Ultra, such as the 656.010UK AA, is formulated for power-hungry toys, torches, portable radios and smoke alarms.

Greencell batteries are GP zinc chloride cells for low to medium drain devices. Uses include clocks, remote controls, LED torches, calculators and portable radios. Sizes here include the 656.050UK AA, 656.053UK AAA, 656.055UK C, 656.057UK D and 656.060UK PP3. For high current over longer periods, GP formulates its Ultra alkaline range instead.

Use the type the alarm maker specifies, and where a 9V or AA lithium cell is allowed, it outlasts alkaline. The GP 656.331UK PP3 and 656.334UK AA lithium batteries suit smoke and fire alarms, lasting 2-5 times longer than ordinary alkaline cells with a low self-discharge rate. GP Ultra alkaline cells such as the 656.020UK PP3 are also formulated with smoke alarms in mind.

ReCyko+ NiMH batteries can be recharged hundreds of times, stay charged when not in use and last longer than alkaline batteries. The range here covers AA at 1300mAh, 2100mAh and 2600mAh and AAA at 700mAh and 950mAh, sold in four-packs.

Match the code printed on the old cell exactly, such as CR2032 or CR2025, because the code sets the size. GP lithium coin cells here include the CR1220, CR1616, CR1620, CR1632, CR2025, CR2032, CR2430 and CR2450, all rated 3.0V, and most come in packs of five.

The GP LR44 alkaline button cell is also coded AG13 and A76, so a device calling for any of those codes takes the same cell. It is sold as the 656.203UK and in a pack of 10 as the 656.206UK, both at 125mAh. The smaller LR41 656.207UK replaces 92, G3A, GP192, GP92, L736 and V36A cells.

GP zinc air hearing aid batteries here include the PR48 (656.785UK), the PR41 (656.788UK) and a 75mAh pack (656.782UK), each at 1.4V and supplied six to a plastic dispenser. GP pairs its ZA13 code with PR48 and ZA312 with PR41, so either marking on your old battery identifies the cell. GP designs them to hold a stable voltage for delicate devices such as hearing aids.

They are GP High Voltage Alkaline cells for small devices such as car alarms and lighters. The 23AE (656.006UK single, 656.007UK five-pack), the 27A (656.624UK single, 656.625UK five-pack), the 11A (656.304UK) and the 4LR44 (656.306UK) are suitable for car alarms, lighters and some cameras, built to perform over a wide range of operating temperatures.

A CR123A is a 3V lithium photo cell. GP makes the 656.339UK CR123A and the 656.343UK CR2, both designed for photographic cameras, with extra long life and supplied one per blister. Match the code on the device or the old cell before you buy, because a CR123A and a CR2 are different sizes and are not interchangeable.
