Description
The JCB Bumper pack contains 18 AA alkaline batteries (LR6 designation, 1.5V nominal voltage), packaged in two rows of nine cells for easy dispensing. Each cell uses alkaline manganese dioxide chemistry, providing higher energy density than zinc-carbon alternatives and a shelf life of approximately 5-7 years when stored at room temperature.
AA alkaline batteries suit medium-drain devices such as remote controls, wall clocks, wireless keyboards and mice, battery-operated toys, torches and LED headlamps. The 18-cell count is sized for households or workplaces where multiple devices draw from the same battery type, reducing the frequency of restocking trips. The bumper pack format typically offers lower cost per cell than smaller 4-packs or 8-packs.
JCB positions its Super Alkaline range as a mid-tier option between budget zinc-carbon cells and premium lithium primaries. The cells carry no-leak guarantees for a defined period (check packaging), meaning that if a cell leaks and damages a device during normal use within the guarantee window, JCB will repair or replace the device. The batteries perform across a temperature range of approximately -10°C to 50°C, with reduced capacity below 0°C as is typical for alkaline chemistry.

Frequently Asked
What's the difference between AA and AAA batteries?
AA and AAA refer to cell size. AA cells are larger (approximately 50mm long, 14mm diameter) and hold more energy. AAA cells are smaller (44mm long, 10mm diameter) and hold less. Devices are designed for one or the other — check your device's battery compartment label.
Can alkaline batteries be recharged?
No. Standard alkaline batteries like these JCB cells are single-use primaries. Attempting to recharge them can cause leakage, rupture or fire. If you need rechargeable AA cells, look for NiMH batteries marked as rechargeable.
How long do AA alkaline batteries last?
Runtime depends on the device's current draw. In a low-drain wall clock, a single AA alkaline might last 12-18 months. In a high-drain digital camera, the same cell might last only 30-60 minutes of continuous shooting. Torches, wireless mice and remote controls typically fall between these extremes.
What does the 8X claim on the packaging mean?
JCB claims these cells deliver up to eight times more power than standard zinc-carbon batteries in certain applications. This comparison is against older zinc-carbon technology, not against other alkaline brands. The improvement is most visible in medium- to high-drain devices where zinc-carbon cells drop voltage quickly.
