Description
The Panasonic AA LR6 is a 1.5V zinc carbon battery sold in a 10-pack. Zinc carbon chemistry provides a lower-cost alternative to alkaline cells for devices that draw power intermittently or at low rates, such as wall clocks, remote controls, kitchen timers, small torches and basic handheld toys.
Designed for household, office and classroom environments where multiple devices need inexpensive replacement batteries, the 10-pack format suits users stocking a drawer or cupboard with spares. The LR6 designation indicates AA size with a standard 14.5mm diameter and 50.5mm height, fitting any device that takes AA cells. Zinc carbon cells deliver steady voltage under low-drain conditions but are not recommended for high-drain applications like digital cameras, gaming controllers or motorised toys that require alkaline or lithium chemistry.
Each cell weighs approximately 14g, making the full 10-pack portable and easy to store in a utility drawer, toolbox or office supply cabinet. The Panasonic Heavy Duty range positions these batteries as a budget-conscious option where the cost per battery matters more than total runtime, and where devices are used infrequently enough that shelf life is not a primary concern. The cells carry no added mercury, lead or cadmium.

Frequently Asked
What's the difference between zinc carbon and alkaline batteries?
Zinc carbon cells like the LR6 cost less but have lower capacity and shorter runtime than alkaline batteries. They work well in low-drain devices (clocks, remote controls) but are not suited to high-drain applications (cameras, gaming controllers, motorised toys) where alkaline or lithium chemistry is needed.
How long do these batteries last in a wall clock?
Runtime depends on the clock's power draw, but a typical quartz wall clock drawing 10-20 microamps can run for several months on a zinc carbon AA. Devices with LED backlights or alarms will drain the cells faster.
Can these be used in smoke alarms?
No. Smoke alarms require alkaline or lithium AA cells due to their periodic high-drain test pulses and the need for long shelf life. Zinc carbon batteries lack the capacity and reliability needed for safety-critical devices.
Are these rechargeable?
No. Zinc carbon batteries are single-use disposable cells. Attempting to recharge them can cause leakage or rupture. For rechargeable AA cells, look for NiMH (nickel-metal hydride) batteries rated at 1.2V.
