JCB AA LR6 Ultra Alkaline Batteries 10 Pack

The JCB AA LR6 is a 1.5V ultra alkaline battery sold in a 10-pack format. Each cell uses alkaline chemistry to deliver stable voltage across the discharge curve, making these batteries suitable for high-drain devices like digital cameras, gaming controllers, wireless keyboards and remote controls that draw power frequently or continuously.

Designed for both household and professional use, the 10-pack format provides replacement stock for multi-device households or workplaces without needing frequent re-ordering. JCB rates these ultra alkaline cells to last up to ten times longer than standard zinc-carbon batteries in equivalent applications, though actual runtime depends on the specific device and usage pattern. The standard AA (LR6) size fits the majority of battery-operated consumer electronics sold in the UK market.

The pack measures 180mm wide by 117mm high with a 5mm depth profile and weighs 230g including the blister card. Each cell delivers 1.5V nominal voltage under load and maintains voltage stability better than zinc-carbon alternatives as the cell discharges, reducing the risk of device malfunction or data loss in critical applications. The alkaline formulation also performs more reliably at lower temperatures than zinc batteries, making these cells suitable for outdoor devices like torches and trail cameras during winter months.

How long do these batteries last compared to rechargeable AA cells?

Alkaline AA batteries typically provide higher initial capacity than rechargeable NiMH cells (around 2500-3000mAh vs 1900-2500mAh), but rechargeables can be used hundreds of times. For devices used infrequently, alkaline cells are often more practical. For daily-use devices like wireless keyboards or game controllers, rechargeable cells become more cost-effective over time.

Can these be used in smoke alarms?

Yes. AA alkaline batteries are suitable for smoke alarms, though most UK smoke alarms use 9V PP3 batteries or sealed lithium cells. Check your specific alarm model before purchasing.

What's the shelf life?

Alkaline AA batteries typically retain 80-90% of their charge after 5-7 years in storage at room temperature. Store in a cool, dry location away from direct heat or metal objects that could short-circuit the terminals.

Are these batteries mercury-free?

Modern alkaline batteries sold in the UK are mercury-free and cadmium-free, complying with the EU Battery Directive. Dispose of spent batteries at designated recycling points rather than general waste.
