Frequently Asked Questions

What is the difference between alkaline and lithium batteries?

Alkaline batteries are a cost-effective, general-purpose choice with a 1.5V rating, while lithium batteries are lighter, offer higher energy density, and perform much better in extreme temperatures and high-drain devices.

How long do rechargeable batteries last?

The lifespan of rechargeable batteries typically ranges from two to seven years and can endure hundreds or over a thousand recharge cycles, depending on the chemistry and how often they are used.

Can I use rechargeable batteries in any electronic device?

Generally, yes, but the slightly lower nominal voltage of NiMH rechargeable batteries (1.2V vs 1.5V for alkaline) can sometimes cause highly voltage-sensitive devices to give a 'low battery' warning prematurely.

What does “mAh” mean on a battery?

'mAh' stands for milliampere-hour, and it is a measure of the battery’s capacity, indicating the amount of energy it can store and how long it can power a device before needing to be recharged or replaced.

How should I store unused batteries safely?

Store unused batteries in their original packaging, or a suitable plastic container, in a cool, dry place at room temperature, ensuring terminals do not contact metal objects to prevent short circuits.

Are lithium batteries safe for everyday electronics?

Yes, lithium batteries are generally safe and are used daily in millions of devices, but they must be handled, charged, and disposed of correctly, as improper use presents a fire risk.

Can I mix old and new batteries together?

No, you should never mix new and old batteries, or different types, as it can cause over-discharging in the older cell or uneven power distribution, which reduces overall life and increases the risk of leakage.

How do I recycle used batteries properly?

Used batteries should be recycled by taking them to a designated battery drop-off point at a local recycling centre or a retailer, often after taping the terminals of lithium cells for safety.

Which battery type is best for cameras and toys?

High-drain devices like digital cameras and modern toys are best powered by high-performance lithium batteries or NiMH rechargeable batteries for consistent, long-lasting performance.

Why do batteries sometimes leak or swell?

Battery leakage, which is often potassium hydroxide in alkaline cells, usually occurs when a battery is fully depleted, overcharged, aged, or exposed to excessive heat, causing internal pressure to build up and rupture the casing.
