Batteries and Chargers

How to Choose the Perfect Batteries & Chargers

When selecting batteries, start by matching chemistry and size to your device’s requirements—whether that’s high-capacity 18650 or 21700 cells for powerful torches, AA/AAA NiMH or lithium for headlamps, or specialty CR123A/16340 for compact lights. Consider capacity (mAh) versus discharge capability (A): higher-capacity cells deliver longer runtimes, while high-drain devices demand cells rated for sustained currents of 10 A or more. Decide between protected cells, which include built-in safety circuits, or unprotected options for maximum capacity in weight-sensitive setups.

For chargers, look at channel count and charge management. Single-bay chargers suit individual cell top-ups, while multi-channel units let you charge sets of batteries simultaneously. Smart chargers with microprocessor control optimise charge profiles, prevent over-charging, and offer temperature monitoring—essential for cell longevity and safety. USB-powered or USB-C models provide on-the-go flexibility, whereas mains chargers deliver faster charging currents. Finally, clear LED or LCD indicators and automatic cut-off features help you know when cells are ready, so you’re never left guessing.
