Compact Universal Battery Tester

A compact battery-checking tool for common removable batteries used around camp kits, torches, remotes and small household gear.

Use it as a simple pre-trip check for AA, AAA, C, D, 9V and compatible button-cell batteries before packing spare cells.

• Checks common removable battery formats including AA, AAA, C, D, PP3/9V, 1.5V and button-cell batteries.
• Compact analogue-style tester for quick go/no-go checks.
• No charging function: this item tests batteries only.
• Not intended for automotive batteries, deep-cycle batteries, lithium power packs, medical equipment or safety-critical diagnostics.

Keep readings conservative and replace batteries when performance is uncertain.
