ANSMANN 1311-0035 Li-ion Rechargeable Batteries, Micro AAA Type 500, 4x with Box

For professionals who rely on wireless devices daily—think field technicians, photographers, or medical staff—the ANSMANN 1311-0035 Li-ion rechargeable batteries in AAA size deliver constant 1.5V output without the voltage sag of NiMH cells. Each battery charges directly via its integrated USB-C port, eliminating the need for a separate charger, and the included storage box keeps the set of four organized and protected.

Why choose it

These batteries maintain a rock-solid 1.5V from full charge to empty, so your devices perform consistently—no more dimming flashlights or slowing motors as the battery drains. The built-in USB-C port means you can top them up anywhere: from a laptop, power bank, or wall adapter. With up to 1000 cycles, they replace hundreds of disposable alkalines, cutting waste and long-term cost. Built-in safety electronics protect against common hazards, making them safe for sensitive equipment.

Ideal use cases

• High-drain devices: wireless microphones, active styluses, medical instruments, and LED headlamps.
• Everyday electronics: remote controls, computer peripherals, toys, and clocks where stable voltage matters.
• Travel and field work: charge via USB-C from any power source, no dedicated charger needed.
• Backup power: keep a set ready in the included box for emergencies.

Good to know

Each battery charges independently; a full charge takes about one hour. The LED indicator shows charging status at a glance. The storage box protects the batteries from short circuits and physical damage when not in use. Note that these are 1.5V Li-ion cells, not 1.2V NiMH, so they are compatible with devices designed for standard AAA voltage. Do not use in devices that require 1.2V specifically.
