Rechargeable battery MediaRange MRBAT161 AA Lithium-Ion 18g

MediaRange USB-C rechargeable Li-Ion batteries provide a sustainable, high-performance replacement for disposable alkaline cells. These 1.5V batteries are designed for everyday electronic devices and integrate a USB-C charging port to eliminate the need for a separate charger. With a lifespan of up to 1200 charge cycles and built-in safety protections, they deliver stable power while reducing battery waste and long-term costs.

Advantages

USB-C charging makes recharging simple and compatible with common power sources. The batteries support up to 1200 charge cycles, offering a long service life compared with single-use cells. Fast charging fully restores capacity in approximately 2 hours, and an LED indicator shows charging status — blinking during charge and steady when complete. Integrated safety features protect against overvoltage, short circuit and overcharging. A 4-to-1 USB charging cable is included for charging multiple batteries at once.

Key specifications

• Nominal voltage: 1.5 V
• Charge cycles: up to 1200
• Charging interface: USB-C
• Full charge time: approximately 2 hours
• Safety: overvoltage, short-circuit and overcharge protection
• Indicator: LED (flashing while charging, steady when charged)
• Accessories: 4-to-1 USB charging cable included

How to use

Insert the MediaRange rechargeable battery into the device as you would a standard AA/AAA cell (match size and polarity). To recharge, connect the battery's USB-C port to a compatible USB power source using the provided cable; multiple batteries can be charged simultaneously with the 4-to-1 cable. The LED will flash during charging and remain steady when fully charged. Avoid using the battery in devices that explicitly require non-rechargeable cells and follow device manufacturer recommendations for battery type and installation.

Recommendations

Store batteries in a cool, dry place and avoid prolonged exposure to high temperatures. For maximum lifespan, do not leave batteries continuously connected to power after the LED indicates full charge. Replace batteries when you notice reduced runtime or performance.
