AA - Rechargeable

1.2V / 1000mAh rechargeable NiMH battery with protection circuit. Use in place of AA batteries if you want the convenience of recharging your batteries instead of replacing with new when power gets low. Use the supplied USB/micro-USB cable to connect to a common 5V USB charging block or computer USB port to charge. Keep a spare around so they can be switched out when needed, instead of having to wait for a recharge.
