We go thru batteries like water, and made the switch about two years ago to using rechargeables as often as possible.
Here’s a great deal: Amazon has eneloop XX 2500mAh Typical / 2400 mAh Minimum, High Capacity, 8 Pack AA Ni-MH Pre-Charged Rechargeable Batteries for just $30.24, regularly $46.99, with FREE shipping.
This is the lowest ever price, per the Amazon Price Tracker.
You will need a charger, too, if you don’t already have one.
Hurry – because there are only a handful of these left at this price.
