Rechargeable Batter 4-pack for only $13
Whether you are on the go or simply at home playing around with your gadgets, having a set of spare batteries is always a good idea. But don't spend a ton on those single use batteries. Instead it would be better to opt for the Eneloop Rechargeable NiMH 'AAA' Battery. These batteries last longer on a single charge compared to other rechargeable batteries available. And they can be charged for up to 1000 cycles, which means that you won't be running out of spares for a long while. And even if you don't use them all that often, they have a long l;ife. A 4-pack costs only $13 from Dick Smith.
