It runs on 2 AA batteries.
According to Energizer, they claim that their rechargeable AA batteries will hold their charge for up to 1 year. How long a battery lasts is also dependant on how much it is used.
Which brand of AA batteries lasts the longest
Wii remotes run on 2 AA batteries but if you can get a pair of recharable batteries then yes you would need to charge them. (Pick your brand carefully, some batteries run out fast!)
Energizer lithium AA batteries have a minimum of a 10 year shelf life,they are considered the best.
The AX-Synth does not recharge the batteries. You have to get an external AA Ni-MH charger.
Yes that the Quick Charge II Instant Cell Phone Charger needs 2 AA batteries.
Rechargable batteries will not last as long as normal AA's, but, of course, can be recharged, and should last over a year.
i depends on the toy
You'll have to get your batteries replaced. Some take AA batteries, but you may have to call the manufacturer if you have a propietary battery.
