To get the most from your tail, you should use Lithium batteries, which last 8 x longer.. They also have the power to deliver the energy that the Tail needs for some of its bigger moves. We sell them in different numbers, depending on which Tail you have.
Baby Tails (inc Bunnies and Huskies) need one pack of 4 x AAA batteries, and Original / XL and Super XL Tails need two packs of 4 x AAA batteries.
Rechargeable batteries (NiMH) are great too if you want to use those.
Dont mix new and old batteries in the Tail. Or use different kinds of batteries in the Tail at the same time. This may damage the clever stuff inside. If youre not using your tail for a long time, its best to remove the batteries from the holders.
