AAA is the type it takes. The only difference in different kinds of AAA batteries is how long they'll last. Some batteries last longer than others. (I usually use Duracells - I don't work for them, they just seem to be a good price for the quality.)
Types are AAA, AA, C, D, etc. If it takes AAA, it'll work with any AAA - even if you mix manufacturers. (If you're using rechargeables, don't do that - use batteries from the same lot.)
