Short Answer: I recommend Pickle Power Ni-MH rechangeable AAAA batteries.
Yes, rechargeable AAAA batteries do exist.
AAAA batteries (or quadruple As) are most often used in small devices such as laser pointers, LED penlights and small headphone amplifiers.
AAAA batteries are not common. However, rechargeable AAAAs do exist in two forms:
- NiCads (Nickel Cadmium) rechargeables
- NiMH (Nickel-Metal Hydride) rechargeables
NiMH have a higher energy capacity and are less toxic than NiCads (cadmium is a potent environment toxin).
Here are all the other commonly available rechargeable AAAA available:
Bought the Anwow set with charger from Amazon. Worked for about 6 months. At first, a freshly charged battery lasted for about a month in my stylus. Now, I am lucky if I can get 3 days use before getting “battery low” warnings. Which basically means these batteries lasted through a maximum of THREE recharge cycles each using the supplied charger. Either the batteries are junk, or the charger is junk because it killed the batteries, or BOTH.
Odec battery is best. I have used it on my camera and performance is well.
