Great value for the money, easy to use and charge fairly quickly. ### ⭐⭐⭐⭐⭐ Works great in my Kindle fire stylus. Using it right now! *by T***G on July 31, 2026* Using this nice AAAA battery in my Kindle fire stylus right now! ### ⭐⭐⭐⭐⭐ Good for NiMH batteries, but look for Lithium Ion batt's for best performance today *by F***F on April 6, 2025* Nice small form factor charger set with four AAAA batteries included. This is a NiMH model. Better than NiCd but not as good as the newer Lithium Ion technology. NiMH imseems to be the most common battery tech currently due to its product maturity and value over the oldest NiCd tech, which only stays rechargeable for a year or two if you're lucky. The total voltage is slightly less per battery than "normal" non-rechargeable Alkaline batteries so they will not last long in power hungry devices. If your standard Alkaline batteries lasted a year in the device, expect NiMH to last maybe 30-90 days before recharge. ## Frequently Bought Together - Tectra 450mAh AAAA Batteries, 4-Pack AAAA Rechargeable Ni-MH Batteries with AA AAA AAAA Ni-MH Universal Smart Battery Charger for Surface Pen Active Stylus - Duracell AAAA 1.5V Ultra Photo Alkaline Batteries, 2 Count Pack, AAAA 1.5 Volt Alkaline Battery, Long-Lasting for Cameras, Glucose and Blood Monitors, and More - ANVOW AAAA Batteries, Rechargeable AAAA Batteries for Surface Pen, Rechargeable AAAA Battery for Active Stylus, Ni-MH 1.2V 400mAh with Storage Box, 4 Count --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/326420789-450mah-aaaa-batteries-4-pack-aaaa-rechargeable-ni-mh-batteries](https://www.desertcart.us/products/326420789-450mah-aaaa-batteries-4-pack-aaaa-rechargeable-ni-mh-batteries) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-17*
