I recommend *by C***G on July 17, 2026* Does the job and can't get any more accurate than this old style battery tester.. I would buy again if needed ### ⭐⭐⭐⭐ Both battery testers worked *by A***. on July 22, 2026* These battery testers were a great price for two of them. It had mixed reviews, so I was hoping at least one worked if I had a problem with that, but they both worked. I like that you can test many different batteries. It was easy to work. It found the dead battery I kept mistakingly trying to use. On the battery testers, I outlined the battery shape with gold and the other one silver so if one dies, I’ll know which one stopped working plus it makes it easier for my family to see some of them have glasses, and sometimes have a hard time seeing things like that. Some people said that theirs didn’t work for very long. I hope mine does. I’ve only been using it for a week. I gave it a 4 stars just because I don’t know how well, or how long they will last. ## Frequently Bought Together - 2 Pack Battery Tester, Universal Battery Checker for AA/AAA/C/D / 9V / 1.5V Button Cell Batteries Household Battery Life Level Testers Power Monitor Meter (Requires No Battery for Operation) - Tenergy T-333 Universal Battery Tester, LCD Display, Cell Checker, Multi-Purpose Small Battery Tester, for AA, AAA, C, D, 9V, CR123A, CR2, CRV3, 2CR5k CRP2, and Button Cell Batteries - Amazon Basics AAA Alkaline High-Performance Batteries, 1.5 Volt, 10-Year Shelf Life, 36 count (Pack of 1) --- ## 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.no/products/537543852-2-pack-battery-tester-universal-battery-checker-for-aa-aaa](https://www.desertcart.no/products/537543852-2-pack-battery-tester-universal-battery-checker-for-aa-aaa) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
