Handles all size batteries and gives you good reading as to how strong the battery is ### ⭐⭐⭐⭐ Review *by N***L on 2 March 2020* Works as expected. A tad difficult to pop out AA batteries--could be designed better for that. Love the numerous battery types supported and highly usable and intuitive design. Note that this is a relatively cheap product--it does not put a load across the battery to allow you to determine if the battery can really hold its displayed voltage under a typical load. You are basically getting a quality product relative to the cost. ## Frequently Bought Together - Battery Tester, Dlyfull LCD Display Universal Battery Checker for AA AAA C D 9V CR2032 CR123A CR2 CRV3 2CR5 CRP2 1.5V/3V Button Cell Batteries, 1x AAA Batteries Included - Dlyfull Battery Tester, Small Battery Testers Universal Battery Checker for AAA AA C D 9V 1.5V Button Cell Household Batteries - Dlyfull Battery Tester, LCD Display Universal Battery Checker for Ni-MH, Ni-CD, Li-ion, Alk & LiFe04 Batteries(AA AAA C D 9V 12V 18650 CR123A 2CR5 CR2032 Cells), 2X AAA Batteries Included --- ## 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.co.uk/products/401737182-battery-r-lcd-display-universal-battery-checker-for-aa-aaa](https://www.desertcart.co.uk/products/401737182-battery-r-lcd-display-universal-battery-checker-for-aa-aaa) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
