I can handle any size battery and gives result in just a few seconds. It is very accurate and very readability. I like how it is made with big screen. The only thing that I wish it had is nice case or pouch to carry it in. ### ⭐⭐⭐⭐⭐ Great Tester *by M***. on May 14, 2026* This is a great tester. This is my second unit. I bought one for my home. I just bought this one for my business. Any battery tester will tell you the voltage, but this one also analyzes the percentage of remaining power. ### ⭐⭐⭐⭐ seems to work well *by A***Y on March 29, 2026* This seems to work, and is probably more accurate than less expensive voltage testers. Only downside is that it is a bit awkward to use; the positive terminal is on the device, and the battery must be held in a slightly awkward position for a few seconds to test. This is a minor issue most of the time. ## Frequently Bought Together - 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 - 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 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/635883642-dlyfull-battery-tester-lcd-display-universal-battery-checker-for-ni](https://www.desertcart.gr/products/635883642-dlyfull-battery-tester-lcd-display-universal-battery-checker-for-ni) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-31*
