I looked up those batteries you were asking about. Since I don’t have them, I can’t test them. There is a slot on side of kit for some of these batteries. I just never used it but was having a look at it after my last answer. It’s discreet so barely noticeable. At end of the day this is a fantastic piece of kit and it’s only 20 quid and should be in every household. **Q: Why does this item have a subscribe, does it only last a few months?** A: The item seems to be durable. As for now I don't have any problem with it. You can just ignore the subscription and buy just once. I think the subscription is to suck more money out of you 🤣 **Q: On the front of the battery tester top right can any one tell me what the 2 silver buttons are for please.** A: They are for testing 9 volt oblong shaped batteries, the ones with the terminals side by side at the top. ## 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 - Duracell Coppertop AA Batteries with Power Boost Ingredients, 24 Count Pack Double A Battery with Long-lasting Power, Alkaline AA Battery for Household and Office Devices --- ## 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.tw/products/389063323-universal-battery-tester-with-lcd-display-multi-purpose-small-battery](https://www.desertcart.tw/products/389063323-universal-battery-tester-with-lcd-display-multi-purpose-small-battery) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-21*
