Very specific size. *by on Reviewed in the United States June 26, 2026* These work well. I have a Radon system in my basement which has a small monitoring device, and these are the batteries it requires. The last quite a while, so the capacity is good. They are not rechargeable. ### ⭐⭐⭐⭐⭐ Probably a good battery, don’t know, can’t use it *by on Reviewed in the United States August 9, 2026* My attempt to find the right battery for a product I bought from Temu and it wasn’t the right size. Decided to keep it in case I can use it somewhere at some time. It’s very unusual size. ### ⭐ Unusable batteries *by on Reviewed in the United States January 10, 2026* These batteries are stored improperly or are terribly aged. Upon insertion into sensors for a security system or other device, the voltage dropped to 1.17Volts vs the required 3.65Volts. Buyer beware. No effort is made to maintain the stock under temperature control. Nor is there any assurance that these items shall deliver a minimum of 3.6Volts. Thus they are incapable of delivering anything close to the operating voltage, never mind the buyer’s expectation of getting 8 years of use. They are unusable as supplied. ## Frequently Bought Together - EEMB 20-Pack ER14250 1/2AA 3.6V Lithium Battery - Non-Rechargeable, Long-Life for Home Automation, Alarms, & More - LampVPath (Pack of 2 14250 Battery Holder, 1/2AA Battery Holder, ER14250 Battery Holder, 1/2AA 3.6V Battery Holder with Leads Wires - LampVPath (Pack of 4 14250 Battery Holder, 1/2AA Battery Holder, ER14250 Battery Holder, 1/2AA 3.6V Battery Holder with PCB Solder Mounting Lead --- ## 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.sk/products/655079182-er14250-20pack-1-2aa-3-6v-lithium-battery-1200mah-non](https://www.desertcart.sk/products/655079182-er14250-20pack-1-2aa-3-6v-lithium-battery-1200mah-non) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-22*
