(Because of 10 year shelf life claim) The original battery lasted close to four years (low power consumption item) and the other collar is still green and good. I needed one today and ALL Four are DOA. And the recommend replacement batteries are 14250 with 3.6 volt . **Q: Where can i get a charger for it** A: These are non-rechargable, it says so in the description. **Q: Can the tabs be removed from the battery.? If so, how?** A: No, you cannot remove the tabs from the battery. If you need the battery without the tabs, please visit our Amazon Store or search EEMB ER14250. We have ER14250 without tabs available. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good, long lasting battery. Very specific size. *by M***. on 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. ### ⭐⭐⭐⭐⭐ Great value and quality rare battery *by L***E on June 5, 2026* Finally found a brand that the batteries were not already dead by the time of delivery.. 100% full .. Thank you ### ⭐ Unusable batteries *by S***M on 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 ER14250 Battery 1/2AA 3.6V Lithium Battery Li-SOCL₂ (4-Pack) Non-Rechargeable XL-050F SB-AA02 LS14250 for Dog Collar Meter Sensor Movement Monitor/Home Security System/Alarm System - LiCB CR2032 3V Lithium Battery(10-Pack) - Amazon Basics 8-Pack 9V Alkaline Batteries, 5-Year Shelf Life - for Smoke/CO Detector, Electronics & Audio --- ## 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.hk/products/55109707-er14250](https://www.desertcart.hk/products/55109707-er14250) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-11*
