Non-rechargeable Battery Reference model: ER14250 1/2 AA Rated capacity: 1200mAh Diameter:14.5mm Height:25.2mm Battery weight: 11g Standard voltage: 3.6V, one-time non-rechargeable lithium battery Large continuous discharge current: 20mA Large pulse discharge current: 50mA Operating temperature: -55 ° C ~ +85 ° C Self-discharge rate of less than 1% per year Wide range of temperatures: -55°C to +85°C Superior shelf life Single Use What if your battery doesn't work when connected to the device? 1. Test the OCV(Open Circuit Voltage). You can use the multi-meter to test the voltage. Standard voltage should be no less than 3.6V. If your battery is lower than 3.6V, please tell us. 2. Test loading voltage. The loading voltage should be around 3.2V. If your loading voltage is higher than 3.2V, the battery is in good condition. Due to the passivation characteristic of lithium thionyl chloride, your loading voltage may not reach 3.2V immediately. You can connect the battery with a resistor and activate it with a multimeter. When the loading voltage of the battery reaches 3.2V, then the activation is successful and the battery can be used. 3. If the battery fails to activate or is still unusable after activation, please tell us for help. 1. Thoroughly read the product datasheet before use, inaccurate handling may cause leakage, heat, smoke, explosion, or fire, causing device trouble or injury. 2. DO NOT recharge, short-circuit, puncture, disassemble, deform, heat, incinerate, or place the battery near a direct flame. This battery contains flammable materials such as lithium and organic solvent and performing any of the above actions could cause it to ignite explode or become damaged. 3. DO NOT over-discharge, do not force discharge. In case the battery is over-discharged battery has potential of explosion.

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.

I've ended up buying alternatives.' Update 'Outstanding customer service. I received a response to my review and replacement batteries, which work perfectly. I can't give five stars despite the great service, but I am impressed and will now buy again' ## 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.tn/products/171317532-er14250](https://www.desertcart.tn/products/171317532-er14250) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-14*
