I bought two packs (8) total last November 2024 and they are all dead ☠️ dead ☠️ in September 2025. ### ⭐⭐⭐⭐⭐ Last a long time and a great price *by R***. on December 29, 2025* I use these batteries for my garage door tender. Let’s me know when my garage door is open. The batteries last a long time. Last time I changed these batteries was 2 years ago. ### ⭐ 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 100PACK ER14250 1/2AA 3.6V Lithium Battery 1200mAh Li-SOCL₂ Non-Rechargeable Batteries XL-050F SB-AA02 LS14250 TL-5902 TL-2150 for Dog Collar/Meter/Sensor/Home Security System/Alarm System - 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.us/products/663552019-100pack-er14250-1-2aa-3-6v-lithium-battery-1200mah-li](https://www.desertcart.us/products/663552019-100pack-er14250-1-2aa-3-6v-lithium-battery-1200mah-li) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-10*
