Cc ### ⭐⭐⭐⭐⭐ Good quality batteries *by S***S on 15 July 2025* Batteries work well. Fast delivery ### ⭐⭐⭐⭐ The work... *by A***N on 13 August 2023* I have these inside a bluetooth temperature monitor inside 2 freezers and a fridge. At circa -21C the voltage dropped quickly over a couple of weeks so the units report about 75% battery remaining. I was initially sceptical of the claimed low temterature performance as a result but the voltage has now stabilised and all seems well. In addition I noticed that one of he freezers ran a defrost cycle recently, bringing the temperature up to about -10C for a short period. The voltage recovered considderably when this happened so I am reasonably sure that the capacity is good and the low, well reduced, terminal voltage is a function of temperature. Even if the battery life is 50% of the anticipated 12 months of service in these devices, becaue of the extreame loction, I still think the performance is more than adiquate and the price is reasonable. A 'typical' coin cell would not function at all at these temperatures so hat is to complain about. ## Frequently Bought Together - EEMB 5 Pack CR2477 Battery 3V Lithium Battery Button Coin Cell Batteries 2477 Batteries DL2477, ECR2477 for Electronic Candle, Light, Remote Control, Key Fob, Alarm, Contact Sensor, Smart Devices… - Amazon Basics CR2032 Lithium Batteries, 4-Pack, Child-Proof Package, Non-Coated - AirTag Compatible - PGSONIC CR2450 3V Lithium Battery (5pcs) --- ## 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.ni/products/417518115-cr2477](https://www.desertcart.ni/products/417518115-cr2477) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-07-07*
