Runtime is *way* better than the stock battery.Dislikes: none. This battery is somewhat thicker than the standard-capacity one, which takes a bit of getting used to, but that's not really an issue after using it a few times.For $50-ish, this was a cheap way to keep a perfectly functional wireless SIP handset running, and with a significantly longer runtime than it had when it left the factory. Time will tell as to cell life, but it is recommended. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars so good. *by B***N on Reviewed in the United States on June 29, 2018* I have used this for a week now, and I have been able to get 2-3 days per charge, and I do turn it off when I leave work each day, but only charge back when I get a low battery indication on the phone. I don't talk a lot on the phone, but I have it available when someone calls. This battery is double the capacity of the originals in the phone. My originals failed in just a few months of use, so I am hoping this unit is more durable. So far, so good. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works great! *by A***T on Reviewed in the United States on March 27, 2019* Ordered regular and extended batteries. Both work great and hold a charge well! --- ## 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.hr/products/20021491-replacement-battery-for-polycom-spectralink-8400-8440-8450-and-8452](https://www.desertcart.hr/products/20021491-replacement-battery-for-polycom-spectralink-8400-8440-8450-and-8452) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-20*
