Generally standard 9v batteries would die after a power outage, ive replaced them all with lithium no problems in since. **Q: are these l522bp-2 the same as advance lithium l522 ?** A: Nope, different. "9V Ultimate lithium" are Energizer's current product. Energizer '9V Advanced lithium' has been discontinued so I'd bet that those are old stock. Be sure to check the expiration date. BP-2 just indicates there are two batteries in each individual package. No designation, A plain BP, or Bp-1 would indicate a single battery per package. BP4 would be a 4 pack, etc. **Q: Life span in smoke alarms?** A: Lasted only 1 year 5 months in my smoke detector. **Q: Is there any chance of these batteries used in a smoke detector exploding and causing a fire?** A: Virtually none. This type of battery constuction is by far the most stable of all common types. These are much safer and more stable than NiMH such as rechargeables or "standard" batteries which are generally Alkaline. I use these in any sensitive devices or devices not used often but important. As such I use these in my own smoke detectors and have never had any issue. For what it is worth I've been a FireFighter for 25+ years, so yes they are safe. The one thing to be aware of is that if your smoke detector is hard wired and requires a rechargeable battery as a backup power source then do not use these. These are not rechargeable batteries. ## Customer Reviews ### ⭐⭐⭐⭐⭐ THE BEST WIRELESS TRANSMITTER BATTERIES MONEY CAN BUY *by S***A on January 18, 2026* ALWAYS PERFECT EVERY TIME!

Great quality, slightly expensive but well worth it. ### ⭐⭐⭐⭐⭐ Have Smoke Detectors? Use these so you don't have to replace batts often! *by S***G on April 7, 2026* I have so many smoke detectors in my house that I really don't want to change the batteries so often. So I decided to pick these up as they're supposed to last as long as the detectors do (~10 years). They seem to work very well and I had no complaints. Yes, they're a bit expensive, but they're very easy to put in the smoke detectors and overall I have no complaints. 10/10 would buy again. ## Frequently Bought Together - Energizer Ultimate Lithium 9V Batteries (2 Pack), Lithium 9 Volt Batteries - Energizer Ultimate Lithium AA Batteries Pack, 1.5V AA Batteries, 24 Count - Energizer AA Batteries, Ultimate Lithium Double A Battery, 8 Count --- ## 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.dk/products/27498933-energizer-ultimate-lithium-9v-batteries-2-pack-lithium-9-volt](https://www.desertcart.dk/products/27498933-energizer-ultimate-lithium-9v-batteries-2-pack-lithium-9-volt) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-23*
