Review: Great Batteries - Energizer are definitely the best lithium batteries. They are longer lasting and tend not to break open and leak ruining my equipment. I selected the Ultimate Lithium 9V batteries for my smoke alarms. These should last 2 to 3 years and maybe longer. Tired of changing smoke alarm batteries at 3 AM which is when they seem to fail. No I change them before they fail. Review: Expensive but great 9v lithium battery - I needed new 9v batteries for my safe and saw that energizer 9v lithium are the best and so far my safe opens on the 1st or 2nd code input. Great quality, slightly expensive but well worth it. ## Features - 2 pack of Energizer Ultimate Lithium 9V Batteries - Lasts up to 20 percent longer in toys versus Energizer MAX batteries - Performance in extreme temperatures from -40 F to 140 F ensures reliable use in all seasons - Long lasting batteries have leak-resistant construction - Lightweight 9 volt batteries last up to 10 years in storage ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01684J7P0 | | Antenna Location | Camera | | Battery Capacity | 750 | | Battery Cell Composition | Lithium Metal | | Battery Cell Type | Lithium Metal | | Battery Weight | 100 Grams | | Best Sellers Rank | #24,078 in Health & Household ( See Top 100 in Health & Household ) #23 in 9V Batteries #1,843 in Sales & Deals | | Brand | Energizer | | Built-In Media | Battery Pack | | Compatible Phone Models | L522BP2 | | Customer Reviews | 4.7 out of 5 stars 5,817 Reviews | | Global Trade Identification Number | 00039800911575 | | Item Dimensions | 0.7 x 3.7 x 4.5 inches | | Item Type Name | 9v-batteries | | Item Weight | 0.06 Kilograms | | Manufacturer | Energizer Batteries | | Model Name | ENR L522BP2.H4 LITH 9V-2 EMOD | | Model Number | 30039800911576 | | Number of Batteries | 2 Lithium Metal batteries required.

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 ### ⭐⭐⭐⭐⭐ Great Batteries *by R***E on April 17, 2026* Energizer are definitely the best lithium batteries. They are longer lasting and tend not to break open and leak ruining my equipment. I selected the Ultimate Lithium 9V batteries for my smoke alarms. These should last 2 to 3 years and maybe longer. Tired of changing smoke alarm batteries at 3 AM which is when they seem to fail. No I change them before they fail. ### ⭐⭐⭐⭐⭐ Expensive but great 9v lithium battery *by R***. on March 23, 2026* I needed new 9v batteries for my safe and saw that energizer 9v lithium are the best and so far my safe opens on the 1st or 2nd code input. Great quality, slightly expensive but well worth it. ### ⭐⭐⭐⭐⭐ Fantastic for solid voltage, please understand what "10 year SHELF LIFE" means. *by A***T on August 15, 2020* So I see several reviews complaining about these not lasting 10 years, these have a 10 year SHELF LIFE not a 10 year USE LIFE- those are 2 entirely different things. 10 year shelf life refers to how long these will be viable for sitting on a shelf/stored not plugged into anything. As far as actually putting these into something you can expect use-life to be about the same as a typical 9V or a little longer. I bought these to power the Fishman Fluence active pickups in my guitar because these types of batteries provide very consistent power - which is where these excel compared to your average alkaline 9V which can waver a little in power getting worse over time. The only issue with these is they will suddenly die out on you once they are done but they will give you the same consistent power until its last breathe. Who these are for: -People who have devices/uses that require very consistent power. -People using devices that are subjected to more extreme temperatures. -Expensive devices that could be destroyed by a small battery leak. -People who like to store up on back-up batteries for a long time for later use. Who these are NOT for: -People who think 10 year shelf-life is the same as 10 year use-life. -People looking for rechargeable batteries (these are NOT the same as rechargable lithium batteries) *NOTE: These are very close to the size of your average alkaline battery but ever so slightly bigger since the edges are not rounded so if you want to put these into something where the battery space is a very tight fit it might not fit. ## 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.sk/products/27498933-ultimate-lithium-9v-batteries-2-pack-lithium-9-volt-batteries](https://www.desertcart.sk/products/27498933-ultimate-lithium-9v-batteries-2-pack-lithium-9-volt-batteries) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-12*
