## Description

desertcart.com: Enegitech 9V Lithium Battery, 9 Volt Lithium Battery 1200mAh for Smoke Detector, Fire Alarm, Keyless Entry Door Lock, Multimeter, Metal Detector Non-Rechargeable 4 Pack : Health & Household

Review: Great batteries! - These batteries are great! We use them for the bass guitar at church. They last longer than any other brand we've tried, and we've tried a lot of them. I've subscribed so that we will never run out!
Review: High initial voltage - These are standard Li-ion batteries useful for smoke alarm back-up battery replacement. What I like: 1. Initial high voltage level as received. My Fluke multi-meter measured the battery voltage in the range of 9.70-9.74 volts across all of the batteries. This is important because smoke alram manufacturers I have noticed are upping the minimum threshold voltage at which they trigger the infamous "chirp" in the middle of a cold night (when the resting voltage drops to its lowest). My newest Kiddie alarms start chirping at a full 9.2~9.21 volts - when the batteries are still considered charged and are useful. 2. Standard size, including length. Some replacement batteries are a bit longer and may not fit your device's battery compartment. I have no negative comments, though only when the middle of fall 2025 approaches will I know if these batteries have lasted.

## Questions & Answers

**Q: Does the 4 pack 9V come with battery cases?**
A: no

**Q: Has anyone had a problem with them being a bit larger than a standard alkaline 9-volt battery? I read some brands are tight in smoke detectors**
A: They are slightly larger than normal 9v batteries. If you have the battery terminals that snap onto the battery, you might be ok. I have the type of smoke alarm that you slide the battery into and it’s supposed to “mate itself”. Because of the size difference and the battery being really squishy (not rigid) they did not work for me- I had to return all 8.

**Q: Are they 1200mah or 600mah?  The page says both!**
A: Definitely 1200mah.

**Q: Are these batteries made in China or where?**
A: While my personal belief is that it is safe to assume they are made in China, there is nothing on the batteries or on the packaging that indicates the country of origin.
