Enegitech9V Lithium Battery, 9 Volt Battery 1200mAh Non-Rechargeable for Smoke Detector, Fire Alarm, Carbon Monoxide Detector, Metal Detector (9V 8 Pack)

Consistent output in smoke detectors for 5 years before needing replacement. No leaks. Worth the money spent for the amount.

We replaced all the batteries in our smoke detectors (electrical) with lithium batteries. We expect they’ll last 8-10 years. Otherwise we had to replace them yearly & what a pain! It’s well worth it to use lithium batteries. We have 12’ ceilings & it’s hard to put in new batteries. These are a good solution to replacing yearly.

The batteries arrived as promised - They are in my smoke detectors & seem to be working fine. I am not able to talk about the quality because they are supposed for last for 10 years and I only have them a short time. Due to the number of batteries I purchased I was able to share some with friends. The large volume size was a great deal.

So far so good, replaced the batteries in my brand new KiddeFireX Hardwired 120-Volt Inter-Connectable Photoelectric Combination Smoke and CO Alarm with Voice detectors. They are a DIRECT replacement to a standard alkaline 9 volt. Regarding the smoke detectors I used them in, they sell them in 2 models, 1 with standard alkaline and 1 with the 10 year Lithium. I found it less expensive by approx $30 to get the standard battery model and replace with these. Now not to be sarcastic but I will not know how well these perform till years down the road but as I said before so far so good. I test several times a year to make sure the 10 detectors in series are functioning and If I'm around in a few years, I'll update this review and let you all know how they are holding up :>))

I bought these for my smoke Alarms. Unfortunately I didn’t get around to putting them in until three months later, and one of the batteries is leaking. It makes me worry about the stability of these batteries that are supposed to be lasting 10 years.

I installed these batteries on 16 smoke detectors in 10/2017 and had few of the went bad immediately. Now in 02/2022, Half of the batteries are bad prematurely from the 10 year claim per the seller/manufacture. I do not recommend these batteries as they do not stand last.

I needed to purchase several hundred batteries for some water sensors for a condominium complex. Enegitech went out of their way to facilitate a volume order on their website, gave me a great price, and free shipping. When it comes time to replace these batteries, I’ll buy from Enegitech again.

I got tired of changing the batteries in my smoke detectors every year with regular batteries. I bought these because they are designed to last ten years. I've had these in just one month, and so far so good. Since smoke detectors only last about 10 years, I won't worry about until then.
