9V Lithium Battery, Batteriol 4 Pack 1200mAh Li-ion Batteries for Smoke Detector Wire Tracker Microphone Multimeter Infrared Thermometer Non-Rechargeable

Nice high capacity batteries at 1200mAh. However the plastic wrapping had been wrapped so tight it had distorted the -ve terminals on 3 of te 4 batteries (either that or they were wrapped as damaged - maybe my interpretation is being generous). Still got a connection for the smoke alarm I was using the first one in so no need to return, but could be annoying for other uses...

I purchased these lithium batteries for my Response Alarm system as previous PP3 batteries proved unreliable. I am very pleased with the purchase as these batteries are very competitively priced against ordinary alkaline batteries.

I bought these to replace my old NiMH batteries, which when new lasted about a week, and now last a couple of days. The new lithium batteries have lasted 4 weeks so far, and they're still going strong.

Works well in my smoke alarms

Have installed 2 of these so far and they provide the proper voltage, can not comment on how long they will last for another year
