Q:For a smoke alarm I need a square head not octagonal help
by|Dec 31, 2022
1 Answer
Answer This Question

A:  Hello. Most 9 volt batteries today have an octagonal head on the plug instead of the old square one. We don't sell a 9-volt with a square head.

              Q:How many years will it last

              Answer This Question

              A:  It is meant to last 2 years. I have used them, and they lasted that long.

              by|May 12, 2022

                A:  Hello. The answer would b no. The battery will need to be replaced every 6 months to a year with a new 9 volt battery. It will need to be a battery of a make and model listed in the owner's manual. We would strongly recommend a battery with a use-by date of 2 years out if you use a carbon zinc battery or strongly recommend a battery with a good use-by date of 3 or 4 years out if you use an alkaline battery. Batteries close to their use-by date can often not be powerful enough for our alarms or not last 6 months to a year. For best results, use an alkaline battery as listed in the owner's manual and with a really good use-by date of 7 to 10 years out.

                  Batteries do not last
                  I have had a few Kidde alarms and all have had the same issue, the batteries do not last more then 3 or 4 months and that is with the unit plugged in to the wall. I now have a new one that I purchased just 3 months ago, it has been plugged into an outlet and tonight it is beeping with the LB message, I purchased two of these and the other has not beeped yet. I tried replacing the battery and the terminals do not fit. I have had it with these units. Why do the batteries die so fast when they are plugged in?

                    LASTED TWO MONTHS! NOT TWO YEARS!
                    Bought to replace the batteries that came with two Kidde smoke alarms bought 08/20/2020, The original batteries gave 23 months of service. So, of course, I replaced them with more Kidde batteries. THE NEW ONES ONLY LASTED TWO MONTHS! NOT TWO YEARS!
