I am confused about battery testers for house hold batteries, AA, AAA, 9V, etc.
Recently my smoke alarms started chirping so I changed the 9V batteries and no chirping.
However, the replaced batteries tested good using GBT-500a battery tester.
I was told that batteries need to be tested under load, not sure the above tester did that.
Anyway, you would think there would be a lot of testers that provide a load for testing all types of batteries.
Can't seem to find that product, or I am not understanding what tester I need.
Why would perfectly good 9v batteries cause the alarm to chirp.
Comments, suggestions
Thanks
