Air battery voltage?

Have had my sky and storm for 10 days and allready noticed a battery drop of .3 volts? Does sound right? So 30 days at that rate would be .9 volt or almost a volt gone. And these are the orginal batteries?

Some have said on here have gotten 8 months on orginal batteries? At the voltage drop I see wont even get near that? Mind you it has been cold here lately and cold weather can have an effect on batteries.

I do notice though through the day the battery voltage can change slightly and go up and dont .1 volt

Yes, that is normal.

That’s good to know. Thanks

Also note that the voltage drop is not linear. The initial drop is typically faster then levels out for a long while then drops quickly at the end. This is assuming you are using the recommended Lithium batteries.
