Re: House Battery - Should they last more than a year?
David mentioned pulling the fuse for the propane and CO detectors. That was mentioned 10-11 years ago (before solar) but I thought that pulling the fuse was a "non-elegant" solution so I long ago installed a DPDT switch which lets me turn these detectors off without the need to get under the sofa to pull the fuse.
Our battery lives have been:
Original -Lifeline 2 years, 4 months
Second - Lifeline 3 years, 5 months
Third - Lifeline 3 years, 6 months
Current battery is a Deka installed 1 year, 3 months ago.
We have solar and so I don't typically bother much anymore with turning off the detectors. The solar keeps the house battery topped off and I rarely (once a year?) drop the house battery to less than 12.2v. Last time I was at SMB West, Peter told me that it is a good idea to plug into shore power overnight every couple of weeks.
