Re: Low battery warning on smart gas meter fitted in the outside box
The batteries are replaced usually by the original fitters, or your current energy company can arrange it. It is not a customer usable feature to change the battery which is a special long life unit (10 years?). If the battery finally gives up your meter may stop the supply, but some people have reported it fail in the 'open' position and so give unmeasured gas from then on. The energy companies usually react quite quickly for batteries because it is not a big job.
It looks as though I was going to far into the menu's, so as such I got an Icon display, so as such it was showing me what could be displayed not the current status. So my mistake and panic over, if the battery lasts 10 years with me pressing the button every now and then, that would be fine as I expect we would be into smart meter 2/3/4 by then and the meters be a standard through out industry.
I did try the on-line chat help but could not get past the indoor smart unit, or, they could not help as I had technically left for another supplier!
So thanks for your response and information about battery life.
