Battery backup does it have warning show up that the batteries need replaced? What is backup for? What time period you need to replace batteries as I do not want acid leak from them that forgot to change them and have to buy other access.
George is correct. It will provide you with an alert when the batteries need to be changed. The batteries are for backup should you have a power outage. The Access will hold up to 12 hours of data. When the internet is restored the information will send to My AcuRite and fill the missed information.
I just noticed the AcuRite® AccessTM 09155M on the AcuRite website. Does that replace the current 09150M
smartHUB? If so, is it any better than the 09150M ?? Also, will there be an free
replacement or upgrade discount for my current 09150M?
