Had this 9V to date in my ABUS smoke detector. As I have written me the date of loading on the block, I can see that this battery has been inserted since 09/09/2013. That's not long for a Long Life battery in my opinion. But at the price no wonder (about 3.50) so viell. Previously a golden Ultralife lithium battery was inserted 9V 1200mAh. The has kept 3 years.
I'm going this Varta Longlife Extra Battery E-Block (9V) 1-he no longer buy pack for smoke detectors.
