Is this a good choice for smoke detectors?

It depends on whether your smoke detector is wired into the house wiring and the battery is just a backup, or if the battery is the only power source. If the battery is a backup to household power, a standard heavy duty (Non-alkaline) is best and also much cheaper, but needs to be replaced yearly. If the battery is the only power source, an alkaline battery like this is a good choice. Smoke detectors that are household wired and use the battery as a backup need a higher peak voltage to keep them from the occasional chirp sound that drives my dog crazy. A fresh/new heavy duty (non-alkaline) battery puts out over 10 volts and will easily last a year onder the light load of a smoke detector. A fresh/new alkaline battery will only put out about 9.4 - 9.5 volts, but it will handle a greater load for a longer time. My house wired smoke detectors start chirping at just under 9.4 volts, so my dog hates it if I use alkaline batteries in them.

Anybody know the mah rating of these?

The box nor battery have MaH. There are charts of their website for specs and usage, but no MaH. http://ww2.duracell.com/media/en-US/pdf/gtcl/Product_Data_Sheet/NA_DATASHEETS/PC1604_US_PC.pdf

what is the expiry date

The batteries I purchased in 1/2015 have a 3/2019 expiration date. It all depends on what seller you use.
