Alkaline Batteries in winter?
« on: December 17, 2006, 06:00:56 PM »

 More and more modules used batteries. When used ourdoor are they the best value? In Québec we have almost two months in winter with temperature around -20/-25C.  I know batteries don't like cold temperature. Is there something better with rechargeable batteries?  Thanks!

I don't think re-chargables like cold weather.
Lithium cells are much better in cold than alkaline cells. That said lithium's are much more costly.

I have two motion sensors that used to run on 4 x AA's each.

I removed the batteries and converted both motion sensors to recive power from a 6 volt DC wall wart.
Both of them share the same wall wart power supply on my porch.
I used very small dual wire and hid the wires so it all looks nice.

Just throwing out ideas.

What modules use batteries?  I know the CM15A and CM11A interfaces do, but neither is a module.

The DS10A and MS10A (door/window sensor & motion detector) use batteries in the DS7000 security system.

In Michigan I use the carbon zink without any problems.  They also put out a bit more voltage and give remotes a bit more range.  I typically put a low leakage Tan. capacitor across the battery, that extends the life.
