What type of battery should I use in my SnapShock Plus?
Your Snapshock Plus will work best with an Ultralife Lithium 9-volt battery. The lithium battery offers 1200 mAH of charge capacity versus the 600 mAH of a typical alkaline battery. A Zinc carbon 9-volt will provide 400 mAH or less. Low-temperatures will exacerbate the problem to the extent that systems will not activate below freezing temperatures.
