dimensions and schetch of 9 volt lithium non-rechargeable battery

It only takes 3 thionyl chloride cells to make a 9 volt battery, so we can stuff a lot more capacity into the 9V case.

Advantages:

From 2.5 to 10 times the capacity of alkaline and carbon zinc batteries
Much better voltage hold-up during discharge makes it ideal for instruments, smoke detectors and guitar pedals
Extremely long shelf life--up to 20 years
Better low temperature performance than alkaline, carbon zinc or leclanche batteries
Double sealed hermetic casing shell, cannot leak

Comparison of the 9 volt lithium battery with alkaline and carbon zinc batteries

Disadvantages

Peak currents are not as high as alkaline C cells, but are great for most purposes digital voltmeters, guitar pedals, garage door openers and TV clickers (see the discharge curves below).
Cannot be charged under any circumstances.
