Question

is lithium thionyl chloride batteries rechargeable or disposable

Answer 1

Here is a quite a discussion of various forms of lithium batteries but I can't tell from limited reading whether they are rechargeable or not. I think some are and some are not but it isn't obvious from a quick reading. If you read it carefully you may be able to find a definite answer.
