Any experience with LiSO2 Batteries?

Our company is changing out the batteries in all of our AEDs so I have the chance to pick up 6 of these guys that are about 4 years old:

12v 7.5 ah each. They weigh next to nothing, just over a pound each with the casing. AFAIK none of them have ever been used on a patient but they are probably down to under 50% capacity just due to shelf-life. Any of you guys ever used these? Have any information on how they behave? I assume they are closer to Lipo than LiFePO4 in character.

Are they primary batteries? Must be.

Edit: Yep, just confirmed they are primary. Dang it!

Hi, i got some of the LI/SO2 battery, the brand is PowerheartG5. olmost all of them has 12v. I opned oe and checked to see what it has inside. I found 4 cells. On the battery case there is nothing if they can be recharged or not. Anyone could tell me if they can be recharged or not? if yes, how to recharg them. thank you so nmutch. NJM

IMO, these are non rechargeable lithium primary cells.

Very high energy density, and extreme resistance to extreme temperatures, but not rechargeable.

I used to use Tadiran LiSOCl2 (lithium thionyl chloride) primary batteries in some airborne electronics packages. These were the only batteries I could find in the late 1980s that worked down to -40C.

Arent Lithium thionyl chloride batteries non-rechargables ?

Yes, "primary" cells as bmack said above
