How to Test Saft 14250s (LiSoCl2) Batteries?
« on: August 29, 2021, 09:24:26 pm »
I use about 25 SAFT LSG 14250s in my security system. Would like to be able to test these batteries somehow. Would prefer a piece of test equipment but can build tester if necessary…and I have plans etc.

Any ideas?
Thanks

Test it how, for what? Remaining capacity? State of health? Remaining shelf life?

Thanks for your reply,

Remaining Capacity
State of Health
Remaining Capacity: Load it with 8.5mA (for practical reasons this is usually just resistor) and measure voltage a few seconds later.

State of Health: This can be accomplished a few ways. I typically just measure the short circuit current of the cell, given the ~5 Ohm ESR of the cell, this could be in the order of 500mA-1A . Open circuit voltage also helps determining it. Then calculate the ESR and that will give you a good indication on this.

Subscribe to what? No load voltage is an accurate indicator???

Thanks, to perform either of these I would like to have some sort of jig to insert the battery in (like a battery tester bracket) that would allow me to connect multiple leads to each end of battery. Any ideas?
