They've gone through 5 hot summers in a non-AC veranda which turns into a greenhouse, and 5 quite cold winters where it definitely must have gone below 0°C.
I guess I can dispose them. Am I correct in assuming that they should not explode/fire up if broken or short-circuited, when without charge?


When totally discharged (ie, to near zero) they should be fine (should be able to go to standard battery disposal). Got any meaty resistors around? smile
