SD MKII question

[ancient puffer]

I looked as far back as I could, but it seems most of the threads are deleted

Anyway, I'm old, so my memory isn't worth squat, but I seem to recall something about the switch in the end of my SD blowing out in the event of a rapid discharge/protection failure. Can anyone verify that this is true or not?

I love my SD, and with all the battery hoopla of late, it occurred to me to check in case anyone asks me. I searched the website, but couldn't find anything about it.

Anyone know for sure (or, if not the switch blowing out, is there a "vent mechanism" built in)?

Thanks

The battery used in the SD MKII is fused to prevent overheating and venting in the event of a rapid discharge failure.
To the best of my knowledge the switch does not blow out in case of battery venting.

I knew the battery was "protected" for overcharge, its good to know it's good for overheating as well. Now I'm wondering if I need to drill a vent hole "just in case" ("protection" devices sometimes fail too). Hmmm, I may be at the point of diminishing returns here. *sigh* decisions, decisions....

Thanks for the reply

I guess one could drill vent hole(s) discretly in the area of the switch at the bottom of the unit.

Yeah, I *could*. I just can't bring myself to do it, though. Has anyone even heard of this happening with an SD? I have had an overdischarge situation (user error) on my SD, but, as expected, the battery shut down. The atty got pretty hot, but other than the battery, no harm was done.

Its such a quality PV, I hate to go mucking around with it. My impression is that venting is within the realm of "possibility", but at this point, it seems pretty unlikely. Any thoughts on this?

The SD has been around for quiet a while, which says a lot about its durability and reliability. If there were *issues* they would be easy to find on the boards.

Thanks, VaporPhoxxe, that's sort of what I'm thinking too. I've scrounged here, TW's forum and Trog's forum and haven't seen a single incident of it happening. Although I *have* seen a few cases of SD's getting run over by trucks, buried in pavement, even tossed out the window. But I still take mine out of the house, I guess you can't allow for every little thing that COULD happen.

I'm really just busying myself to try to keep from ordering another one for backup

You got me thinking there (briefly) and thought about drilling mine, then reality set in and I said to myself, there is beauty in simplicity. It's like doing touch ups on the Mona Lisa.
