Physically, why?

Just curious. I went to start my excursion for the first time in 7 weeks last night and it was game over. I put it on a charger all night and it started fine a few minutes ago.

But I am curious, what actually goes bad in the battery? Hopefully mine will be fine.

Your Excursion is ruined.

Send it to me for proper disposal.

Fully discharging a battery does not "ruin" it. But it does reduce its life expectancy.

Google lead-acid battery chemistry.

OK, you have lead and acid in there.



The acid eats at the lead and it goes into suspension and stays near the plate where it came from. When you charge the battery the lead is attracted to the plate and gets stuck back on. Now when you go to use somepower the lead is stripped off again and so forth.



Now, when a battery sits too long the lead moves too far from the plate and can not get back to it and your battery goes bad.

There's some electro chemical hoo haa going on in there that fucks your shit up when they get totally discharged. A lot of times in the winter the specific gravity stuff gets all out of whack and it freezes up. And that's the end of that battery.

Do plants crave batteries?

Silly northerner, you know they don't have winters out there in New Mehico...


I do like your explanation though.

Silly Gulf Coaster. Never heard of elevation and the temperatures that go along with said elevation in the winter.

OP- Like mentioned above, it's a chemical thing.

In a lead acid battery, sulfation occurs on the lead plates after the battery voltage drops below a certain voltage. This raises the battery's internal resistance, which makes current flow harder and starting suffers. If left long enough the plates will grow enough sulfur scale to short out between cells in the battery. At that point the battery is junk.

You can fix a sulfated battery with a desulfator and basically make it like New again, but one that is shorted inside can't be recovered.

For lithium cells, the chemistry goes inert below 1.8v and can't be recovered.

You mean it's not dead battery elves?

The sulfuric acid is able to corrode the metal innards and shit don't work no mo.
