Battery dies, dig/uncover/jump, things are OK again

Post by matthew1 »

I was using the cigarette lighter to power a 12-volt tire inflator compressor to inflate a small baby pool thingy for my 10-month-old son. It took about 20 minutes of runtime to inflate the pool, then the inflator was shut off but not unplugged, then -- this is where the story gets murky -- sometime later the key was removed from the car. My wife was in charge of that (why the story is murky).

Next day, no power. So I jumped it from my 850 after digging in the back to get to the buried (original OEM) battery and things are fine. They really enjoyed designing a "tamper-proof" battery location ;-).

You know there are jumping points up front on the newer V70's, Matt? :mrgreen: They're under a little plastic cover by the fuse box.

These cars do NOT like the key being on for more than 15 minutes, PLUS the fact that you were charging an
older battery, it just died.
(Happened to me a long time ago)!!!

You may want to buy a new battery if this is the original,
I just had to put one in an 05 (R) with 40K miles!

What is the proper and safe way to boost the battery?

:idea: Wouldn't want to "fry" any of Vovlo's sensitive computers!!!
They've done studies you know. 60% of the time I work, every time!

That jumper port above. Connect the negative cable to part of the frame; connect the positive cable to that; then connect the other two to the other car's battery.
