catastrophic battery ?

[Chris Norloff]

Thanks, Dan. That's really amazing. Sure glad you were clear when it blew. I think batteries have a similarity to gasoline, in that they're really quite dangerous, but they're so commonplace that we don't always think how dangerous they can be.

Hey Chris, I've heard of it of because I did it on a 1972 Honda CB350 that had sat under a tarp during a long Ohio winter. I was a youngster at the time, but at least (fortunately) had enough sense even then to hook the cables up to my car last. Blew the top off the MC battery and no I didn't reverse polarity on the cables. Sorry, but I have no good documented evidence of the episode as they were no digital cameras, or internet forums for that matter, at the time. So at least you've heard of it now, but of course it is undocumented.

I've never heard of a large battery blowing up a small battery. I've heard of not running the car when you're jumping the bike from the car, as the car's electrical system can provide more current than the motorcycle system can handle. I've heard of connecting the negative terminals last to avoid sparks due to hydrogen gas around the top of a lead-acid battery. Does anybody have first-hand experience, or have a good documented source of a big battery blowing up a small battery? thanks Chris -----Original Message----- From: DSN_KLR650@yahoogroups.com [mailto:DSN_KLR650@yahoogroups.com] On Behalf Of Dan Bittner Sent: Tuesday, April 15, 2008 7:50 PM To: DSN_KLR650@yahoogroups.com Subject: Re: [DSN_KLR650] Battery problems Hello Richard, If your battery is actually measuring 11.2 amps with no load it's pretty much done for. It probably has at least one dead cell and is potentially shorted out internally, which is what your charging voltage is indicating also. With the short or dead cells the charging voltage is slowly bled to ground and could be the reason why your measured charging voltage is so low, your may be just fine with yet ANOTHER new battery ( yes batteries are a pain ). If this is the case, DO NOT jump it with your car battery ! Your car battery will be more than willing to pump 60 or more amps into your bad motorcycle battery with potentially catastrophic results. I usually don't critique someone else's advice but I'd hate to see anyone blinded by flying battery acid. It can and does happen so if you do it at least wear some good eye protection. Good luck with it, Dan Bittner Sacramento, Ca.
