Exploding battery

[Firefight]

Shit! - Stuffed if I know really - perhaps the gas that battery’s give off ignited?

Most likely .

The mighty Yama is back on the road.

Problem sorted: internal short in the battery

Thanks for all the help

Battery exploding happened to me too.
25 years ago maybe more, had a Suzuki 250 hustler (great bike) and was riding at around 130kmh on the southern motorway Auckland when there was a huge bang under my seat. Couldn't see anything wrong and the bike was still going, so rode home about 10kms away and found the Chrome disappearing off both exhaust pipes.

End off the battery had blown off and acid was eating away at everything. Washed and cleaned it all best I could and bought a new battery. never found out what it was but it didn't happen again thank goodness.

I just had the same prob (almost) with my VF750F. Stopped for coffee and investigated a high-pitched whistle. Air screaming out of the battery outlet. The battery had blown up like a balloon. Disconnected and insulated the thick cable from the motor, pushed-started the bike and scuttled home.

Now trying to fault-find with a fully charged battery but the Oil LED is only a glimmer. Tested a few leads and I only have 2.4V DC after the ignition switch. Think it's the regulator/rectifier overcharging the battery.

Seems to be common according to the VFR forum pages and the Fireblades at fireblade.org.

Anyhoo, anyone got a wiring diagram for the VF750? Gotta start somewhere, cycling till I fix it. (Or find someone else who can) I can ride the bike OK, but can fix PC's not bikes.

See ya

If the battery vent is blocked, it could lead to a build up of gases which could lead to a bang in situation such as yours.

I had that happen to me in the company sierra many years ago. it was one of those maintenance free batteries but i think the vent got blocked. when i started the car up, it exploded.
