Any battery can and does fail, from vibration or any of a number of other reasons.

The only difference is when a lithium battery fails it can be spectacular and sometimes dangerous.

The bike and I both survived my lithium battery failure. I will likely stay with an AGM in my bike unless some better technology comes along.

I figure there are plenty of risks to worry about just riding a bike without having to worry about catching on fire because of a battery failure.

Amen.
 
OK so what is the recommended make and model of battery for a MK3?

I've been using Motobatt MBYZ 16HD on my Mk.3 for a couple of years , bike has Podtronics and 4 brush starter motor. Absolutely no problems whatsoever.
 
Hello,
I had the very same experience with my Commando. But I caught mine at a crossing directly at an emerge of the Autobahn. The thing was smoking like hell. I burned my hand trying to disassemble the batterie.
Anyway, the first thing I did after installing a new batterie, I also installed a volt- meter. After starting the bike I was surprised seeing up to 16 and more volts on the meter. So I threw away the cheap rectifier and changed that to a Podtronics. Now my volt- meter shows me 14.5 Volts max. Which even for a Lithium batterie is ok. I think that this is the point.
Best Regards
Klaus

I hope this is true. I too have installed a voltmeter on my bike and will keep an eye out for over voltage. So far I've seen 14.5 V max and as you say, that should be OK.

Maybe I'll start carrying a fire extinguisher in my tail bag too... :confused:

Hobot recommended that, some years back...
I adopted it.

I'm using a MotoBatt MBTX12U on my MK III, standard charging system with zeners, early Boyer & standard (working) ES - the battery has been in place since March 2017 & covered 7.5k miles without issue (so far ;-).

Odyssey PC 625 as recommended on this forum. Had to hacksaw off the fins to get it to fit. Podtronics rectifier , MK 111.
 
Fire extinguisher.

My turn signal cadence = voltage

I think it's correct to say that Lithium Ion batteries are fragile and require minutiose care. Care should be taken to prevent vibration (long term vibration testing has been shown to increase internal resistance and deterioration of cells), elevated heat (cooling may be required), charging Li-ion below freezing, full charge and full discharge shall be avoided, and these batteries have no tolerance to charging at a faulty voltage level which will kill the built-in electronic components.

Please note that a regular fire extinguisher isn't very effective against shorts and excessive heat generation inside a Lithium Ion battery.
Choice of extinguisher to limit fire depends on the battery's composition. Lithium metal batteries require special agents to be effective.

I got my small fire extinguisher to carry, in case of a fuel fire, MAYBE put it out when still small.
I use AGM’s in all my numerous powersports platforms.
I weigh 240, so, if 4 lbs. becomes important enough to me, I’d give up IPA’s.. wait, that’s just silly.:p
I have no intent of playing roulette with my vintage bike for the weight savings of three quarts of gas.

Seems none of these guys had an FE nearby. Didn't work out so well for one poor chap. Doubt it was a LiPo battery though.

 
^^^that is absurd

FE nowhere to be found, stand around watching as it burns. Really no excuse for that.

Can't believe how quickly they got that tank off...must've been some quick removal setup...would take me 5+ minutes with several different spanners to pull mine.

One time in the 80s, was riding behind a VW van loained with band gear that started spewing flames out the engine compartment. I flashed and honked (with the feeble Lucas horn) and they pulled over as did I.

As they unloaded the gear furiously, I went up to the apartment building and pushed all the buzzers until someone let me in. I busted the glass on one of the FE boxes with by gloved hand and borrowed it.

After opening the engine lid on, the first spray sent the yellow powder back against the firewall and left me in my leathers looking like a bumblebee.

Fire truck arrived just a few mins later, all they did was rinse off the powder from the van.
 
I sacrificed, nearly an entire case of beer :(once, to put out a small engine fire on the car parked next to me. My wife was tearing them open, handing them to me, bucket brigade style.
We saved the car.:p
I hope it wasn't some lame cager at least....otherwise a shocking waste of good brew....
 
Back in the early 80s when I converted my Commando to the Featherbed I had a similar fire while I was on it, V stack, no air filter and a slight seepage from one of my fuel tap, leaving my mate's place kicked her over, backed fire through the carbie and the bike was running and my mate was waving his hand to my bike, I thought he was waving good bye till the flames ran up my left leather coved arm and up she went, I got off pretty quick, lucky my tank wasn't bolted down and was able to pull it off as the fuel lines were melting, freaking out by this time as my bike was going up in flames, we ended up putting it out with a canvas trap.
Seat completely melted, new paint job completely burnt and a charcoal mess, wiring all melted and speedo glass cracked and mileage numbers all melted, other than that everything else survived, next day had it rewired and a the fuel taps replaced, kept the charcoal paint job as it was and was ready to go but had to wait for a week to get the tank redone, I rode the bike like that for about 2 years and could win best rat bike at any bike shows.
Moral of the story don't run volicity stack without air filters and a leaking fuel tap, well I never ran VS after that, new K&N filter fitted straight away, but the worst bit a week after fixing it up my Boyar black box pooped itself from the fire 100 miles from home, to this day I still ride without my tank bolted down.
