Leaking Batteries!

[MonsterMadMarty]

I apologise in advance as I'm sure this question has been asked before!

Why are Monster prone to battery leaks? What step can be taken to avoid it?

Cheers

Purchase a Ballistic, EarthX, Alien Motion, Shorai or any other kind of LiFePo4 battery. You'll never have that problem again, you'll shed a ton of weight off the bike, and the battery will be more reliable.

Older Monsters had conventional lead acid batteries.  They could leak since they contain liquid electrolyte.  But, unless the case cracks, the battery is tipped over and there is no serious overcharging issue as long as the overflow tube is on and all is good you should have no problem.  Model year 2001 on the Monsters there was a switch to AGM (absorbed gas mat) batteries, no loose electrolyte, theoretically no problem.  Plus you could mount the battery horizontally.  So much for theory, in the beginning Ducati as well as Yamaha and probably a few others factory installed a bunch of AGM batteries that managed to puke acid, reason unknown.  Since then all has been well with AGM batteries, which are now available for older bikes.

Yep. Before switching to Lith batteries I used an AGM Odyssey battery. Damn near bulletproof. Buuut it was 14lbs....
