I've got $49,000 Mi on my sr-14 and I'm on the third charger I have a 20 amp direct feed that I plug the bike into nothing gets warm except for the charger you can fry eggs on that thing I hope zero changes this charger sometime I wonder if a off board charger but also balance
the cells does anybody know .

I'm at 30,000 miles (48,000km) on my '14 S and I just replaced the charger. Wasn't very difficult but will be looking to use dielectric grease on all connectors before riding it again.
Never checked my previous chargers temperature before failure so not sure what higher than usual heat feels like.

Since my onboard charger died I've been using a Quiq charger. Works just fine (and it does get hot).

2014 SR, 11,200 miles.

I'm on my second internal charger. Both replaced under warranty. However, the second one happened this August, at 10,890 miles, past the bike's 2 year warranty. Maybe they consider the charger part of the battery system's longer warranty? Thanks to Zero for covering it!

This is my commuter bike and I only use the internal charger. I used to charge at work, plug in right after stopping and anywhere else I could, but since the second charger I'm doing the following to keep the third charger from failing:

I only charge at night in my garage with a fan blowing across the belly pan and plug area to keep everything cool. I believe charging outdoors or with a recently run bike "cooks" the charger.

I should get the quiq charger as a backup.

My on-board charger just started doing something strange.  Two weeks ago, it would charge to 98%, then a day later, wake up and finish charging to 100%.  Now it is charging to 92%, then the next day it wakes up and charges to 96%, a day later it charges to 99% and the following day, wakes up and finishes charging to 100%.  Very odd.  Of course, I can speed up that charging routine by unplugging the cord and plugging it back in to get it charging again.  I have no idea what this indicates, but I hope it isn't getting ready to fail. The charger doesn't get very hot, just a little warm to the touch and most of the time I rarely allow the battery to run down past 60-70%, so all of my charges (except for once several years ago) are not very long and all have been charged from my 125 volt (measured) garage wall outlet.  Ambient temperatures while charging are typically 60-70 degrees F.  My bike currently has 12K miles on the clock.

Richard, that description is exactly what prompted me to replace the onboard charger. It started being an overnight charge left the SoC in the morning at 98% and over a few weeks, the SoC reduced to 95%, 92% and then finally 90%. If you unplugged and plugged back in, it would often get to 100% or if you left it for a day or so, the second charge would start to bring it to 100% but eventually it was taking 3 plug ins to get to 100% or more than 3-4 days to initiate all the charges to get to 100%. I contacted Zero and even though out of warranty, they were kind enough to replace the charger at no cost. Zero support have been fantastic and even though my motor has been replaced twice and onboard charger once, their communication is always precise and in a reasonable time frame. I think you should contact them before it develops further.

Thanks, TheRebelFred.  I'll see what happens next. But I plan to buy a 2018 Zero as soon as they become available and give my current Zero to my daughter. If it still has a problem then, my son-in-law can take care of replacing the charger.

Richard, I don’t know who’s luckier, you or your daughter but I do know that the riding these things become quite an addiction!
