Just received my 2019 C400x that I purchased out of state.It arrived today after a 45 day trip with some major issues to say the least !LOL
Battery is completely dead and Fob is in one of the front compartments that can only be opened when the bike has power.Tried to trickle charge the battery,with zero results.Then I tried to jump start it and to my surprise that didn't work either.Both trickle charge and jump start were attempted with alligator clips connected to the battery.I assume the battery is done for,so I'll replace it.I am worried by the fact that when i tried to jump start,I got no power.No lights,nada!Any ideas?Shouldn't I be able to jump start even if the battery is completely bad?

If the battery dropped a cell or 2 and you have just small alligator clips attached to an external battery I don not believe you can pass enough volts to get things going. Try a fresh battery first.

Amps not volts.
Tiny amounts of metal can conduct millions, yes millions! of volts.
Small clips/cables will heat up if too small.

In my experience, my c 400 gt battery lasts 2-3 weeks then its almost flat. A distinct contrast to my Honda forza which lasted all winter without battery maintainer ! This scooter has some power drain, and it seems common with them.
btw I have also the latest software update at 0022-006-020 , so its not fixed yet

I own the C400GT with no issues with the battery. It’s been sitting in the garage since the first week of October.

I started it last weekend just to make sure it would start....,which it did.

There will always be a current drawn on the C400’s with the keyless start which is always active. The system also ‘listening’ for the alarm off/on command from the remote active.
