I have a Honda rebel 2018 300. My battery died on it, I'm assuming that I left my aftermarket LED glow lights on by accident. I use a trickle charger to charge it up to 25% or so roughly, and then I started it and let it idle for 5 minutes and took it out for a ride. As I was riding between first through third gears, the bike would lung Forward and backwards, as if it was losing power.

I stopped, and now I have it idling and it is fine. I'm afraid to ride it again, not sure if the battery is just not fully charged or if it is losing power or has a loose connection or something.

Help!

A motorcycle needs a fully charged battery to run. It's not like a car where you can jump it and as long as the alternator is good it will run even without a battery. After your battery is back to full you should be ok. On a side note it's always a good idea to add accessories after the ignition side of the power block to avoid this.

My 2018 Rebel 500 has started doing that "power loss lunging thing" too only its intermittent. Scary as **** at high speed or on a curve. I only have 3700 miles and have never run my battery down. The shop is having a hard time figuring it out because they cannot duplicate it at will. I have no mods, either.

Its VERY frustrating

I don't know if water is your problem, but water can get into your bike's gas tank in a number of ways, but the most common is by condensation. If you've allowed your motorcycle to sit for a period of time in cooler weather with a half-full or nearly empty gas tank, you've created conditions for condensation to form inside the tank. Always keep them full of gas when parked for a few days.

Have you sold your bike yet?

Back to the original issue.
The bike CAN NOT charge a battery drained that low.
A trickle charger CAN NOT charge a battery that is drained that low - the reason for the name "trickle" charger. Its slow and low charging.

A battery needs a charger that can fully charge the battery back to FULL voltage level.
After that it MAY be good. Just because the charger states the battery is fully charged, doesn't mean it has the power to start the bike.
And that can be proven by getting the battery load tested.

A battery that is NOT fully charged, can cause running issues and put a strain on the bikes charging system!

If the battery is 3 years old or older and it has problems starting, and /or you just drained it fully and its old - get a new one. You be way better off.
Why get stranded?

I had a 3 year battery. Parked the bike at a local store. Bike gave no indication of problems. Came out of the store - no start - battery dead!
It can happen that fast. Even have had it happen like that in a car! Here the winters are below zero a lot. If my car battery is 6-7 year old I will get a new one for the winter. Don't want to have a no start because my battery is not up to it!! Same with my bike. When I hit the start button - I want it to start!
