3 warnings so you don't get stranded with your motorcycle with a dead battery

How your motorcycle's battery warns you before leaving you stranded

Few things are more annoying than getting on your motorcycle and  finding out it won't start because the battery has given up.

But the fact is that it's rare for it not to give you warning signs before failing. They don't usually break down suddenly.

Another thing is that at first  it seems easier to play dumb and ignore the symptoms. If you do, don't doubt it, you'll end up pushing.

A quick solution could be to call your motorcycle insurance's roadside assistance to solve this problem. You should check if, in fact, you have that coverage away from your home. If not, as mentioned, you'll be pushing. 

1. It's hard to start

It's the first symptom and the easiest to recognize.

If the engine turns more slowly when you press the button or it takes more tries to start, be suspicious.

The battery may be low on charge, or simply at the end of its service life.

If you leave it like that for a few days, it could become completely discharged.

2. Flickering or electrical failures

Another clear warning is when strange things start to fail.

The  dashboard light turns off and on  when you turn the key, the horn sounds weak, or  the turn signals blink slowly.

These are signs that there isn't enough voltage.

3. It's more than three years old (and stays outside)

It's not a mathematical rule, but it is a real fact.

Modern batteries last between 3 and 5 years. But if the motorcycle stays outdoors,  in winter or with humidity, the lifespan is shortened.

If, on top of that, you take short trips or don't use it much, it never gets fully charged.

That's when one day it leaves you stranded. Just like that.

What can you do?

Checking the voltage from time to time helps. With a multimeter, if you have one, or at the shop during any inspection.

It's also a good idea to install a trickle charger if the motorcycle sits unused for long periods.

If you see that the battery starts to fail, don't hesitate:  replace it before it's too late.

You'll save yourself a tow truck... and a lot of frustration.
