If you disconnect without turning off the charger, the sparks caused may ignite the hydrogen discharged from the battery while charging.
Sometimes even though the voltage at charging is good the battery or alternator could be low on charge or charging low for your vehicles specs.
Be careful if you're charging the lithium battery with a generator connected through an isolator.
Check that battery is connected.
Connected to the negative post of preferably anyplace on the engine.
No, you do not have to disconnect the battery. Just do not start the engine with the charger connected unless the charger is built for starting purposes.
If you question the condition of your vehicles battery, drive to your local auto parts store and they can test the battery and the charging system of the vehicle for you at no cost.
An electrical device can still be on and charging if the fan is off. If the device is plugged in to the wall, or connected to a battery, chances are it is charging.
You can't, unless you disable the actual USB port it is connected to.
Batteries vent Hydrogen gas. You should always connect the positive battery cable first to avoid a spark at the battery that could cause the Hydrogen to explode. The negative cable should never be connected to the battery negative post. It should be connected to another ground area on the engine.
Kia vehicles tend to turn these lightson together when there is a charging issue such as the alternator, battery or cable connections.
charging system not charging battery with new batttery, alternator and fuel pump. what will make that happen ?
Just like the battery on any other vehicle, connect the charger's clips to the battery terminals, red to positive and black to negative. However, because the Sportster has a relatively small battery, if charging at a high amperage (ten amps or more), it's important to monitor charging carefully unless the charger is fully automatic. Don't leave a small battery charging at a constant 10 amps overnight. For peace of mind and foolproof charging, I recommend using a Battery Tender, which you can leave connected to the battery whenever the bike is parked. It cannot overcharge yet keeps the battery at full capacity.
