I have been working on a vex iq robot lately so I charged my battery all night. I plugged it in the next day and it did not work in the brain. The brain showed no signs of working even though it was charging. Would anyone know how to fix this? Thanks.
If the battery failed to charge, then the charger should had indicated the issue with a red blinking light.
Instead of solid red, which means charging.
If you do have a red blinking light on the charger,one solution is to connect the battery to the brain and then connect a motor with a gear or wheel, rotate (fast) the gear/ wheel for about 1 minute, note the brain light will flash. Then battery can be charged again like normal. If this fails, please contact firstname.lastname@example.org
