Most likely because there is no charge going into it. Check with a volt meter while it is running. Even at idle you should have a little over 13 volts, at 2000 rpm should have 14 volts. What kind of bike?
A car battery would keep dying because inversely, the lesser the battery is used, the dying process continues. The more the battery is used, the lesser the dying process. But the dying commences and continues , the moment the car engine is not used. Thus, as often as the car is being used, the dying "resumes" the moment tne engine stops. And the faster it is used again, the slower the dying process.EVerytime the car engine is used, the battery recharges, thus life is given back to the battery. Once the engine stops, the dying resumes. This is why the car battery keeps on dying (everytime the car engine is not being used)
Dead cell in battery or something is on pulling power from the battery.
The battery should start getting a charge from the stater. So you have power to run the lights and keep the bike running. Also so to keep restarting the bike.
To keep your e-bike battery warm during winter, store it indoors when not in use, use a battery cover or insulation, and keep it charged regularly. Avoid exposing it to extreme cold temperatures for extended periods.
Dead cell in the battery or some light non vehicle is on. Can also be a stuck relay.
No way possible...
how old is battery? Perhaps cannot keep a charge Excessive parasytic load? Accessory (glove box light) left on accidentially? charge it a long time
The battery may have a dead cell and need replacing. You may also have some light that is on or a relay that is stuck.
loose or dirty terminals?
