Battery problems New battery keep going dead after riding 600 cbr f3 1997?

After you start the bike put the headlight on high beam. Rev the engine and the light should get a bit brighter. If it stays the same or dims the battery is discharging.

If you have a meter, take off the seat and start the bike. Place the meter in DC Voltage mode and place the red probe on the + side of the battery and the - probe on the negative side. It should read 12v to 14v. Start the bike. The voltage should rise to over 13V or at least higher than it read when the bike is not running. If you rev the engine the voltage should also rise a 1/2 volt or so.

If the voltage remains the same or decreases you have a charging problem. Here are the two most likely fixes.

Tighten the battery connections.
The rectifier is not working. It is located on the right rear of the bike under the seat fairing.The rectifier converts the AC voltage coming out of the alternator to DC voltage which is what the battery needs to stay charged.

You either have a bad stator or regulator/rectafier
