You have something draining power that should be switched off, or a short to ground in the wiring. If you disconnect the battery it will probably still be charged in the morning.
Someone would need to pull fuses and disconnect components to find the power drain while watching the battery with a meter.
your charging system is working okay or you would have to have it jumped more than once a day.you have a bad battery that needs replacing as running it during the day the charging system keeps the battery charged up enough to work.you could have a drain on the battery from something in the car that is not shutting down that you will have to have checked out.or sitting over night the battery runs down to the point that it needs to be jumped started if its an old battery(over5-6years).
First get the car running.. then with the car running disconnect your battery... if your car dies then your alternator is bad if it stays running then alternator is good.. and you probably have another bad battery... make sure your battery connections are tight. and have the battery checked if all this is good then you need to further inspect your battery lines...
if the battery holds the charge for a day or 2 wile you drive the car normally then you should check your alternator
live the car 2 or 3 days after the battery was charged and check if it starts and run if it does run it another 2 or 3 days and see if the battery dies if it dies most likely your alternator is bad, your mechanic can test it with in 3 minutes to see if it is the alternator or the battery
In most cases when a battery fails to take or hold a charge it usually means the battery has "lost" cells and the battery is no longer viable. Running a lithium ion battery down to very low and then charging it back up is very bad on these laptop batteries. These batteries do not get a "memory" like in the old days, these you can leave on the charger all day and it won't hurt them....but running them down and then charging them up will shorten thier life expectancy.
Hi Cindy
slight possibility of a short in the battery cell,
I would also check all the wire connections to the battery. and all the fuses and their connections.
You didnt list the bike, but generally if you place a volt meter across the battery it should read just over 12v with the engine stopped, not drop much below 12v while the starter is cranking, and rise to around 14v with the engine running. Tandy will have small multi meters for around $10.
If you remove the battery, check it is filled to the recomended lines, and look if there is any whitish deposits you can see through the casing, this is what can short a cell.
If the battery is a couple of years old it may pay to just get a new one. If there is a cell on the way out, and it shorts completely, it can put extra load on the bikes electrics. Stators and regulators are far more expensive than a battery.

lights on motorcycles are not like scooters, they run off the battery. In the old days they had a separate switch, now they turn on immediately after ignition key is on.
