it could be a bad battery or else something is drawing power from the battery
get the battery checked at a auto parts shop most shops will check your battery for free while you are at it get them to check the alternator is charging properly also
once you know its not the battery or alternator At Fault put an amp meter in series between the battery positive and the positive wire of the vehicle with everything switched off you should only get a reading of well below 1 amp(because of clocks and radio memory etc there will always be a small draw) anything near or above one amp is too much of a draw if this is the case start removing fuses one at a time replacing each one as you go until you find one that causes the amp reading to drop to well below one amp then check what the fuse is for and it should lead you to the fault

No, a starter cannot cause a battery to fail to charge. It could cause the battery to discharge quickly.
An auto battery could be leaking for a couple of reasons. The alternator could be overcharging the battery causing the leakage. Or the battery itself could have a short or other internal problem causing it to leak when charging.
A short in the car's electrical system, a bad alternator OR a bad battery.
If your cell phone will not charge it could be the battery or the battery charger. You best way to find out is to try the battery charger on a similar phone and see if it charges the other one.
The obvious answer is that your battery is bad and does not hold a charge. This happens to all batteries in time. Often, before they die completely, they run down quickly and only hold a charge for a few hours. If you have a new battery, something, no doubt a short in you electrical system is draining your battery.
the battery could have a dead cell, this could cause it to not charge. Have the battery tested to be sure.
If the starter is "clicking" then check the battery to make sure that is has enough juice to turn the starter. If the battery is good. It could be your starter solenoid is bad. Most of these are built into the starter nowadays. You will have to have the starter changed. I am betting on the battery especially if it is older. Another culprit could be your alternator failing to charge your battery.
If the battery is worn out it may not hold a charge for 8 hours. There could also be a short somewhere causing the battery to drain down.
Loose or worn fan belt would cause alternator not to spin fast enough to charge battery. Worn bearing in alternator could be causing it to seize and causing belt to slip
Do you mean that you can not charge it with a battery charger or the mower will not charge it while it is running? If you can not charge it with a battery charger and you are sure that the charger works then the battery is bad. These type batteries are only good for a couple years. If the mower is not charging the battery it could be a number of things.
You can start a car without a battery if you hook up a jump pack or use jumper camples but it could fry your alternator. It is pointless to charge a car without a battery. When you charge the car you are charging the battery.
