it means that you can't charge the battery and you need to replace the dead batteries with new ones
Not a good sign, This could mean that your charging system (alternator) isn't doing its job. If you have problems starting the car due to not enough battery power, then check your battery to see if it is holding the charge. If after a while that you had to boost or jumpstart your battery your car gradually dies then check your alternator to see if it is putting out charge to the battery.
A battery that has lost it's charge.
Possibly a bad alternator (the system is not charging the battery).
It probably means your car is cheap and broken, or that people did alot of test runs on it in the car dealership. -------------- It might mean that there is a short in your car's electrical system, or that your alternator is not working and is not charging the battery. It could mean simply that you did not fully charge the battery, and that yours is a newer car that draws charge continuously to power components with memory.
Do you mean charge by the vehicle running....or do you mean take a charge from a Bench charger? if its in the vehicle it could mean that either the battery/battery connection/cables, a faulty ground, or the alternator is defective. If its on a bench charger then the battery has a dead cell or is defective and needs replacing.
you need to charge it
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.
I assume you mean if it is stored. It depend on the battery and what condition it is in. A good auto battery will hold it's charge for at least 6 months.
There is a good chance that your alternator has stopped working. It could also be just a loose wire from the alternator to the battery that is not letting the battery charge. Also it could be a bad battery. When a cell in a battery dies it will hold a charge for a short period of time but then rapidly die. Get the battery checked first. they the wires, then the alternator.
you mean animal jam?
I assume you mean how long to charge the battery. You should never let the alternator charge a dead battery if possible. The alternator is designed to keep the battery charged but not to charge a dead battery. You put a strain on the alternator and it can cause a diode to burn out. Drive home and then put a battery charger on the battery to fully charge it.
A multi-charge battery can be re-charged while your laptop is on or you can use the AC Adapter port to charge while detached from the notebook. An example is the HP KS526AA 12-Cell Multi Charge Extended Battery. It can add up to eight hours of battery life.
