It means the battery will operate a device for 8 hours before recharging is needed.
It charge faster
well, i don't really get your mean, if your lithium battery declines, you can replace it for a same capacity, working volt, and the part number.
Battery mass is not designed to deplete over time. However, some older and serviceable water filled lead batteries did require periodic fill. In these batteries the loss of water would affect mass. Modern and sealed batteries should and will not change in weight.
.... until all the hydrogen is depleted.
You'll need an external power source (such as a battery charger or another car hooked to battery cables) in order to start your vehicle. A battery which is truly depleted - not just discharged - will not take a charge from the alternator, and will need to be replaced.
No. Their battery will be slightly depleted
It means that your device's battery is dead. It's a warning that the battery MUST be replaced!
6 hrs. if the battery is fully depleted
No, your battery supplies power to the starter. However if your alternator is defective then it will not supply power to the battery and the battery will soon be depleted.
Cotton depleted the soil in the American South in the 1800's, if that is what you mean.
The battery stores just so much electricity. The lights use this electricity. Sooner or later the supply is depleted.
It can take up to 30 minutes depending on how depleted the battery is.
Battery cycling is a process in which a battery's charge is entirely or nearly depleted, recharged, and the process is repeated. In your case, the battery is not designed to do this for safety reasons, presumably battery explosion. As long as the battery is constantly being recharged by the alternator of your boat's engine and not cycled, you have nothing to worry about, aside from standard precautions and preventive maintenance.
No set answer to that. it depends on the capacity of the battery and the power drain of what the battery is connected to.
The electrical energy provides power. When the chemical energy is depleted, the battery will not longer generate electrical energy.
The Battery? No, not typically the battery. That means that the alternator is not charging the battery and IF the engine is running, it's getting all of it's electrical energy from the battery. It means that once the battery charge is depleted, the engine won't run again until you recharge the battery.
