No, completely discharging a lithium battery will damage it significantly reducing its ability to hold charge. However a lithium battery that is discharged to just a few percent of completely discharged before being recharged will get more successful recharge cycles than one that is recharged much earlier. Its a somewhat tricky balancing act and I have destroyed a few batteries myself by not stopping the discharge soon enough.
i normally do, before recharging
When the battery looses it charge. It is designed to be run completely down before recharging.
It means the battery will operate a device for 8 hours before recharging is needed.
No. Lead Acid batteries should be kept at full charge for best battery life. Constant partial charging is best.
this will lengthen the batteries' lifetime.
No, the charger should not cause harm; but it will waste mains power.Rechargeable batteries should be allowed to be almost fully discharged before recharging. Recharging a partly charged battery will shorten its life.
No, it is not necessary to fully discharge rechargeable batteries before recharging them. In fact, it is better to recharge them before they are completely drained to prolong their lifespan.
Its good for it. Any device with a chargible battery is better off letting the battery run all the way down before a recharge due to the fact that battery's in general have a certain ammount of charges they can do before it gets worn out. So yes, it is good to charge a completely dead battery then starting to charge half way.
It all depends on the motor and battery that you use
battery operates this player in full video playback mode before charging is required is 4 hours.
Yes why not, you can recharge your truck PC by driving around. To recharge the PC first the truck battery should be charged. Driving recharges truck battery because every truck has a power generator inside it but you cannot recharge your truck battery if it is not working properly the acid level of the battery should be maintained properly. Better you check your battery before recharging battery.
Recharging a dead battery by using jumper cables connected to another vehicle is a very bad idea. You are overworking the alternator on the donor vehicle and can very well destroy that alternator. Recharge a dead battery with a battery charger and never with another vehicle.
