Modern (Lithium ion and Metal Nickel Hydride) cell phone batteries have no "memory" problems like those that plagued Nickel Cadmium accumulators so you do not have to let the battery discharge fully before recharging them. However some modern battery chemistry does improve during the first few charge cycles so the full usefull duration is attained only after some (say 5) charge/uncharge cycles.
by letting the fuel battery charge. Yes, but how do you charge the battery?!
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.
There are several things that you can do to increase the battery life on your phone and the first thing is to only charge it when the battery is low. The second is try not to charge it in your vehicle only charge it at home with a regular charger.
It is always good to charge a battery to its full capacity before it is fully charged.
No, not at all. Letting the battery run flat can sometimes even increase battery life.AnswerThis was an actual problem with early rechargeable batteries because over charging batteries would dramatically reduce their life span. However, most chargers now have sensors that detect that available charge and will shut themselves off before they reach that point.However, some companies do suggest that you periodically (once a month or so) allow the battery to drain completely before recharging it as a way of resetting it.
You cannot change the amps in an existing battery. If you want to increase the CCA you will have to purchase a new battery with a higher rating.
My advice is to charge the battery with a battery charger before starting the engine. You will be putting a heavy load on the alternator if you allow it to charge a dead battery. This could damage the alternator.
It is best to drive home and put a battery charger on the battery and let it fully charge. Letting it charge with the alternator puts a strain on the alternator and should be avoided if possible. But if you have no charger then you will need to let the engine run for around 30 minutes to charge the battery enough so that it will start the next morning. It will take a couple of hours of driving to fully charge the battery.
Add distilled water before for you charge it. Do not use tap water.
Fully charge the battery before its first use. The first 3 or 5 cycles try to fully drain and fully charge the battery.
When the alternator starts charging the battery voltage will increase about two volts to charge the battery.
You ant to charge the lithium Ion battery before the battery reaches a 20 percent charge, so when the light goes red.Charge it while you are playing so you can sit there with no battery loss
