Why dose my Kindle tale a long time to charge
Every time I charge my Kindle it takes hours to charge why
Is this a good question?
Updated version of the Kindle Fire 7" tablet by Amazon with 1280x800 HD display. Released September 2012. Repairing this device is straightforward.
It's all in the maths. Your Kindle Fire HD 7" has a 4000 mAH battery.
If you are using the charger that came with it, it has a 1000 mAH output.
As a rule of thumb, not quite strictly true but close enough, with these figures it could take up to 4 hours to charge the battery from flat to fully charged.
(4000 mAH divided by 1000 mAH = answer in hours)
A lot depends on how low the battery was when it was started to be charged and also its' age. The older a battery gets (the number of times it has been recharged) affects its ability to fully charge and to hold its' charge.
If you were charging it with a PC connection (500 mAH ) then it could potentially take up to 8 hours to fully charge. (4000 mAH divided by 500 mAH = answer in hours)
Do not be tempted to charge using a charger with a higher output voltage and/or current than what is recommended by the a) battery manufacturer and b) device manufacturer, as the battery could overheat and either be damaged or even explode or start a fire.
