After days of continuous use driving timberlock 4" and 6" screws where the batteries had to be recharged when they were still approx. 1/2 charged, because power started to run down,I find my batteries have no power and recharge in about 10 minutes. What did I do wrong?

battery life depends on 2 things
the amount of time you spend on the phone and the number of apps you are running
and the level of charge at which you recharge the phone
Recent questions put to a phone repair shop got the answer that 3 days from a fully charged battery was exceptional as most only do 1 day on normal use and less if watching live streaming
as to the level at recharge , batteries have a habit of developing a level memory and will not charge past that point
So if you continually recharge at almost flat, and allow for a full recharge , you get full battery life
at the other end of the period , if you recharge at say 75% charge , the battery memory starts and then it doesn't matter how long you charge the battery for , it will only charge 25% which means you wind up with a flat battery more often
so how to overcome the problem---the more you use it the quicker the battery runs down and when recharging always allow the battery to be less than 5% charge before recharging it ( dead flat is best) and leave it on charge for the max amount of time ( overnight is best)
Sounds like a faulty charger.have you tried using another charger.have you also tried running the battery completely flat via control panel utilities.sometimes this helps the battery renew its stamina by complete discharge then doing full recharge.lastly if the charger is not faulty and you have tried full discharge and recharge cycle it could be the battery is starting to fail.it is not a good idea to leave the battery on continual charge as this can shorten its life.most batteries last between 500 to 700 recharge cycles before they start to lose their holding capacity.
Based on the symptoms I would suspect a failed lithium battery. Most people think they should keep their lithium batteries at 100% but that actually shortens the life (number or recharges). I always suggest that you should try and let your laptop run down to 50% before recharging. Leaving a laptop constantly plugged in results in the same outcome - constant recharging of small amounts so you can see that the 'life cycle' is related to the number of times you recharge and if you are constantly doing it then you will most likely be shortening the battery's useful life. Unfortunatley most laptops will not run without the battery so the user's only option is to run their laptops on battery and not plugged in to AC until at least 50% dissapation thus optimizing the battery.
Just in case you have not done this, try removing and reseating the battery. Jarring of the laptop can somtines alter a good connection but from what you said it is unlikely.
Continuous over charging can shorten the life of the battery.
laptop battery is more than 3 - 4 years old then the battery could be worn out.
Rechargeable batteries have a finite number of charge and discharge cycles and
will lose their charge capacity over time, i.e. won't charge to 100% and
gradually the charge reduces until the battery won't charge up at all. OR The
battery shows a 100% charge but when the adapter is disconnected the battery
drops off to zero capacity in a very short time. If the battery drops to an
unacceptable charge level then the battery needs to be replaced.
Rechargeable batteries will fail if stored in a
discharged state for long periods.
by keeping the player constantly plugged in when of will have seriously shortened the battery life, rechargeable batteries ( exept the very latest ones) perform best by charging then using until fully discharged and charging again. this will ensure your battery lasts a long time, constantly charging a half charged battery will shorten the batteries life.
Rechargeable batteries do have a life, and it can be shortened with misuse. Order a new battery. Make sure to charge it completely before you ever use it. The first time you use it make sure you drain it completely before recharging it. This is vital to giving your new battery a good life.
if you use the lcd screen a lot, which i know i do, it really shortens the battery life. good to carry extras, NimH batteries have a shorter life but can be recharged 100s of times.... try different sets and let me know if any particular set gives you less life than the others. Sometimes NimH batteries go bad, usually the charger lights will reveal this when you go to charge them... but one bad battery will greatly shorten the battery life. you are lucky the camera gives you the option of using either, so you could, say you were at disney world and your nimh were dead, pickup some AA to get you thru the day. rsvp ;)
