Xbox controller does not start

Solution 1:

chances are the battery pack is damaged internally causing a short of sorts which is known as internal discharge. With good care a standard nihm rechargable battery will often only last about 3 years before this type of problem becomes an issue. Personally I have found that my charger controller boards go bad before the internal batteries go but you seem to have had the board last longer than your batteries optimum life. if you were to throw the pack on a cement pad a few times to crack the thing open you would find that is all that is inside is two standard nihm batteries the charge controller and the contacts. Cheapest solution would be to buy the adapter to simply use your own rechargables... You may possibly be able to extend the life of the old pack still with a hand full of tricks such as fully discharging the pack and freezing it over night then charging it back up with a low amperage charger....look up rechargable nihm maintenance for more info.
