Phone holds charge from 12-55 min. and then goes dead

Quite probably it's the battery. Open it, get the specification for battery and buy a new one. Be careful, there are many very similar batteries but connection to phone is different.

With your phone powered on, connect the charger to the phone. With your phone unlocked, press and hold the END key to power off your phone. The phone will now shutdown and then restart to the charging screen. As soon as you see the screen with the battery and the word "Charging..." under the battery, press and hold the END key to power on the phone. This must be done before the phone has a chance to display "No Battery".

check under the battery is there a little pink/red circle

hi

have your alternator tested

try to buy a new battery for that and keep your phone to lock so that it wont open their lights everytime your not using it.
another tip: drain your battery before charging it and make a full charge after you use it. hope that helps

No solution.  The battery was dead, and buying a new one would have cost more than the cost of a new telephone.  So I bought a Sagem ....

It sounds like you have a defective battery. Usually when batteries won't hold a charge for very long, then it's time to replace them. Was the phone brand new or used ? If it was used then I am surely gonna say battery, but if it was brand new then it might be something else. I would say that I'm 90% sure you have a bad battery. Hope this helps solve your problem.

Try this:
Pick a handheld, press Menu - H/set settings - Reg Handset - Select Base 1, enter 0000 as password. Now on the bottom of the base station press and hold the Register button in for about 10 seconds or until the h/set beeps.
