The acceleration goes up 3 but not the car reaches 40 km / h

sounds like there might be a control module issue, might be the BCM.Alternatively, related to the same issue, it is possible your vehicle has gone into safe mode if the engine/transmission sensors have detected a potential problem it allows you only into first gear until the problem receives attention. You probably need to take it to a manufacturer's technician for electronic diagnosis I think

I have a 2003 ford focus wagon second hand. My battery died out and I thought the alternator was the problem. Brought my car to an alternator repair shop and they said the alternator is still good. I ended...

Lead acid batteries don't like being discharged flat, and it could now be damaged and unable to hold a charge. It does sound as though the voltage regulator part of the alternator is allowing discharge to ground when it should not. You would seem to have a good warranty claim on the battery given they did check the alternator and pronounce it OK.

Car wont start but the lights, radio and everything battery operated comes on but it just makes a click noise when trying to start engine

If you can hear a click (quite loud) from the engine compartment, but the starter won't crank, this also could be caused by discharged battery. Battery problems - Discharged or dead battery is one of the possible reasons for a car not to start. Very common is the situation when we forget to turn the lights off overnight (the dome light, for example), which causes the battery to drain. In this case when attempting to start a car, all you will probably hear will be a clicking noise - there won't be enough power to turn the starter. Here is the simple way to check if the battery is discharged: Turn the ignition on. With the engine off, turn the windshield wipers on. If they move way too slow, much slower than usual, the battery is probably discharged. Also look at the dashboard lights - if they appear very dim, the battery is probably discharged.
If the battery is relatively new, it can be recharged. All you need to do is to boost your car and let the engine run for a while to charge the battery.

However if your battery is more than three-four years old, you will probably need to buy a new one. Sometimes, an old battery may even die with no apparent reason, even if the day before it was OK.

If the battery is OK, the starter solenoid, starter cables or the starter motor itself could be a problem.

Check it and tell us news.

Something is draining our battery and it's not the alternator

It sounds like you have a wire that is going to ground. It is drainning the charge out of the battery. It has the same effect as just like leaving your lights on all night! It sounds like you have a pinched wire under the dash since you said the CD player quit working. I would have a car stereo technician see if he can find the problem. It will most likely be under the dash possibly one of the wires going to the CD player. The problem with starting when cold is that the oil in the engine is colder and harder for the engine to turn it over. When the engine warms up it probably isn't as hard to star. You need to fix the "battery drain" that is discharging the battery and you may have to replace your battery. Automotive type batteries are not designed to be near or completely discharged day after day. The battery is used primary to crank the car. When the car is being started it uses most of the amps in the battery. The type of battery in a car is designed to use the voltage in the battery at cranking and then have the alternator recharge it when cranked. When it is colder, more "C.C.A."s or "Cold Cranking Amps" are needed to turn the cold engine over. When purchasing a battery, try and get the most "CCA"'s as possible. It will be listed on top of the battery. For instance, a 625 CCA is not as strong or will last as long when cranking as a 825 CCA battery. I would have a auto parts store or technician to do a "load test" this will check the battery for its strength. It simulates a load on the battery and tells you if it is good or not. It sounds like you have a "top charge" on your battery. This means that if you put a meter on it, it reads 12 volts. But if you try and crank the auto,watch the meter, it may drop to 9 or 10 volts then when trying to crank and then the voltage may go back up in a minute or two. The battery looks good but is not. Most engines wont start with that little of voltage.

key off and out,diconnect negitive side of battrey then postive.clean terimals,charge battrey,connect postive cable (with key off)connect negitive.and start.
your dead battrey is taking up a big load on system,so when you boost it the dead battrey is taking it all the starter is geeting vey little.thats the clicking.
if you dont have a charger dicconect both terminals the same way again,put the jumper cables on the dead battrey.let it charge battrey for 10 15 mins .the longer the better.remover jumpers.
with key off and out conected battrey terminals.connect jumper cables and start.
let me know if it start or not hopefully the key hasnt lost its coding.
