Why has my peugeot 406 wipers stopped parking? They just stop randomly

You clearly have a leaking power problem.
1) first check if the battery finaly died and can't hold proper voltage. If it is having 12V just before starting but drops fast a new is required.
2)This may be a long shot but give it a try. If one diode in the generator is broken you might see this kind of problem. With the battery fully charger try to disconnect the generator. Take care for shortcut of the cable taken off - it is still plus from battery. If the problems dissapear then the generator is ready for a being reworked. Do you know why the battery vent flat? if not this can be the same reason. With only one faulty diode the generator will still do some chargeing with engine running.
PS: while working with generator cables it might be a good idea to disconnect from battery until cable is secure garfa'ed.

Battery charger issue

funny thing with batteries is that they can get a memory = sounds stupid yes = if a battery is recharged when it has half charge and then fully charged it remembers the point , one it gains memory it wont charge past the last point = or the battery life is over = or the charger is faulty.

Hi mine show fully charged drilled 1 6mm hole and went flat yet sometimes is ok

Try fully discharging the battery first and let it sit for a few days. Then fully recharge before use. What happens with battery operated drills is the batteries develop what is called memory of the charge level when they are recharged and will not charge past that point but the charge light will show full charge. It happens when the drill is used for a period of time and then the battery is placed in the charger ready for next time instead of using the drill until it is flat or leaving a partially used drill on the bench and not recharging it until it is flat

When to recharge batter

hi right to be honest both ways are correct, but if your using it every day then its best to put it back on the charger after every use, but the problem with this is that the battery never goes totally flat, so never does a full recharge this reduces the life of the battery by upto 50% so if you are using it regular and need it charged daily then its best to once a month let the battery go totally flat so that it wont even make a sound then do a full recharge.
Doing this will ensure the battery remains at peak performance and make it last longer.

If how ever your only using it say once a week then its best to only charge after the battery has gone flat due to the fact that it would remain on charge longer and cause the battery to over heat reducing the life span of the battery.

But witch ever method you use always let the battery go totally flat once a month then do full recharge this will prolong the life of the battery and ensure it keeps working at full power.

Let me know if you have further questions ok

My JVC car stereo will let me listen to the radio but when i put in a cd it wont play and 00:0000 AY flashes constantly. It started a week ago... have i pressed a wrong button?

I had the same problem, it occurred after my battery had run flat. To fix it you need to reset the unit. To do this, remove the clip-off fascia, and on the main body of the unit there small hole, just to the left of the connector. Push a narrow pointed object such as a pen nib into this hold until you feel the click. The unit is now reset and should be working properly. You'll have to retune your saved radio stations, but the cd player should now be working.

I have a battery charging problem on my Gateway Solo1450 laptop. The battery is new and gave me 30 minutes of battery only run time after taht it would not charge. I set the commands (Enabled) in the BIOS...

hi, if the battery is new then you need to start looking at things like the charger. If the old battery was used for a long time, and as they have only a few months life span then this puts extra work on the charger due to the fact that when the battery is new it holds its charge and recharges fully now the problem is when the battery is old it dont hold the charge and runs flat alot quicker so this puts extra strain on the charger is its trying to charge a battery that wont charge properly as well as keeping the laptop working. This tends to cause problems with the charger due to it over heating so this is what i would look at first.

The second and less likely cause might be that due to the old battery over heating due to it not holding a charge this may have caused some components or solder on the circuit board to fail this isnt very likely but does happen from time to time.

What i would do first is take your laptop and charger into a small computer repair shop and just say to them you dont want any work doing but is their any chance you could tell me if my charger is working or not, play it like if i need a new charger youll buy it from them or if they say the board is damaged just say to them that you will bring it back when you have the money to pay for it. This way your not obliged to leave them with the laptop and you will then find out the fault for free. At least if they say its the charger then you could then get it off auction site instead of the computer shop.

Let me know how you get on or if you need further assistance.

Try this first though use the laptop untill the battery is totally flat i mean flat so much that it wont even light the laptop up then without using the laptop plug the charger in and then leave it to charge for say 12 to 16 hours so that its had chance to do a full charge from flat this then may solve your problem.

Also doing this process every month will ensure you get maximum life out of your battery

Batteries are going dead within 5 min

What type of rechargables are you using? Ni-Cad are reputed to have a 'memory' so that if recharged whilst not fully run down this is accumulated so that only the new bit of charge is 'active'. So-put the batteries in a torch and leave it on until the batteries are completely flat, then recharge. And/or get a couple of sets of Ni-Mah rechargeable and a suitable charger and start afresh.
