My 99 vt750c 's barttey is going dead every two or three days. new batteries all do the same. i know it's a charging problem but were do i start?. can any one help me with this.? thank you. ibserendypyty @ aol. com

16.3 volts is the high side of the charge rate and will result in boiling the battery dry. Have a load test done on the battery as I fear you have a dead cell that is not holding the charge

If YOU CAN DRIVE IT,GO TO aUTOZONE,THEY WILL TEST YOUR ALTERNATOR FOR FREE,TAKES JUST A FEW MINUTES.

Dead battery armed the security system. Remove the battery cable let the system reset. Charge the battery. Use the key to unlock the door instead of the keyless entry. This resets the alarm once the battery is charged.

Try getting new switch. Check bad spots.

battery might be dead. if yours is a new system then i suggest you go to warranty claim. if it is old then bad luck replace your battery

your charging system isn't working, if you replaced the battery and it worked for a few days, then its not being re charged after starting, I'm assuming you cleaned and tightened all the battery post connections when you installed the new battery , if not do so ,, charge the battery from an outside source, once you know its fully charged,, use a meter, and start the car ,, check the voltages at the battery posts,, you should be getting a reading of 13.5-14.5 volts, if not your alternator isn't charging the battery

It seems that the issues is with the battery itself, not the cppu.

To double check, you can do the following:

1. Disconnect adapter and run battery completely dead.
2. Reconnect adapter and let charge for at leasst 12 hours OR until battery displays 100% charge.

If it still won't charge to 100%, then you know for sure the battery is defective/worn out..
If you want to know more about this, look on wikipedia for: "Laptop Battery Lifespan" or "Laptop Battery Memory Charging".

But I'd say it's safe to assume that it's time for a new replacement battery for your Notebook PC.

Hope this helps!

Hi,
Batteries can go bad... then they do not fully charge or hold a charge for long... they can short out internally...
First thing to do is to try a new battery...

First off, disconnect all those accessory wires, leave only the battery cables hooked to the battery. Charge the battery properly over a long time with small voltage input so the battery won't overheat and warp the plates inside.
The voltage after fully charged should be about 12.75v-12.80v, when you check the battery with a voltmeter.
I am quite certain that one of the accessories is drawing down the battery which is why it is dying in three days.
You might want to buy a little hydrometer made for a MC battery too, so you can check each cell to make sure there is not a dead one, this too can cause the battery to go dead in three days, because it will not hold a charge.

yeah if you have had it for that long the batteries might be dead even if the appear to be charged i would get new batteries or get a new camera get one cheap on eBay ! have a good day :)
