9.6 volt dril will nor run, either with a new battery or old. All the batteries are holding a charge, checked with VOM.

The first thing to do is get your volt meter and check if there is any voltage coming from the battery and compare that to what it is stopped to be. If the voltage is ok, install the battery in the drill and try to run it. If it won't run, you've got a bad drill. Next install the battery in the charger and plug the charger into your wall outlet. There should be an LED which flashes to indicate that it is charging. If you can get a full charge on the battery (verify this with your volt meter), try it in the dill again. If the drill will not rotate, there is definitely a problem with the drill.

Is the battery light on the dash?

Doesn´t matter the miles runned.
The battery is too old. chemicals inside are not capable to hold Current(Amperes).
Yo must change the Battery by a New one with the same parameters. (Volts,Amps, Size.)
2008 from now it´s too much time for a Battery, even unused.

Sounds like the alternator is not supplying enough power, or the battery is old and not holding a charge. Connect a volt meter across the battery, start engine should read between 13.5 and 14,5 volts, turn on headlights and heater blower meter should hold around 13.2 volts, if it drops lower then the alternator is not supplying enough power. The alternator drive belt may be slack? If its the battery, you will need to get a workshop to check it.

I think that your batteries may have expired due to old age and are refusing to hold a charge.

Ni cad batteries have a shelf life and once that time limit has expired, you need to replace the batteries with new ones which will begin counting down to their expire date and also go dead.
once ni cad batteries have expired and past their time limit
nothing can be done to revive them ,they are forevermore dead and must be replaced.

that is the reason why i buy 120 volt ac drills instead of battery powered drills which are always dead by the time i need to use them and wont hold a charge when i try to recharge them.

my cordless radio phone batteries go dead after 1 hour on the phone, when they were newer,i could talk for 4 hours and still have 1/4 charge left. soon they will only last 30 minutes and need a 12 hour recharge to come back to 4 bars.
so i expect to have to pay 4 new batteries by christmas.

One other option may be that your charger is not working properly and developing the required voltage.
that also happens but not as often as dead batteries that wont hold a charge.
if you have a radio shack nearby, even if its a 20 mile drive
they can test your batteries and also test your battery charger. just ask for a salesman that has a battery tester and a vom [volt,ohm,milli amp meter] also called a multi meter. The vom will test your charger and came also test your batteries, but most salesmen dont know enough about the vom to use it as a battery tester .

PS a battery tester is just a vom scaled down for battery testing only, made easy to use for dummies.

To check and see if the alternator is charging, you use a VOM meter to measure battery voltage. Should be around 12 volts with engine off, and 14 volts with engine running.
You can also take the car to an auto parts store or take the alternator off and have the parts store bench test it.
You can NOT check an alternator by running the engine and disconnecting the battery cable.

Are you sure that the alt. is charging? I would check connections at alt.

use a vom/ meter on current setting put in circuit ..take hot off battery attach one lead to bat + the other lead to heavy cable u just disconnected. but 1st charge bat to full. see current draw. start to pull one fuse at a time till current drops. that circuit is the culprit. then youll need to find out why is drawing w/ bike off. wire chafed ? minor short.. or when running meter on battery 14.5 volts not running 12.5 volts if the vovtages don't go up when running regulator or altinator is bad or bat wire .. get the manual.. a big help...

CHECK BATTERY CABLES MAKE SURE THEY ARE NOT CORRODED AND LOOSE.ALSO CHECK BATTERY VOLTAGE.SHOULD BE 12.6 VOLTS IF NOT REPLACED BATTERY.BEFORE REMOVING NEGATIVE BATTERY CABLE TURN OF RADIO FIRST.AFTER INSTALLING NEW BATTERY.WITH ENGINE RUNNING CHECK ALTERNATOR OUT PUT AT BATTERY SHOULD BE 13.5 TO 14.5 VOLTS.DOING THIS WILL MAY SURE BATTERY GETTING GOOD CHARGE.2 REASON BATTERIES STOP WORKING.THEY FAIL FROM OLD AGE AND ALTERNATOR CHARGING SYSTEM NOT WORKING.IF BATTERY CABLES VERY OLD I WOULD REPLACE THEM.THAT WILL HELP BATTERY GET BETTER CHARGE.OLD BATTERY CABLES PUT A RESISTANCE ON CHARGING CIRCUIT CAUSE ALTERNATOR WORK HARDER TO KEEP BATTERY CHARGED WHICH WILL SHORTEN THE ALTERNATOR LIFE.

Like all batteries after a while they go bad/will not hold a charge. especially the kind that is always plugged in/always charging, like electric shavers, cordless vac and so on.
get a new battery
