Put a test meter on the end of the D-cell battery
Any one using a voltage test instrument can measure charge differential voltage.
A battery may have a small voltage potential but not the "CAPACITY" to deliver amperage. For instance if you were to measure the voltage at the battery terminals with a Volt/Ohm meter (VOM), you would get a reading of say 12+ volts. As soon as you turn something on such as a headlight or heater motor, the voltage drops down or goes to 0 volts, you would have a battery that is bad or under capacity. It also could be caused by a "BAD CONNECTION" such as a loose battery post clamp. It is critical that when you test a battery, you test it at the battery posts themselves without the cables attached to rule out a bad connection. This is done with a battery load tester. As many people do not have the equipment to test a battery, batteries can be tested at many automotive parts retail outlets across the country for a free charge.
A sweep test is a method that determines the frequency response of a cable by its generation of RF voltage. This frequency should be varied at a rapid constant rate.
A hand held test meter is usually rated for 1000 volts.
Some test instruments used in electronics are:Multimeter - Used to measure voltage, ampere and resistanceOscilloscope - Used to measure frequency and oscillations
with batteries and a knife
A battery charger can be used to test a battery if the charger includes a voltmeter, so you can read off the voltage. Note: A battery charger is designed to be used only for rechargeable batteries. It can be very dangerous to try to use a battery charger to test or recharge normal non-rechargeable batteries.

The test equipment used to test high voltage cables is a hi-pot test where a high DC voltage is a applied to the cable. This voltage can be from 150% to 200% of the working voltage of the cable.See related links below.

Take it to anyplace that sells batteries and they will test it for free.
auto parts store it measures the voltage of the battery and has a load of a reasonable size so voltage has some correlation to charge state. when batteries had external posts you could check them one cell ata time and know which cells to add water to now to test battery a cell at at time youll need to get a hygrometer theres one with assorted plastic balls of different densitys. about $1 and much better than electric test . there are some batteries now that are sealed so throw those away if the auto parts place wont give you $5 for it for a 9volt battery lil bity one you can get one at radio shack this can also check cells, has load resistors for AAA AA C and D.
It is the rated test voltage that will not cause insulation breakdown.
Under load, take your voltage meter and read from the first battery - terminal to each successive + terminal. Each increase in voltage should be the same for each battery. Anything off by more than .3 volt is starting to deteriorate and should be reconditioned.0- ____ +6.2 -____+12.4 -____+18.6 -____+24.5-____+30.2-____+36.4.....#1 ..............#2 .............#3 ...............#4 .............#5...............#6Battery 4 is marginal, Battery 5 should be reconditioned.Of course, the difference should be less for smaller voltage batteries and no more than .5 volts for 12 volt batteries. These are just numbers I have come up with empirically. Someone else may have a better reference for the allowable voltage difference between batteries in series.
No this is not normal. The first thing I would do is check your test meter against another one. See if a friend has a tester and ask if they would check your voltage. Make sure the batteries in your test meter are new and fresh. If both test meters read 133 volts on your house wiring then its time to give the power authority a call and get them to come out and check it.
Random sampling is important because it is much more practical to test a small group of results than a bigger whole. Say, for instance, a company wants to test the average voltage of a battery they manufacture. It would be much more practical to test 1000 randomly chosen batteries than to test 100000.
