Recommended Instrumentation
10-40 Watt Light Bulb
Wattage needs to be accurate.
The purpose to quantify the discharging of a charged battery. Possible source: auto parts store, local auto mechanic's shop. Be sure that the discharge rate is within the battery's factory-specified recommended rate (not discharing faster than recommended).
(e.g. Ancor mini lamp #1142, Volts: 12, Amps: 1.44, Watts: 18.4)
Multimeter
For measurement of voltage and amperage.
$14.99
Variety available from PowerWerx
Battery Capacity Analyzer
: "We use a very special meter to determine the charge in the secondary battery. That meter is called a BK Precision Battery Capacity Analyzer, Model 600." -- John Bedini, Oct. 20, 2004
BK Model 600 : "12V Sealed Lead-Acid Battery Capacity Analyzer"
: B&K Precision model 600 measures the storage capacity of 12V Lead Acid Batteries and displays the batteries capacity as a percentage. This can help identify batteries, which may be defective or deteriorated.
: Pulls just over 5 amps for less than a second. Non-test load, for digital display is 100 mA.

Computerized Battery Analyzer
$109.95
"Test virtually any type or size of battery, any chemistry, any number of cells up to 48 volts."
Up to 40 amps or 150 watts, whichever is higher.
Tests the total amount of energy stored in a battery (capacity in AmpHrs)
Software provides automatic sensing of the battery cell count, a safe maximum discharge current and recommends a minimum safe cutoff voltage
Plug-and-play USB interface to the computer.
Software, supplied with the CBA, is easy and intuitive
Graphically displays and charts voltage versus time
Constant current load is controlled both with software and electronically.
Graphs may be displayed, saved and printed.
Multiple graphs of the same battery, or multiple batteries, may be compared or overlaid.
May be printed on a color or black and white printer.
CBA will even measure the temperature of a battery using the 'optional' external temperature probe.
Tools:Review:West Mountain Radio CBA : Probably a defective unit. Will return for replacement, per manufacturer's suggestion.
Load
Some means of discharging the batteries over time within their rating.
Odometer
Tools:RPM - optical tach, multimeter option, makeshift oscilloscope, etc.
Compass
To be able to detect the North pole of the magnets.
Gauss Meter
Would be good for documenting that any effect is not coming as a result of the degaussing of the magnets.
