agm capacity test
I've installed 2 8d deka intimidators in my fiver. Closing in on 15 cycles. Would like to do a baseline test so I will have something to compare to in the future. What would be the proper way to prefo...

Take the battery readings INDIVIDUALLY
Use a 8 ampere constant load. A 100 watt 12 volt light bulb works perfect for this type of test. 24.00 hour test. Time of connection is important. Try to disconnect to the minute at 24 hours on-time.
Let battery rest for a minimum of 12 hours. Then take a voltage reading.
Are both battery at rest voltage, say with .10 of one another?
This will give you an excellent COMPARATIVE reference point for future use.
Yes, it discharges the battery below 50% capacity. No a test or three will not "hurt" an absorbed glass mat battery.
Don't bother tying to play battery test lab, the protocol is intensely complicated and you'll need to sell your house to finance purchase of instrumentation.
This is a perfect "IS/WAS" comparison.
A pair of 50 watt 12 volt lamps can be substituted for the single 100 watt.
