I tried to post this on "Technical Section" but I was disbarred from doing so.
With the very technical (most of the time) discussion going on about Lithium Batteries at a level that is completely beyond my understanding, I was wondering if there are SIMPLE rules for running a test on a Lithium Battery to discover where it might be in its life, regardless of its age.
I have a Multimeter (I believe it's called a 'Galvanometer type') which measures:
OHMS (X1 - X1OK)
DC.mA (.o3 - 600)
AC.V (6(17dB), 30(31dB), 60, 300, 600up)
DC.V 3 - 300
DC.mV (60 - 1200)
There are 3 'sockets' for placing the red/black probes:
- COM, +v.ohms symbol, AC1200V
I have tested my 2 Lithium Batteries after they have been fully charged (checking for any 'false green lights') and they both read 42V (or as near as my feeble eyesight can make out on the tiny scales). That is so despite the fact that one battery is 17 months old) and the other is only 7 months old).
I should say that the older battery has covered about 700 miles and the younger one about 300 miles.
Apart from riding them to the red light are the results I am getting from the above readings telling me anything useful?
Incidentally, the last time they were out performing service they each achieved 19 - 20 miles (eZee Sprint + 88Kg unfit rider - hilly route 0 - 10%) before they became too feeble on hills (like 3%) to be tolerated (red light on from time to time).
Is my 'equipment' sophisticated enough to be useful in undertaking further bench tests for significant results?
