about -- NiMH charging & LM308 models

NiMH Charging :: notes
charging from 12.6 V automotive 70Ah PbSO4
(a) initial current no load limit 100mA and grows fast
-- faster when cell is more empty - up2 10+ A !!!
(b) initial voltage current limit 50Ω 4W metal film
2.17V [12:23] after 2+ h charging
1.72V [15:34] 3h 600mAh 1:4-th of capacity
1.85V 190mA [17:25]
1.79V 190mA [17:50]
1.79V 190mA [18:13]
1.79 1.800 V 190 mA [19:33] 7.2h 1400mAh(200mA) 60%
1.80 1.798 V 190 mA [20:20]
1.79 1.796 V 190 mA [21:12] 8.8h 1675mAh(190mA) 70%
-- ??? so far the battery have had no heating up over the ambient
-- (whitch would indicate reaching the full charge) ??? (see *note)
1.77 1.782 V 180 mA [22:39]
1.77 1.777 V 190 mA [23:17] 10.9h 2071mAh(190mA) 78% (*2650mAh)
1.78 1.788 V 190 mA [ 0:21] 11.6h 2274mAh(190mA) 86% Label.val*
Final 1.489 >> 1.463 >> 1.340*

1.770 V 190 mA [ 0:27] start.2 *%
1.610 V 190 mA [ 2:09] 1.7h 323mAh 12%
1.600 V 190 mA [ 9:11] 8.7h 1659mAh 63%
1.600 V 190 mA [10:51] 10.4h 1976mAh 75%
1.596 V 190 mA [12:38] 12.2h 2315mAh 87%
Final 1.486* >> 1.450 >>

* note :: the DURACELL´s MODEL : CEF14KTNEU
-- INP : 100÷240~VAC 50/60Hz 8W
-- OUT : 5.6V 360mA (4x AA NiMH) / 2.8V 160mA (2x AAA NiMH)
as i remember output some 300÷320mA and heated up the AA-s
while the Resistor Ltd. charging of 190÷240mA did NOT !!!
??? are the factory chargers in purpose set to shorten your
accus lifetime ???

LM308 LT-provided & customized component level model compared ::

[BLUE : GREEN : RED] CustomCL.1 : CustomCL.2 : LT´s - .CIR

The TEST is setup to minimize the batch err. -- however never verified that this is what it actually does !!!

... minor modifications ...

===============================================

Fast / poor instrumentation mode test ::
