Simple question: Is low amperage good for battery? Is it decrease wear level? Ex: we have battery with 2A recommended. Will it be better to charge it with 1A?
Anything that reduces temperature rise <10 deg C results in reduced aging rates but longer charge times. So it is a tradeoff between life expectancy and Amps per Amp hour capacity. e.g. using a C/10 battery in C/5 mode improves life expectancy by x% (ref needed) if that reduces temp rise.
I^2*ESR=Pd then Pd*Rja = T_rise
- The charge or discharge current squared times the internal Effective Series Resistance , ESR = Power dissipated, Pd. Then the thermal resistance from internal cell junction to ambient, Rja, determines the temperature rise of the cell chemistry.
- Arrhenius Law says "for every approx 10 deg C rise, reaction rate doubles" which means life expectancy is reduced by 50% ( for the duty cycle at that temperature)
