This is related to this question as well, in which I inquired about the most appropriate float voltage for a battery that would be in very high ambient temperatures, as the float voltage should compensate for temperature changes to avoid over-charging.
A question I'd asked in the comments, and was recommended be a separate question here, is the following:
What compensation is appropriate for the cut-off voltage of a sealed lead-acid battery? If ambient temperature is 130-140 degrees [inside a vehicle], and I'm lowering the float voltage by .5Volts to compensate (0.003mV per cell per degree celsius over 25°C, 30°C difference to 55°C)
As an example, if my cut-off voltage would normally be 10.8Volts for a deep-cycle battery at 25°C, would that value be lower for a battery in an ambient temperature of 55°C? If so, how much / how would I calculate the compensation?
Tagged as battery charging because I wanted to tag as battery discharging and there wasn't one for it... feel free to edit if there are more appropriate tags.
