[RE-wrenches] Battery at temp

[Darryl Thayer]

Yes when the battery is colder you adjust the readings lower, My old fashoned 
hydrometer shows state of charge for different SpGr   for example at 20 below 
the 50% state of charge would be reduced to perhaps 35% SOC

Per the HUP Solar One owners battery manual:
 
“The normal operation temp is 77-80°F. Lower than normal temps. will reduce 
capacity, slightly extend life, require a higher recharge voltage, & cause SG 
readings to be adjusted down. HIGHER TEMPS HAVE THE OPPOSITE EFFECT”.
