Your battery spec data sheet will say what the resting full voltage and SG should be at 77F. do the equalize, let them rest for a day and check the SG--it will be higher next day when they cool down after the overcharge. (SG is higher with cooler electrolyte--more dense)
I read this with a bit of amusement. I am in South Mississippi and as I sit typing this my thermometer reads 97 degrees. I may have to wait until October for the batteries to cool down. The batteries temped at 90 when I checked them just a while ago. They were at 93-94 when charging. The SG on all batteries is 1.275 or a bit higher. If I understand adjusting for the temperature this should equal 1.279-1.280. Am I correct in this or do I want to see 1.280 regardless of temperature?
