Proper Electrolyte Level

I have been working to get my SOC back to factory specs, following the advise on this and other forums. Specifically raising AB time and AB voltage. My SG's are close to 1.27 but the fluid level is about a 1/2 inch below where the manufacturer wants the fluid to be. Do I add more water, dilute the SG's and keep charging, OR is the fluid already at the "right" level?
Thanks.

    Hey mvas
    Too early in the year to be gob smacked like that. But if it's that simple, I like that.

    Assuming the battery is fully charged and the SG is as high as it will rise, this would be the time to add water to the correct level. Note: Adding water will lower lower SG readings as the water and acid will be stratified, an EQ will mix the electrolyte and bring the water into solution. That being said the EQ will raise the temperature of the electrolyte and SG readings will be offset and will need to be compensated for, the EQ  voltage should also be reduced as temperature of the battery rises using a remote temperature sensor. After cooling and no loads, say overnight, take your SG readings. Alway follow the manufacturers recommendations as not all batteries are alike, age is another factor which affects readings.
