House batteries not up to ah rating
Bought 2 new Interstate SRM-24 group 24 RV/Marine batteries a few months ago. I have used the MH 4 times on trips lasting from 3-6 days. Never going below 40 amps before recharging. The rating is 85...

bought a new hydrometer. Thought it was giving incorrect readings. Batteries spent the last few days on the RV charging system and getting fully charged reading with volts. I even used the solar panels to give it more charge at 14.6 volts for 3 hours.
New hydrometer shows sg of 12.45 on both batteries and all cells are within .05 + or -.
The volts show 13.23 and 13.25. I attached one battery to my Vector charger on desulfation mode for 24 hours.
The other is attached to the solar panels at 14.67 volts and .2 amps for 180 minutes. I want to see iff the sg goes up any. 12.45 is .30 less than TOPPED OFF, right?
Update equalizing now 15.4 at .7amps should be running 120 minutes.
