It appears as if all the batteries have a cell shorted as they drop to 10.8 as soon as the charging stops. Very starnge3 thtr they all shorted at the same time.
However this means I am charging at too high a rate now and have dropped the charge voltage by 2v.
Will try and repair the batteries.

From 5th Feb the charging voltage is 13.92 so the solar input will be low. The available power could have been more than 1Kw

2. Seem to have lost the Black and Decker Found : Oct 2019 Was at Rowena's for the last few years. Though I have it working the speed control is duff and the chuck is on it'd way out,

Tuai gave me his old portable drill set, though the screw-driver chuck has a broken piece in it that requires removing before it can be used.

strong>Charging

1. Plug the battery charger into the proper AC voltage source. Charging light will flash in green color repeatedly.
2. Insert the battery cartridge into charger until it stops adjusting to the guide of charger. Terminal cover of charger can be is opened with by inserting and closed with pulling out the battery cartridge.
3. When the battery cartridge is inserted, the red charging light will light up and charging will begin with a preset briefmelody sound coming out for assurance as to which sound will come out to notify the completion of charging.
4. With finish of charge, the charging light will change from red one to green one and the melody sound or buzzersound (a long beep) comes out to notify completion of charge.
5. If you leave the battery cartridge in the charger after the charging cycle is complete, the charger will switch into its“trickle charge (maintenance charge)” mode which will last approximately 24 hours.
6. Charging time varies by temperature (10°C (50°F) – 40°C (104°F)) that battery cartridge is charged at andconditions of the battery cartridge, such as a battery cartridge which is new or has not been used for a long periodof time. 7. After charging, remove the battery cartridge from the charger and unplug the charger from the power source

Have emptied the electrolyte and fished the cells with a hose, filtered the electrolyte and replaced it.

The battery was at 6.54V and have now connected it to a single 250w pv panel and am monitoring the voltage. There is no controller so the max current will be around 8A

24th January :: ML V=10.49↖ Y=130Wh What happened to the voltage ?? I was away all day so no usage to speak of. Was fine whne I left around 10:45 am. Some 12 hours later when I returned the system ahd shut down, the voltage being less than 11.

In checking the batteries I noticed one was not connected Hmmm!
Disconnecting the other two, after half an hour one was at 12.8v the other 12.3v so I reconnected only the one at 12.8v and all 'seems fine'.

The other oddity is that the MPPT unit has recored that the batteries went to absorption after 6h 45m fort only 1 min, then went to float.

NOTE: Battery electrolyte was ??? where. I noted the Victron was reading 2v lower than the batteries so it may have been charging an an extraornidarily high rate. Maybe the digital meter's battery ??
