Yes - I know about internal resistance and self-discharge.

Yes, caps loosened (although instructions on battery said not to.

Experience with cars has taught me that an eighth of an inch over the cels may be theoretically perfect it doesn't work in practice and the best way to charge is fill to about a quarter of an inch below the inside of the cap-thread-neck and charge immediately.

I've got an electrolyte tester somewhere but find them very ineffective. Best plan to hook up several old headlights, and put digital voltmeter on terminals and watch the fade. 4 big headlights nearly 20 amps should show what's what. Battery people use a thing like an electric fire with a voltmeter in.

Yes - it's on a modern charger so should get properly tapered up. I have got a 1920s trickle charger in the garage, but it needs me to take it to bits again and get at the switch in the overload cutout (based on a hot-wire galvanometer, a thing of beauty to some) to make it work, so the modern one will have to do. Interestingly, caravan and battery shops tell me my TP2 pack simply will not charge the battery fully because of insufficient voltage, so they must be lying.

Standard car alternator voltage = 13.8V - but to many connections between alternator and van battery so charging while towing ineffective in general...

Yes, that's why I discharged it and charged it again. The charger is saying "Ready Now" (that was Franki Valli wasn't it?) so I'll leave it overnight and then put in van to settle. I won't be ready with the amp and graphic for a day or so, although the basic speakers are in now. I think the easiest way to mount the radiocassette, graphic and amp will be to build them all onto a board in the garage and then bolt the board up to the underneath of the shelf, leaving a space next to it for the little LCDTV, and behind it for a sub in due course.

Fridge will be on its way to me tomorrow.

Snag - it appears the front window has not been secure (someone snapped the fire exit fastenings, before my ownership) and there has been some water ingress left hand front, and I am going to have to re-make the window catches, so this is also the time to go to an opening front window in case of heatwaves... It seems dry now but I will need to re-check, and if so the visible area of loosened trim will hardly show because of soft furnishings so I don't need to bother about trying to re-laminate the insulation board...

Hmm, now what else was on my list? Gas fire and brakes, I think....
