In the European Union advertising has to show Carbon dioxide (CO 2 )-emission and fuel consumption data in a clear way as described in the UK Statutory Instrument 2004 No 1661.  Since September 2005 a colour-coded "Green Rating" sticker has been available in the UK, which rates fuel economy by CO 2 emissions: A: <= 100 g/km, B: 100–120, C: 121–150, D: 151–165, E: 166–185, F: 186–225, and G: 226+. Depending on the type of fuel used, for gasoline A corresponds to about L/100 km (69 mpg ‑imp ; 57 mpg ‑US ) and G about L/100 km (30 mpg ‑imp ; 25 mpg ‑US ).  Ireland has a very similar label, but the ranges are slightly different, with A: <= 120 g/km, B: 121–140, C: 141–155, D: 156–170, E: 171–190, F: 191–225, and G: 226+. 
(k) Applicants for and holders of operating licenses are not required to requalify electric equipment important to safety in accordance with the provisions of this section if the Commission has previously required qualification of that equipment in accordance with "Guidelines for Evaluating Environmental Qualification of Class 1E Electrical Equipment in Operating Reactors," November 1979 (DOR Guidelines), or NUREG-0588 (For Comment version), "Interim Staff Position on Environmental Qualification of Safety-Related Electrical Equipment."
I have an RV setup of 2, 12V battery banks. The first consist of 2, 12V car batteries in parallel supplying a 1000w inverter. The second is 2 deep cycle marine 12V batteries in parallel supplying a 2000w inverter. I use two 100w solar panels to keep both banks charged. I recently purchased a Schumacher SE-1250 charger to start providing equalizer charges to the batteries. I have generated a tracker for measuring each cell temp and SG during the normal charging phase (10A) and for the EQ phase (30A). Each bank took about 12 hours to complete, 6 hours per battery. 5 hours at 10A and 1hour at 30A with readings every 30 mins for each cell. My plan is to do this quarterly to generate sufficient data to determine if I need to increase or decrease the EQ phase.
