Subject: Re: Battery advice for LG45
Hi David,
I haven't forgotten, still getting round to taking photos.
Meanwhile, a little more research. Firstly, your Z4166 number will almost certainly be the Lagonda factory part number. Most of their part numbers for my V12 are Pxxxx, but a smattering are Zxxx, eg the wheels are Z4101/2.
Have at last come across a 1939 Lucas catalogue online. This frustratingly details many cars, but not Lagonda, for most items. Perhaps there's a separate section at the end I haven't got to yet! Nevertheless, struck gold with "Batteries". This states that 1935 (and on, going by their style) 4 1/2 litre : 2-6TXR13. For 1938 LG6 and V12, 2-SLTR15E ... thus it differs slightly from the 2 units SLTSR15E detailed in the handbook. Needless to say, it can't even be that "simple". My works record states (Lagonda part number P8017) 6LTSR15!
The 6TXR13 is also noted as fitted to 1931: all models, 1932: Supercharged, 1933: 2 and 3-Litre. The only other vehicle using a 6TXR13 is the Hispano Suiza 30hp; interestingly, the 37.2hp has a 12TXR13. Raises an interesting point as to the meaning of these references. 6 and 12 are obvious, but some, like those for my V12 have neither stated. I'd take a guess that the other number featured is the number of plates. The letters? Conjecture S = Short, L = Long, T = Tall, X = Extra, R = Regular, W = Wide. But then there are Ys and Ds.
I think I've found an answer re the voltage absence for the V12 & LG6 reference. They are Lucas Lucas batteries; the 6TXR13 is a Lucas CAV battery! This also disproves my theory (already!). Two grades of battery are tabled; the basic version of the 6TXR13 is 6TXW13. The listings are headed (basic) "WOOD SEPARATORS", whilst the 6TXR13 is under "DELUXE MODELS WITH THREADED RUBBER INSULATION". Thus, W = Wood, and R = Rubber. Cor, this reminds me of algebra!
The 6TXR13 specifcation is: Actual capacity in amp hours when discharged in 10 hours; 75amps, and in 20 hours, 85 amps. Length 8 1/2", Length over lugs 9 3/8" (in other words, that will presumably be the original spacing for your mounting studs), Width 6 7/8", and Height over terminals 9 1/2". Regarding that latter, note that the height with cover isn't stated, probably because the cover was an extra, 5/6d!
Unfortunately for me, not so easy for my V12 batteries, there is no reference close enough, but perhaps I can figure something out. I can see that the only other cars fitted with 2-SLTR15E were Alvis SP25s and 4.3s.
