Just found the temperature vs charging volage table in The Battery FAQ:

jgdarden.com/batteryfaq/carfaq9.htm#temp

So of the batt is about 10°C then you can add half a volt to the normal charge voltage, so up to 15.3V.

I'd always check the charge voltage with ~~an ammeter~~ a voltmeter in case the charger is a bit doolaly.

Trojan say "0.005 volt per cell for every 1°C below 25°C". So at 5C that's 20 x 0.005 x 6 = 0.6V. At 10C, 0.45V. Safe enough to add half a volt in winter.
