Have you got a battery warmer? That really helps. Battery capacity drops with temperature, as does its ability to take a charge. I spliced mine in with the block heater cable, so there's only one plug to connect.
Because the battery is warm, it will deliver more current when you start. Once the engine is running, the battery will also take a charge better, because it's still warm. I think that will also help the battery to last longer.
Plus, check your electrolyte level. It should be over the top of the plates. If it's low, add a bit of distilled water.
If Princess Auto were a real girl, I'd ask her to marry me.
