depends on what diesel engine you are running... but as a rule of thumb diesels do require higher amp batteries than equivalent petrol engines due to higher compression and the fact that the heaters* (Glow Plugs) and starter motor demand juice at the same time ...
*We call them heaters over here... my apologies

what about those ultra light batteries? i know gassers run them fine, but do they make any that can work well for a diesel?

A high amp battery is all your looking for...
Should be labled CCA then a number around the 500 - 1200 range
I wouldnt even *** on a battery less than 800 CCA

I've run 650CCA batteries during the winter in my diesel with no problems. If there is nothing wrong with your battery don't worry about it but if you are buying a new one get one with the highest CCAs that you can afford

even in north bay? must have been a pretty big 650CCA battery... i've lived in Timmins and it gets stupid cold there (only an hour away i think). i doubt a 650CCA batt would start a diesel there at -40C.
i have a 700CCA battery in my car right now.. its alright but has a little bit of a rough time starting the car at -10 and beyond. might also be normal tired engine syndrome though too...

do you mean the Glow plugs? Does burn use his block heater in -40?

I had a 10 year old VW dealer 650 CCA battery and the car was not plugged in at -40 and it started. I had to try 3 times before it started and stayed running. It had been sitting outside since it last ran for about 6 hours

the motor must have been in good shape then. my old jetta wouldn't even turn over at -32C a few years ago... what a PITA. (that battery was a 650CCA) of course it could have been bad connections to the starter i suppose...

Rotella T SB 0W40 and good battery/starter connections
The engine had 450k kms on it, it wasn't that good.

I would not go on cold CCA only. That is one of those numbers that can be fudges to suit what you want. How much you can draw from a battery at one time is not a good rating for a battery IMHO. You are limited by cable size anyway.
I have found that batteries are like many things, you get what you pay for. Stay far away from Canadian tire garbage. Get a good name brand (Interstate) and as big (physicaly) as you can get into the tray. You need lots of juice (Ah) when you have to crank it over for a long time with the glow plugs when it is -40.
I didn't see where you live but I think if it is warm all the time then there are no special needs for the diesel.

Cold cranking amps (CCA) is the amount of current a battery can provide at 0°F (−18°C). The rating is defined as the amperage a lead-acid battery at that temperature can deliver for 30 seconds and maintain at least 1.2 volts per cell (7.2 volts for a 12-volt battery). It is a more demanding test than those at higher temperatures.
I don't see how this can be fudged
