643 bobcat battery recomendation

[Shortbed70]

Have a 85 643 kubota 3 cyl deisel and I'm curious as to what cca battery would you recommend? Seems to crank pretty hard on a very cold day an after runnin the glow plugs there's not much battery left to crank with... This one is one month old but only 700 cca @32

Those engines required a lot of glow plug, pre-heat even when new. More battery you have the better (more reserve capacity). Keeping the battery warm using a battery blanket or trickle charger will increase the reserve capacity.
