Cold temps can affect a battery, voltage doesn't matter -6V or 12V. What condition is the battery in? I don't mean how new, or if it was recently 'charged'. I mean, is it a good reliable brand, not some cheap wally world cloned wanna-be? New cheap ones can be junk before you get out the door. The power source, the battery, is the single most important component in any electrical system. Invest in a good, reliable brand like DEKA, INTERSTATE, EXIDE, or DURACELL. Then invest in a good float charger, NOT any trickle charger -there is a difference. Many of us use the Battery Tender brand. Keep it on the battery when tractor is idle for weeks on end. The thing that depletes battery life the quickest is the constant discharging and recharging. You can put your charger on a battery for a week and if it has a dead cell and/or fails to sustain a full charge, won't do any good. Have your trusty local starter/alternator shop bench test the battery. Poor/incorrect wiring is usually the major cause of non-starting issues. Start here: battery test, wiring verification, spark test, and distributor tune-up.

You need a good battery to:
1. Spin the starter
2. Engage the Starter Motor Bendix
3. Provide voltage to the coil.
As the battery gets weaker, the first thing to fail is your spark.
The more current you use to spin the starter, the less you have for the ignition.
