I was wondering what Trojan had to say about shelf life.

1. What is the shelf life of my battery?
The limiting factor of battery’s shelf life is the rate of self-discharge which itself is temperature dependent. VRLA batteries will self-discharge less than 3% per month at 77º F (25º C). Flooded batteries will self-discharge up to 15% per month at 77º F (25º C). VRLA batteries should not be stored for more than 6 months at 77º F (25º C) without recharged. The specific gravity or voltage of flooded batteries should be monitored every 4 – 6 weeks and should be given a boost charge when they are at 70% stat of charge (SOC). When batteries are taken out of long storage, it is recommended to recharge before use.

Your mileage may vary.
The good news is the self discharge decreases with ambient temperature and not many places have been 77 degrees this winter.
The bad news is low SC & low temps team up on battery discharge.
