The temperature limitation that matters, is the parasitic circuit element of cold-enhanced resistance inside the battery, not the chemical state of full/zero charge available. In short, battery charge isn''t lost if you cool it, because charge is conserved. A charge/discharge cycle, though, is intended to never apply to frozen batteries.
Lead-Acid Battery Specific Gravity. When a lead-acid battery is in a nearly discharged condition, the electrolyte is in its weakest state. Conversely, the electrolyte is at its strongest (or greatest density) when the battery is fully charged. The density of electrolyte related to the density of water is termed its specific gravity.

5 Lead Acid Batteries. 5.1 Introduction. Lead acid batteries are the most commonly used type of battery in photovoltaic systems. Although lead acid batteries have a low energy density, only moderate efficiency and high maintenance requirements, they also have a long lifetime and low costs compared to other battery types.
While standard lead-acid (flooded lead acid, or FLA for short) batteries self-discharge fairly rapidly, sometimes as much as 10% to 20% per month, the modern crop of lithium iron phosphate (lithium for short) batteries tend to self-discharge around 1% to 2% State of Charge (SoC) per month.

Sulfation can be removed from a lead-acid battery by applying an overcharge to a fully charged battery using a regulated current of around 200mA for a period of roughly 24 hours. This process can be repeated if necessary, but it is important to monitor the battery closely during the process to prevent overheating or damage.
The following are several steps you can take to protect your RV batteries while the RV is stored for the winter: Keep your batteries charged as a fully charged battery can withstand extreme subfreezing temperatures. Use a battery kill switch to keep parasitic loads from draining your batteries. Store your RV in a climate-controlled space.
