Lead Acid Batteries
Lead Acid Batteries
(OP)
Is there a way to protect lead acid batteries from harsh winter conditions, we always have battery failures after winter due to the freezing conditions & it is becoming quite expensive. Is there an additive or something to help this situation?

Barring that:
> Park indoors
> Cover with the vehicle insulation - marginal, given the 12 hrs or so it'll probably be parked
> Cover the battery with insulation

RE: Lead Acid Batteries
If you are then I will let you in on a little secret that goes against normal thinking!
The best way to store a battery for the winter is to to put it in your deep freeze.
You have to make shure it is charged up and dry first.
Batteries left idle in a warm place will soon start to collect sulfates on their plates which will soon render the battery useless.
This is a chemical reaction of the sulfuric acid electrolite in the battery.
In short any and every chemical reaction known to man speeds up with heat.
My boat batteries live in the freezer all winter and my snowmobile batteries live there all summer and I havent lost one yet!

Up in the morning, car starts just fine, windshield not frozen and nice and toasty in the front seat while I warmed up the engine --- usually just a few minutes if I timed the snowplow just right. If I missed, it would idle for longer while I shoveled my way out of the drive. Hated that snowplow!

As the batteries discharge while sitting idle their freezing point rises and they are more likely to be damaged. The solar cell and charger were about the price of one battery but I don't know if the company tried it or not because I don't work there anymore.
A good number of their battery replacements were due to arcing and subsequent melting of the terminals from continually being unhooked because there were very few installed (and not bypassed) lock out switches.
As far as automotive applications, batteries last 3-5 years up here in freezing cold Canadian winters... because they don't sit idle very long and are fully charged when it gets cold.

I will take note of what has been suggested.
