💡 Why does a twelve volt lead acid pack lose capacity faster during winter storage seasons?
Tracking those subtle voltage drops makes monitoring slow drain handy for dodging trailering headaches down south.
- Internal resistance rises when temperatures drop below freezing reducing available cranking amps for heavy marine starters.
- Sulfation builds on plate surfaces if resting voltages stay under twelve point four volts permanently shortening useful lifespan.
- Modern chargers cycle on and off frequently causing shallow charges that leave active material inactive until fully rebalanced.
