What happens if a battery goes bad in winter?
In extreme cases, such as temperatures below 0°F (-18°C), some batteries can lose up to half their capacity. By following these steps, you can ensure optimal battery performance and longevity throughout the winter season. Charge your batteries one final time to ensure a full recharge and reduce the risk of freezing.
How do I choose a battery for cold weather?
Select batteries with suitable cold-weather operating and charging capabilities. Be cautious about sizing battery banks based on 80% Depth of Discharge (DoD) in cold conditions, as decreased capacity may lead to insufficient power reserves. For broad maintenance tips and instructions, check out our Safety First Guide.
What should I do before storing my leisure battery?
Before storing your leisure battery for the winter, it's essential to perform a thorough inspection to identify any issues that may need attention.
