This blog covers lead acid battery charging at low temperatures. A later blog will deal with lithium batteries. Charging lead acid batteries in cold (and indeed hot) weather needs special consideration, primarily due to the fact a higher charge voltage is required at low temperatures and a lower voltage at high temperatures.
Failure mechanisms may be different but they are just as damaging as those created by higher temperatures. Operating lead-acid batteries at low temperatures, without temperature compensation will have damaging consequences for both the application and the battery. These are principally:
However, a well charged lead acid battery in good condition will not freeze in practical use. But the less charged it is, the more susceptible to freeze damage. Even for a fully charged lead acid battery, there’s still a point of freezing. But those temperatures are extremely cold and you likely will not ever experience that cold (keep reading).
Without getting into the complexities, suffice to say maintain the battery in a fully charged state, as at low states of charge the electrolyte is more water like and freezes earlier than in a fully charged state. Lead acid batteries come in a variety of types:
Heat is the worst enemy of batteries, including lead acid. Adding temperature compensation on a lead acid charger to adjust for temperature variations is said to prolong battery life by up to 15 percent. The recommended compensation is a 3mV drop per cell for every degree Celsius rise in temperature.
Damaging a lead acid battery can be very dangerous for you and your rig and should be avoided. Our mission is to educate people on the benefits of lithium batteries and how they can add value to your experience in a boat, an RV or off grid solar system.
Older battery technologies, such as lead acid and NiCd, have higher charging tolerances than newer systems, such as Li-ion. This allows them to charge below freezing at a reduced charge C-rate. When it comes to cold-charging NiCd is …
How To Recover A 0V Lead Acid Battery. One of the most common reasons a lead acid battery shows 0V is sulfation. This happens because, inside a lead acid battery, …
The batteries show increased charge acceptance, improved cycle life and the power output without further application of external treatment during cycling at sub-zero temperatures.
Six test cells, two lead–acid batteries (LABs), and four lithium iron phosphate (LFP) batteries have been tested regarding their capacity at various temperatures (25 °C, 0 …
