|In extreme conditions, one of the most important things to have is a reliable power source. If you want to know what battery is best for your situation, you should first know how cold weather affects them. Off-grid living can become treacherous when the temperatures drop below freezing, and you want to know that you have your necessities covered. Lead-acid batteries tend to have a lower performance rate than their lithium counterpart. This makes lithium batteries a top power source for anyone wanting to explore places where the temperatures drop to frigid conditions. In this article, we look at how and why lithium batteries are the best option and also how our LT series batteries exceed normal cold weather expectations with superior technology.
Are 12v 100ah lithium ion deep cycle batteries good in cold weather?
LFP batteries are safe to use in temperatures ranging from -4 degrees Fahrenheit, up to 140 degrees Fahrenheit, which makes them practical for use in any weather conditions. Some off-grid solar, RV, and Camper Van owners live and venture into extremely cold conditions, making lithium batteries a great option for consistent, reliable power. Cold temperatures must be taken into account for any battery owner as they can be harmful to the well-being of a battery. With standard lead-acid batteries the cold can seriously degrade the health and longevity of the unit. Lithium batteries have much better performance at colder temperatures than lead-acid batteries. Typically, the more you pull from a lead-acid battery in cold temperatures the weaker it will become. LFP batteries warm up when you use them, lowering the battery’s resistance and increasing its voltage. When looking to upgrade or overcome your battery troubles, lithium is the clear winner when it comes to cold weather.
What Happens To Batteries In Cold Weather
We’re going to put it to you straight – lithium batteries fare far better in wintry conditions than other battery types, but even still you’re going to want to take care of them. With the right preventative measures, your batteries can survive and thrive this winter. To protect your batteries, let’s first look into why we need to protect them from harsh environments in the first place.
A battery’s job is to store and release energy. Cold weather can get in the way of these important functions. Just like it takes your body several minutes to warm up after being outside, the same is true for your battery. Cold temperatures increase the internal resistance of a battery. This can lower the battery’s capacity. AKA – the battery can’t release as much energy or retain a charge as well in cold temperatures.
You guessed it -this means you’ll need to charge those batteries more frequently during wintery weather. Another important thing to remember is that the lifespan of a battery-only includes so many charging cycles. This is something you want to preserve, not waste. Lithium deep cycle batteries are rated to last between 3,000 to 5,000 cycles. But lead-acid, on the other hand, typically last around 400 cycles, so you’ll want to use those cycles more sparingly.
How To Charge Lithium Batteries In Cold Weather
Charging in cold weather calls for a different protocol and is crucial when you want to make your investment last. Nearly every battery requires a more involved charging process when the temperature begins to drop. Lead-acid has a tighter range of suitable charging conditions when compared to lithium. Both, however, need to be within their temperature range and must be charged at a slower than normal rate.
The damage to the battery when charging at colder temperatures is proportional to the charging rate. Charging at a much slower rate can reduce the damage, but this is rarely a practical solution. When temps fall between 32 degrees and 14 degrees Fahrenheit, batteries cannot be charged at higher than .1C. When temps fall between 14 degrees and -4 degrees Fahrenheit, batteries cannot be charged at higher than .05C. These charging rates will definitely increase charging duration and complicate the entire process because you may not know how cold it could become during a charging cycle. In some situations, you could be going to sleep in 40-degree weather and waking up to a cold snap at 18 degrees Fahrenheit. If you were charging at a higher rate overnight, the falling temperatures could cause irreversible damage to your battery.
The number one rule when it comes to cold-weather charging is not to charge your batteries when the temperature falls below freezing without reducing the charge current. Unless you’re BMS communicates with your charger, and the charger has the ability to react to the data provided, this can be difficult to do. If you do charge below freezing temperatures, you must make sure the charge current is 5-10% of the capacity of the battery.
What is the best battery for cold weather?
BSLBATT cold weather lithium batteries are cold-weather performance batteries that can charge at temperatures down to -0 degrees Fahrenheit at a continuous rate, without the need for a reduced current. Most lithium-ion batteries will be permanently damaged when charging them in below-freezing temperatures. Without a Battery Management System (BMS) communicating to a charger that is programmed to reduce the current in those conditions, the only solution in the past was to have the battery at above freezing temperatures before attempting to charge it. This could either be by bringing them into a warmer environment or insulating them somehow by wrapping them in a thermal blanket.
The cold weather lithium batteries are specifically designed to excel in cold weather environments by heating the battery before commencing charge with a specialized heating element. The B-LFP12-100 LT is a 12V 100Ah lithium battery with the same size and performance as the popular RB100, but with additional cold-weather performance. This battery is the ideal choice for use in RVs, off-grid solar, electric vehicles, and in any application where charging in colder temperatures is necessary.
The cold weather lithium batteries offer a variety of models with lower and higher amp hours including B-LFP12-200 LT and B-LFP12-300 LT. The cold weather lithium batteries can be used in almost any cold-weather application and batteries should be chosen based on your capacity needs coupled with your space and weight requirements.
