What is the effect of cold on Lithium iron phosphate battery?

Low temperature will slow down the chemical reactions that occur inside the battery, affecting its performance and reducing its discharge capacity. This means that at lower temperatures, the maximum energy released by the battery will decrease. All batteries are like this.

So, how does the LiFePO4 battery compare to the SLA option in cold environments? LiFePO4 batteries perform better than SLA batteries in cold conditions and have higher discharge capacity at low temperatures. At 0 ° F, lithium is discharged at 70% of its normal Nameplate capacity, while at the same temperature, SLA can only discharge at 45% of its capacity.

What is the temperature limit of Lithium iron phosphate battery?

All batteries are manufactured to operate within a specific temperature range. In terms of lithium, we will take our X2Power lithium battery as an example. The operating temperature range of these batteries is -4 ° F to 140 ° F. The temperature range of standard SLA batteries is 5 ° F to 140 ° F. Within this temperature range, the performance of lithium batteries is superior to that of SLA batteries.

What are some tips for LiFePO4 low-temperature charging?

Lithium iron phosphate battery does face a major disadvantage in cold weather; They cannot charge at freezing temperatures. Do not attempt to charge the Lithium iron phosphate battery if the temperature is below 32 degrees Fahrenheit. Doing so will lead to lithium plating, which will reduce the battery capacity and may cause short circuits, causing irreparable damage to the battery.

In order to charge the Lithium iron phosphate battery below freezing point, you need to raise its temperature first. The simplest way is to move the battery to a warmer environment. You can also try wrapping the battery with a thermal blanket or placing it near a small space heater.

What are the storage tips for LiFePO4 batteries?

When storing Lithium iron phosphate battery for a short time, please ensure that its charging state is 50% or higher. For longer periods of time (such as a complete season), you should fully charge the lithium battery to 100% before storage. You should also always store the Lithium iron phosphate battery indoors at room temperature.
