How do I store my lithium battery? A question we receive from our customers on a daily basis, especially in the Winter season. The answer depends on the temperature you are storing the batteries in and the period of time. Here’s a summary of how to store your LiFePO4 battery:

Recommended storage temperature: -5 to +35°C (23 to 95 °F)

Storage up to 1 month: -20 to +60°C (4 to 140 °F)

Storage up to 3 month: -10 to +35°C (14 to 95 °F)

Extended storage time: +15 to +35°C (59 to 95 °F)

It is highly recommended to store lithium batteries indoors during the off-season. It is also recommended to store LiFePO4 batteries at about a 50% state of charge (SOC) or higher. If batteries are stored for long periods of time, cycle the batteries at least once every 6 months. Do not store batteries that are discharged.

DISCONNECT BEFORE STORING LIFEPO4

Many customers have main switches to disconnect the power to the batteries. We recommend that you take the extra step to ensure the batteries are TRULY disconnected. This is because many RVs would still have components running in the background, such as the C02 sensor, backlit stereo, or some other emergency sensor that may be bypassing the main disconnect switch. The best thing to do when you’re storing the batteries is to physically disconnect the main positive and negative wires from the lithium batteries. This will ensure that during storage time, the battery is not being discharged and that you have plenty of charge in the LiFePO4 batteries when you use them again. Make sure you always use a lithium charger and not one meant for other battery chemistries.

LiFePO4 batteries have a low self-discharge rate of 2% a month. This means that when a lithium battery is stored, it’ll lose 2% of its charge capacity every month. In order to prevent a higher rate of discharge, we recommend disconnecting all power draw from your batteries. When you store LiFePO4 batteries, it is important that you store them with a state of charge (SOC) of 50% or higher. A higher state of charge is recommended when storing for an extended period of time. If you want the battery to retain a good level of charge after the storage period is over, you should charge them to 100% and store them in that fully charged state.
