LiFePO4 battery is one of the most popular batteries at present. Whether it is an energy storage system or an electric vehicle, it can be seen almost everywhere. Of course, this is a result of its good security and relatively good performance. But don’t forget that the LiFePO4 battery is also an electrical appliance to some extent, and proper LiFePO4 battery maintenance can make it go further.
What to do with daily LiFePO4 Battery Maintenance?
Unlike some lead-acid batteries, LiFePO4 batteries do not need to be added with water and liquid, and LiFePO4 batteries do not need to be added with water and liquid during a long life, and they do not need to be drained. This is the maintenance-free design that many people love. That’s why we usually don’t need to deal with the battery itself too much. Let it charge, let it discharge, that’s fine.
In normal maintenance, we will pay more attention to the part of the battery terminal (including studs & washers & busbars), because this part is the main part of the battery for power transmission. Once there is a problem with this part, it will undoubtedly affect the output and input performance of the battery.
The most common situations we usually encounter are stains, oxidation and loosening of battery terminal parts. The easiest way to deal with loosening is to re-tighten it, and the easy way to deal with stains is to use a sponge to clean it up.
A little more troublesome is the oxidation treatment. Busbars are generally made of copper or aluminum, because these two materials have good electrical conductivity. The oxidation treatment is generally to buy a deoxidizer, and then use a soft brush to wipe repeatedly until all the oxides fall off. But if you don’t have a deoxidizer at home, vinegar and lemon are also good substitutes.
It should be noted that when cleaning, pay attention to disconnect the load of the LiFePO4 battery, and then wear insulating gloves to operate to prevent any possibility of accidents.
In addition to the part of the battery terminal, we also need to pay attention to the LiFePO4 battery compression. Some improper operations may cause the battery to bulge during use, which means that the compression of the battery is not perfect. What we need to do is to increase the compression force several times until the battery returns to its original condition. It should be noted that we cannot deal with excessive LiFePO4 battery swelling. The solution to this situation is to carry out battery recycling and purchase new batteries. Batteries with serious swells have major safety hazards and are highly not recommended for continued use.
What to avoid in LiFePO4 Battery for Long-term Conditions?
- The environment is too high or too low temperature. Although LiFePO4 batteries are resistant to high temperature and help to weaken self-discharge at a certain low temperature, excessive high temperature and excessive low temperature are not beneficial to LiFePO4 batteries. See the LiFePO4 Temperature Rangefor details.
- Store in an environment with high humidity. An environment with high humidity can more easily lead to oxidation of the battery terminals and, in some cases, increase the risk of leakage. So it is best to store LiFePO4 batteries in a ventilated and dry environment.
- Long-term storage. LiFePO4 batteries are a kind of lithium-ion batteries, and regular and complete charge-discharge cycles are very important for LiFePO4 batteries. Long-term storage without use can easily lead to a permanent decline in the performance of the battery. Generally speaking, it is recommended that a complete charge-discharge cycle be required for a maximum of half a year. For proper storage of LiFePO4 batteries, see LiFePO4 Battery Storage.
- Stack the LiFePO4 batteries randomly. This includes stray wires and other metal objects, which undoubtedly increases the risk of accidents. such as short circuit.
- Excessive battery usage. For example, overcharge and over-discharge, both of which will undoubtedly seriously damage the LiFePO4 battery, and are irreversible damage, which will eventually lead to a decline in battery performance.
Although everything seems cumbersome, the LiFePO4 battery is still very worry-free as long as you pay attention to them. Regular LiFePO4 battery maintenance can make the batteries more durable, and from another point of view, our lives can also become more convenient.
