Self-discharge
Self-discharge is a phenomenon in batteries. Self-discharge decreases the shelf life of batteries and causes them to have less than a full charge when actually put to use. How fast self-discharge in a battery occurs is dependent on the type of battery, state of charge, charging current, ambient temperature and other factors. Primary batteries are not designed for recharging between manufacturing and use, and thus to be practical they must have much lowe

What causes lithium battery self discharge?
The most common cause of lithium battery self discharge is moisture. The electrolyte solvent or water in the battery get dissolved by the moisture, creating an imbalance in the electrolyte of the battery. When this happens, an electric short will be created and a lithium ion leak will occur, causing a fire.
What happens if a lithium ion battery is not used?
When a lithium-ion battery is not in use, it will lose some of its charge. This is known as self-discharge and it’s a natural process that occurs with all batteries. Study shows that batteries happens to discharge even faster when the battery isn’t being used properly or stored in suboptimal conditions.
What is the self discharge rate of a lithium ion battery?
The self discharge rate of lithium ion battery, on the other hand, as low as about 3.5% over the same period. This means that if you're not using your battery regularly, you'll need to take into account the self discharge rate when planning how often to recharge it.
What is the mechanism behind self discharging lithium ion batteries?
Wikipedia says: Self-discharge is a phenomenon in batteries in which internal chemical reactions reduce the stored charge of the battery without any connection between the electrodes.
How to reduce battery self discharge?
There are a few things you can do to reduce battery self discharge: Store your batteries in a cool, dry place. Check the batteries regularly and recharge them if necessary. Use higher quality batteries, such as lithium-ion batteries that have the advantages of high energy density, low self-discharge rate, and long cycle life.
How fast does a lithium battery self-discharge?
The rate of self-discharge is also heavily dependent on temperature. The hotter a given battery is, the quicker it will self-discharge. Most lithium-ion batteries have a self-discharge rate of between 0.5-3% per month. This means that lithium battery will lose between 0.5 and 3% of its charge per month.
