HMB PORTABLE - Guidelines

To store a portable battery to last longer, you should follow these general guidelines:

Store the battery in a cool, dry place, away from direct sunlight and heat sources. High temperatures can cause the battery to degrade more quickly.
Store the battery at a moderate charge level, ideally between 50% and 75%. Avoid storing the battery in a fully charged or fully depleted state, as this can also cause the battery to degrade more quickly.
Avoid storing the battery in a discharged state for prolonged periods of time. If you're planning to store the battery for an extended period, charge it up to around 50-60% before storing it.
Keep the battery clean and dry. Wipe the terminals with a clean, dry cloth to remove any dirt or corrosion.
Avoid storing the battery in extreme temperatures. If the temperature is too low, the battery's capacity will be reduced and if the temperature is too high, the battery will degrade more quickly.
If possible, store the battery in a battery case or bag to protect it from damage.

By following these general guidelines, you can help ensure that your portable battery maintains its capacity and performance for as long as possible.

To deal with a waterlogged portable battery, follow these steps:

Immediately remove the battery from the device in use.
Clean the battery with a dry cloth or tissue to remove the air that is outside.
Let the battery dry for several days in a warm, dry place. Do not use a hair dryer or other heat source to dry the battery, as this may cause damage.
Once the battery is completely dry, try plugging it back into the device and turning it on to see if it still works properly.
If the battery still does not work, it is best to contact the manufacturer or supplier for more or replace it with a new one.

Remember that water can damage electronic components, so always be careful and respond quickly when water gets in.
