Batteries come in many shapes, sizes, and applications, so it’s helpful to keep them in your home for when you need them. Proper battery storage will help prolong its life and avoid the risk of battery accidents, and make it easier to find them when you need them.
Steps
Battery Storage
Store when the battery is full to avoid sulphation that causes the battery to decrease in capacity.
Store when the battery is 30–50% full to ensure best performance. [2] X Research Source
If the battery cannot be charged for several months, it is recommended that you fully charge it before storing it. [3] X Research Sources[4] X Research Sources
Can be stored at any charge level. [5] X Research Sources
- Do not put batteries in the freezer unless recommended by the manufacturer. [8] X Research Sources
Traditional nickel-based batteries lose power very quickly even at low temperatures. They charge faster in cooler temperatures, but no less than 10°C for consumer grade chargers. [9] X Research Source
NiMH LSD (Low Self-Discharge) batteries are designed to maintain charge at room temperature.
- Do not store the battery in a metal case, use a sealed plastic container or a dedicated battery case.
- Do not store coins or other metal objects in the battery case.
- Arrange carefully so that the positive terminal of the battery does not come into contact with the negative terminal of another battery, otherwise cover the battery terminals with paper tape or plastic wrap.
Store rechargeable batteries
Fully charge every time the voltage drops below 2.07V/cell (12.42V for 12V batteries). [16] X Research Source
On average, recharge once every six months. [17] X Research Source
Fully charge up to 30–50% capacity every time the voltage drops below 2.5 V/cell. [18] X Research Source Do not recharge if voltage drops to 1.5V/cell. [19] X Research Source
Charge every few months on average.
Batteries are usually rechargeable, but their capacity will be permanently reduced. If the small lead acid battery is not rechargeable, charge it with low amperage with high voltage (~5V) for about two hours. [20] X Research Sources
Sulfate reduction equipment should not be used without experience. [21] X Research Source
The battery may enter a “sleep state” and not recharge. Use a battery charger that “jumps” the battery, taking care to charge it with the correct electrode.
Do not strike a battery whose voltage drops below 1.5V/cell for about a week or more because the battery is already permanently damaged and very dangerous to use. [22] X Research Source
Quite simply, some types only need to fully charge and discharge a few times to fully recover their capacity. [23] X Research Sources
If you want large-scale battery recovery, you may want to consider purchasing a battery analyzer that has a battery “recovery” function. [24] X Research Sources
Advice
- Remove batteries from electronic devices when infrequently used. Batteries in electronic devices will discharge faster when left alone.
Warning
- Wet batteries (water batteries) should not be stored for long periods of time. This type of battery requires regular maintenance to add water and prevent corrosion.
Things you need
- The battery
- Balloon bag (optional)
- Battery storage case (optional)
