I’ve recently discovered that many people store batteries in their refrigerator, presumably because some well intentioned science teacher taught them colder temperatures slow down the rate of energy discharge. While the science behind the idea has merit, most battery manufacturers recommend against storing your batteries in the fridge for numerous reasons related to safety. So if you shouldn’t keep your batteries next to the mayonnaise, where should they be stored?
If you’re taking the time to invest in solar energy, a solar panel battery is a great way to store excess energy and use it at a later time. Though it’s possible to install solar for your home or RV without a battery, foregoing the use of a battery will make it so that you might have to connect to the power grid more often, spending more money on energy than you need to.
When you do invest in off-grid solar batteries or any other type of solar battery, solar panel battery maintenance is critical. When stored properly and cared for correctly, your solar batteries will last longer, store energy better, and ensure you’re getting the right bang for your buck. We’ll break down everything you need to know about storing and caring for lithium batteries. Lithium batteries are used for many things, and they are very safe. But proper use, handling and storage are important for keeping workers safe on the job.
How to Store Lithium Batteries
Lithium Ion batteries, like this 48v lithium ion battery 400ah, require a bit of extra care when it comes to storage techniques. These are often the most sought-after batteries for solar battery charging because they are rechargeable, but they can be expensive, so storing them properly is in the best interest in terms of cost and longevity. Below are the top factors to consider when storing lithium-ion batteries:
Battery Charge
Before disconnecting your battery from the system that it supports, charge it between 30% and 50% charged. You don’t want to fully charge it before placing the battery in storage, but you should charge it every 3-6 months so that it doesn’t lose too much of its charge over time. When you are ready to use the battery again, take it out of storage and charge it fully prior to use.
Storage Area
You wouldn’t store dried food in cold, wet conditions, right? In the same way that food can spoil if not stored properly, your lithium battery can be ruined if you store it improperly. Keep it in an open, dry area that gets air regularly and stays within a temperature range of -13°F to 149°F.
Battery Handling
Lithium-ion batteries are powerful, but they are also fragile. When you are moving or handling the battery, do so with care. The last thing you want to do is drop it on a hard surface, bump it against a sharp corner, or put large amounts of pressure on the battery casing.
Temperature
As mentioned above, keeping your Renogy battery within the recommended temperature range is critical. Make sure it stays out of extreme sunlight or heated areas that could reach temperatures higher than 149°F. Batteries are often stored in garages or outdoor shops but depending on the weather in your area and the ventilation offered by your space, that could lead to a disaster for your battery.
Exposure to Elements
Being hit with direct sunlight, rained on, or even subject to high amounts of humidity and moisture can cause corrosion and damage to your battery. Battery storage is an integral part of solar panel battery maintenance, so don’t overlook it.
How to Store Lithium-ion Batteries: Maintenance and Handling Precautions
Monitor battery charge status while charging
Ensure temperature controls are set to specified temperatures
Observe run time with a fully-charged battery
If you drop a battery, inspect closely for damage and isolate that battery if possible until fully tested
Check batteries before placing them in storage for irregularities in charge status
Avoid exposing Li-Ion batteries to excessive vibration
Do not keep batteries in excessively high OR low temperatures
Always handle batteries with caution
Place batteries in storage after the building reaches recommended temperature levels
Do not use damaged batteries
In case of contact with fluid, do not rub your eyes. Immediately flush eyes at an eyewash station
Wash hands after handling batteries
Battery Maintenance Tips for Lithium-Ion Batteries
With proper lithium-ion battery care, your batteries will last longer, charge faster, and perform better. When you’re using batteries to help power your house, RV, or other devices, you want each battery at peak performance always, and your battery maintenance will have a major impact on that. For the care of lithium batteries, the following items should be a regular part of your solar panel battery maintenance routine:
Cleaning
Lithium-ion batteries are more resilient than other types of batteries such as lead batteries, but you should still keep them clean to enjoy the best results. Be sure to disconnect your battery before conducting any cleaning steps. Once disconnected, take a damp cloth or soft brush to clean the top of the battery and terminal, removing any dust or debris. If needed, you can use a gentle household cleaner to remove difficult dirt or grime. Then, use a clean cloth to dry your battery and ensure it is completely dry before placing back in storage or connecting it to a charging source.
Review & Inspection
If you stick your battery away and never look at it, you could uncover an unwelcome surprise down the line. Be sure to check in on your battery and conduct regular inspections no matter what season it is. Look at the top of the battery and its terminals to ensure that it is clean and clear of corrosion or damage. Also, take a few minutes to examine the cables and connections; if needed, replace damaged cables with new ones.
Voltage & Charge Checks
You want your battery to stay within a healthy level of charge, so be sure to regularly check its levels to see if it is discharging too quickly. In terms of voltage, if your battery cannot be activated with a current greater than 1A or if it is activated with a voltage below 10V, something is wrong. Do not use the battery until the situation is fixed.
Conclusion
Lithium batteries are, by and large, a safe and reliable source of portable energy. The number of incidents involving lithium batteries is relatively small, and the general likelihood of being injured by lithium batteries is also low. However, an ounce of prevention is worth a pound of cure, as the saying goes. Knowing a little about the types of lithium batteries, their potential hazards, and safe handling and storage of lithium batteries will go a long way toward ensuring your safety and the safety of your coworkers, employees, or even your family.For details, please refer to:48v lithium ion battery pack
