How to store batteries safely in self-storage units?


Considering the exponential growth of electronic devices being manufactured, batteries can be found and seen everywhere. By now, you may already know the numerous benefits of using self-storage facilities, and storing batteries are one of them, but there are some rules and words of advice on how to keep them safe. In case you are not familiar with the benefits of using self-storage units, check out our article on our top 5 good reasons to use self-storage.

In case you’ve already decided to rent a self storage container, the first thing that the company providing the storage unit must do is give you a list of items that you are not allowed to store. These include fireworks, cleaning products and items containing asbestos, but we have a whole article on what not to store in a storage unit and why, so make sure to give it a read. Whilst you may think that batteries are not hazardous, remember that they can easily leak, which can cause damage or even injuries under certain circumstances. With this in mind, we’ve put together a step-by-step guide on what is the best way to store batteries in self-storage units to give you a hand!

1. Take all the batteries out of your items 

Unless you’re using the self-storage unit for only a month or two, the best thing to do is take the batteries out of anything you want to store. If batteries sit for long periods without being used, this will likely drain them. 

In case there will be any leaks, the battery acid could damage all the equipment and items that are placed nearby. So, it is best to remove batteries before storing them and replacing them once you will be ready to put those items in use again. Also, remember that electronic equipment and accessories get outdated quickly, which means that time is not a battery’s best friend. Most batteries are made out of metal, which eventually corrodes, depending on how you store them. Also, single-use batteries can easily burst if they are left for long periods. All the “safe” batteries (or those that are considered safe), such as laptops and digital cameras batteries, are not very safe either. 

2. Keep them organised 

In case you have batteries out of their packaging, a good idea would be to keep them stored so all of the positive ends stay together. Avoid leaving them all over the place, in a box or bag, because if you do so, you could cause the positive and negative ends to rub against each other, draining the batteries, or causing a leak, or even an explosion, in the worst-case scenario. 

Similarly, avoid storing old and new batteries together, as this could cause either one or both batteries to leak. Dispose of the old batteries first, or store older ones in a different container than the one with the new batteries. Another pro tip is to avoid storing rechargeable batteries with alkaline ones, as if you do so, you could cause severe leakage or an explosion once again. In case you find batteries that can’t be used anymore, place them in a non-metallic container, whilst making sure that their terminals won’t touch, and then take them to a relevant depot at your local recycling facility, or simply leave them in a specially provided container so that they can get collected by the garbage man. 

3. Keep them away from your valuables 

Even if you take all the proper precautions, you still might end up with battery leakage, so consider where your valuables are being stored and make sure that you will keep all your batteries away from them.

We know that batteries are small and that people don’t think about how they are getting stored, but they can cause severe damage if ignored. The best way to keep batteries is to leave their original packing on, such as the plastic and cardboard wrap, as in that way, the batteries stay buffered and protected at all times. When dealing with rechargeable batteries, take into close consideration the level of charge left in them before storing them. In case the batteries are charged 100%, they will undoubtedly get wasted, and the idea is to know how to store batteries for longer life, not to ruin them! In case the battery is at 0% charge, it will most likely leak. Experts recommend that charging batteries to a level of 40% is the best choice, as rechargeable batteries discharge very slowly when stored away for long periods. 

4. Rent a climate-controlled self-storage unit 

When thinking about how to store batteries safely, you need to know that temperature is one thing you should be aware of. Storing batteries in heat can be very dangerous, especially in the warmer parts of the country. It is essential to know that even the smallest overheated battery can cause an explosion!

A suitable temperature range for storing batteries is between 4.5 and 21 degrees Celsius, while 15 degrees Celsius is considered ideal. Also, keeping batteries dry is very important to prevent corrosion and leakage, which means that the air around the batteries should not be too humid either. Ultimately, climate control means that you can maintain a relative humidity level of not more than 55%. But remember, most self-storage facilities don’t address the humidity aspect, so if you want to start storing batteries, the best thing to do is to rent a climate-controlled storage unit, which guarantees maximum humidity and low temperatures. 

To conclude, storing batteries in self-storage units is not generally recommended, however, it is not forbidden. This is simply because dangers exist, and the cost and inconvenience of alleviating those dangers can be more than it’s worth. This is especially true because people are often not thinking about the consequences of storing dangerous items in self-storage units, simply because they are either in the middle of moving houses, downsizing or perhaps facing some other sort of difficulties that occupy their minds most of the time. The best recommendation for you is to take your batteries at home, or throw them away, and buy new ones when you put your items in use again.
