Can You Store Batteries or Other Electronics in a Storage Unit?

Self Storage Tips

As technology and electronic manufacturing increase, so do batteries. Especially in regards to cars, our tech is relying on battery power more than ever. Self-storage comes in handy for most things, but with batteries, does it have the same effect? Here we’ll break down some answers to that question and lend some advice on battery storage.

Over Time Batteries Lose Power
Because self-storage units hold items for months on end to years on end, it’s worth it to consider that you may take them out from time to time. Electronic equipment has a quick life cycle, so newer gear may be bought in the course of living. If this happens, you can replace it with what’s currently inside. It’s easy to forget what you’ve left in there.

Over time, batteries disintegrate and get depleted. Time is not on their side. The metal of the battery disintegrates over time, and if stored incorrectly can increase the speed of corrosion. Single-use batteries can burst over a period of time if left unused, and integrated batteries that you find in laptops and cameras can also degrade.

Where To Store Batteries
When storing batteries, remember to take out the battery if it’s in a device. Keep them at home, or a safe and separate place in the storage unit. You can discuss with a storage company like M.I. to figure out the best place to put them. You can also keep batteries where they came from if they have not been used, or you could place them in a plastic box specifically designed to carry batteries. Keep one type of battery separate from a different type and don’t leave them in the equipment where they came from.

If you won’t be needing your batteries for the foreseeable future, then recycle them appropriately. Don’t just toss them in the trash. Before you throw them out, place them in a non-metallic container, making sure their terminals are separated and not touching (tape over the ends helps with this). Then do a quick Google search to find out what your community does for digital recycling. Maybe you could leave them in a special container for the garbage collector or take them to a recycle depot.

Maintaining Battery Life
If you choose to park your battery-powered vehicle or regular vehicle in self-storage, it’s important to regularly recharge the battery. Remove it entirely to charge it. If your unit comes with an electrical outlet, you can charge it with a ‘tender’, also known as a ‘trickle charger.’ If you’re unable to do this, charge the battery at home. If you choose to leave the battery inside the vehicle, just disconnect the negative cable, and reconnect it when you visit. Make sure to run the car so you can fill up the charge completely.

Temperature Is Crucial
Temperature is crucial when storing batteries in a storage unit. In the warmer areas of the country, this can be very difficult. In our storage units in Newton, North Carolina, we have climate-controlled units for these months if so desired. Keep in mind that even though you may not consider storing in the summer months, or leaving it there for years, batteries could potentially explode. Especially in the summer months. An ideal climate of 40-70°F with 60°F being the best is what to aim for. Climate-controlled self-storage lockers could also hold batteries at around 55-85°F, but these temps are typically meant for special books or wine.

Keeping batteries away from moist and wet areas is vital to preventing damage, leakage, and corrosion. The air should be dry and not too humid. Climate control works well in these situations because they maintain an atmosphere of a maximum of 55% humidity. Temperature-controlled storage facilities exist as well but avoid the humidity issue altogether. We recommend purchasing a climate-controlled unit for storing batteries to control the humidity levels and keep them cool, very far from explosions.
