In the realm of household tips, a common suggestion that often circulates is the idea of storing batteries in the freezer to extend their lifespan. Is there any truth to this claim, or is it just an old wives’ tale? Let’s delve into the science behind battery storage and explore whether freezing your batteries is a practical solution.
The science behind battery storage
The concept of freezing batteries traces back to the belief that colder temperatures slow down the chemical reactions within the cells, thereby preserving their energy capacity. While this idea holds some merit for certain types of batteries, it is not a universal solution and can even be detrimental to others.
Alkaline batteries: a freezer no-no
Alkaline batteries, the most common household batteries, do not benefit from freezing; in fact, storing them in your integrated fridge freezer from a retailer such as https://www.wellingtonshomeelectrical.co.uk/refrigeration/fridge-freezers/integrated-built-in.html may lead to performance issues. The electrolyte inside alkaline batteries can freeze at extremely low temperatures, causing the casing to expand and potentially rupture. This not only renders the battery useless but can also pose safety hazards.
NiMH batteries: cold tolerance to some extent
On the other hand, rechargeable nickel-metal hydride (NiMH) batteries can tolerate colder temperatures to some extent. Freezing NiMH batteries might slow down the self-discharge rate, preserving their charge for a more extended period; however, extreme cold can still cause issues, such as reduced performance and potential damage to the internal components.
Lithium-ion batteries: a strict no for freezing
For lithium-ion batteries commonly found in electronic devices, freezing is not recommended. These batteries have a more complex chemical composition and subjecting them to low temperatures can lead to irreversible damage. The electrolytes in lithium-ion batteries can form solid structures at freezing temperatures, disrupting the ion flow and diminishing the overall performance.
