The Risky Business of Battery Substitution
2. Consequences of the Swap
So, what actually happens if you decide to be a battery rebel and use a CR2032 instead of a CR2025? The most common outcome is simply that the battery compartment wont close properly. The extra thickness of the CR2032 can prevent the device from sealing, leaving a gap. That might seem minor, but it can expose the internal components to dust, moisture, and other nasties that could lead to damage.
However, in some cases, you might be able to force the compartment closed. Don't! Applying excessive pressure can damage the battery contacts or even the device itself. You could bend the contacts, making it difficult for any battery to make a proper connection in the future. Or, worse, you could crack the casing of your device. Is saving a trip to the store really worth that risk?
But let's say, against all odds, you do manage to shoehorn that CR2032 in and the device seems to work. Is everything suddenly sunshine and rainbows? Not necessarily. The improper fit can lead to inconsistent power delivery. This could manifest as erratic behavior, like your car key fob only working intermittently, or your digital scale giving you fluctuating readings. It's like trying to run a marathon with a pebble in your shoe — doable, but not exactly optimal.
There's also a small chance, though less likely, of damaging the battery itself. A compressed battery can potentially leak or, in very rare cases, even rupture. Battery leakage is a nightmare, as the corrosive chemicals can damage your device and pose a hazard to you. While the probability is low, it's still a risk you should avoid.
