Can I Use a CR2032 Instead of a 2025 in My Key Fob?
If you’ve ever asked yourself, can I use a 2032 battery instead of a 2025 in my key fob, you’re not alone. This is one of the most common questions when replacing button cell batteries. The good news? In most cases, yes, you can — and we’ll explain why.
Let’s unpack the differences between CR2032 and CR2025, when it’s safe to swap them, and where to find the best-value replacements in New Zealand, including our 10-pack CR2032 battery for just NZ$4.49 at eMax.co.nz.
CR2032 vs CR2025: What’s the Difference?
So, what's the difference between Energizer 2032 and 2025? It comes down to thickness. Both are 20mm in diameter and 3V in voltage, but:
- CR2032 is 3.2mm thick
- CR2025 is 2.5mm thick
The 2032 has more internal volume, meaning more lithium, and therefore typically offers longer battery life. So when people ask, can I use CR2032 instead of 2025 — the answer is usually yes, as long as your device can accommodate the slightly thicker size.
Can I Use a 2032 Battery in My Key Fob?
Can I use 2032 instead of 2025 in a key fob? Most car key fobs and garage remotes can handle a 2032 battery in place of a 2025. However, make sure the battery compartment isn’t too tight. If there’s just a little wiggle room, a 2032 will often fit snugly and provide longer-lasting power.
Can I use a different battery in my key fob? Only if the voltage and diameter match — and you’re confident it fits. Swapping to different sizes or lower voltages can cause malfunctions. That’s why CR2032 remains one of the most reliable, compatible, and widely used replacements available.
Is an Energizer 2032 the Same as a CR2032?
Yes. Is an Energizer 2032 the same as a CR2032? Energizer 2032 is a branded version of the standard CR2032 specification. It follows the same 3V lithium coin-cell design and will work the same in any device that calls for a CR2032. This also applies to Duracell, Panasonic, and other brands. However, you don’t need to pay top dollar for the name — and that’s where value options from trusted NZ suppliers shine.
Which Battery Can Replace a CR2032?
Looking for alternatives? You might wonder, which battery can replace a CR2032 or what can I use instead of a CR2032. While CR2032 is widely compatible and preferred, other 3V lithium coin cells with the same diameter can sometimes work — like CR2025, if thickness isn’t a critical factor.
However, the safest move is to stick with CR2032 whenever possible — especially when you can buy a 10-pack of CR2032 batteries for only NZ$4.49 online at Emax.co.nz. With widespread compatibility for watches, remotes, calculators, and car keys, you’ll always have spares ready.
