one battery is bigger and one battery is smaller. You also need to check what battery you need before you buy some and if you have some spare use them.
The above answer is utter rubbish, I'm afraid.
"2032" means 20mm diameter, and 3.2mm thick
I don't know the correct answer, but suspect they're simply different manufacturers' designations.
CR2032 batteries are a small flat battery that is used in a variety of devices. Blood sugar monitors, watches, and calculators all require the CR2032 battery. The average lifespan of one of these batteries is one year; however, they have been known to run up to five years. The lifespan largely depends on the amount of usage required by the unit. Of all the watch batteries, the CR2032 is arguably the most common.
one of the worlds greatest mysteries
CR2025 = Diameter: 20 mm. Thickness: 2.5 mm. Capacity: 160 mAh, CR2032 = Diameter: 20 mm. Thickness: 3.2 mm. Capacity: 220 mAh
A lithium battery cr2032 battery does not really cost that much. You should be able to find these batteries in the store for $3 or $4 tops.
No, these types of batteries are not technically able to be recharged.
Nope. I am no battery expert, but I have, in my hot little hand, one CR2025 and one CR2032. The two have the same diameter and both are 3 volts, but the CR2032 has a considerable amount of extra depth. My camera remote requires a CR2025. I have some extra CR2032's laying around for a scale, so I thought I would give it a shot. The CR2032 does not fit.

Yes you can. However, the 2025 is 0.5mm thinner so will be a slack fit. It is also down on capacity; a lowly 165mAh as opposed to the meaty 220mAh of the 2032. The real difference is that on a constant 15Kohm load drawing 190uA @ 200C, the CR2032 will last 1000 hours and the CR2025 800 hours.
A CR2032 lithium battery is a small button sized battery often used in PC's, calculators and watches. It is not possible to recharge this kind of battery. They are designed only to be used and then replaced with a new battery.
Yes you can, as long as there is wiggle room inside the device. The CR2032 is slightly thicker. However, mixing batteries is dangerous, so be careful using the device until you know how it will react to the alternative power.
No. You would only have half the voltage required as they are the same voltage.
Most calculators use 1.5 volts from small button-cell batteries, such as LR44 or CR2032.
