![]() ![]() Both CR2025 and CR2032 are non-rechargeable batteries. Non-rechargeable– Since both batteries follow lithium-manganese dioxide technology, they are counted as rechargeable batteries. Since the first two digits of CR2025 and CR2032 batteries are ‘20’, we can infer that their diameter is 20mm. ![]() Hence both batteries are round coin cells.ĭiameter– As per IEC, the first two digits stand for the diameter. Shape– The second letter in their name, ‘R’ denotes that the shape of the batteries is round. The similarity in performance of these batteries is due to the fact that both of them use the same chemistry. According to IEC, C stands for lithium manganese dioxide chemistry. From the previous articles, we are aware that the battery names follow the nomenclature as per the 60086-3 standard of the International Electrotechnical Commission (IEC). Similarities between CR2025 and CR2032Ĭhemistry– CR2025 and CR2032 are similar in their names itself. This is also the reason you should never use batteries with different capacities in series. Similarly, replacing all cells except the one that has some juice left may cause the whole battery pack to appear dead. And since all are connected in series, there is no current flow. So, the new CR2032 is able to supply the current to the device but the other cells cannot. This also creates a huge difference in voltage between the new one and the old one. Reason? The capacity of this new cell is much higher than the used-up cells(not fully depleted) connected in series. The whole battery pack will appear dead, maybe not instantly but very soon. For example, suppose you placed a new CR2032 or CR2025. You should never in any circumstance replace a single cell. As explained above, using the CR032 pack will last longer than the CR2025 pack. Replacing all cells will cause no problems. Replace the depleted CR2032 with a new CR2025.Replace the depleted CR2032 with a new CR2032.Replace all the batteries with new ones, either CR2032 or CR2025.But with time one of the batteries may run out of energy and you will have to replace it. If all the batteries are identical i.e, have the same capacity or Ah rating and C-rating, there is no issue. Some projects require multiple cells in series(for higher voltage). Replacing CR2032 with CR2025, as far as the weight is concerned, will make the device lightweight which is a good thing. So unless you have a project or application where weight is a constraint, CR2025 can be replaced with CR2032. CR2032 weighs 3 g whereas the weight of CR2025 is 2.6 g. Weightĭue to the difference in thickness, their weights are slightly different. Note: More capacity means CR2032 will run longer than CR2025 for the same application. If capacity is not your concern simply replace CR2032 with CR2025 without a second thought. So, if you have an application where you can’t compromise the battery’s running life, use CR2032 only. CR2032 capacity is 235 mAh whereas CR2025 is rated at 170 mAh max. The capacity of CR2032 is slightly more than that of CR2025. So no mechanical adjustment is required in this case. Note: CR2032 will fit perfectly in the battery holder for CR2025. Take an aluminum foil, fold it and place it over CR2025 in order to fill that extra space of 0.7 mm. That’s why you will have to make a slight adjustment in the battery holder if you want to use CR2025 in place of CR2032. CR2032 is 20 mm wide and 3.2 mm in height whereas CR2025 is 20 mm wide and 2.5 mm in height. Dimensions of CR2032 and CR2025 are different! Though they have similar diameters, their thickness is not the same.
