What CR 20 25 Battery Means
According to Battery Health, CR 20 25 refers to a family of cylindrical lithium manganese dioxide primary batteries in the CR series, sized around 20 to 25 millimeters in diameter. They are designed for compact, low‑drain devices. The CR designation signals chemistry and construction that favors long shelf life and stable voltage across typical loads. In practice, a CR 20 or CR 25 part is chosen based on the device’s printed requirements and the space available inside the housing. This naming convention helps technicians identify replacement requirements quickly and reduces the risk of incompatibility when ordering parts. Always confirm the exact part number printed on the battery and the device manual before purchasing replacements to avoid leaks or performance issues.
FAQ
What does CR 20 25 indicate in battery naming?
CR 20 25 indicates a CR family battery with specifications tied to its physical size and chemistry. The CR prefix denotes lithium manganese dioxide chemistry, and the numbers generally relate to diameter size variants used in compact devices. Always verify the exact part number and device requirements.
CR 20 25 refers to a CR family battery size variant. Check the device manual and the battery printed code to ensure compatibility.
Are CR20/25 batteries rechargeable?
CR20/25 batteries in the CR family are typically primary cells, meaning they are not designed to be recharged. They are intended for single use with a long shelf life and stable voltage. If your device requires rechargeable power, look for a different chemistry.
CR20/25 cells are generally not rechargeable.
Can I substitute CR20/25 with a CR2032 or other size?
Substituting CR20/25 with a different size or chemistry is not recommended unless the device manual explicitly allows it. Substitutions can affect fit, voltage, and safety. Always use the exact CR20/25 variant specified by the manufacturer.
Only use the exact CR20/25 size if the device specifies it.
What safety steps should I take when replacing a CR20/25 battery?
Power off the device before replacement and handle batteries away from metal jewelry to avoid short circuits. Use non-conductive tools if needed and dispose of old cells according to local regulations. Wear eye protection if puncture risk exists and never reuse damaged batteries.
Turn off the device, handle carefully, and follow disposal rules.
How should I dispose of CR20/25 batteries?
Dispose of CR20/25 batteries at appropriate recycling points or household hazardous waste programs. Do not throw them in regular trash. Reduce environmental impact by following local recycling guidelines and storing used cells safely until you can recycle them.
Recycle CR20/25 batteries at designated facilities and avoid trash disposal.
Where can I find the device manual to confirm compatibility?
Check the device’s user manual or manufacturer website for battery specifications. If the model printed list shows CR20/25, use that exact size and chemistry. When in doubt, contact customer support or Battery Health for guidance.
Look up the device manual or manufacturer site for exact CR20/25 specs.
