Quick Answer
For most Sepura STP9000, SC20, SC2020, and STP8000 radios, a compatible 7.4V 1880mAh lithium-polymer battery like the CELLONIC replacement is a reliable choice. Confirm your model and battery part number before ordering.
Why Battery Compatibility Matters
Sepura radios are built for professional use, and the battery is a critical component. Using an incompatible battery can lead to poor performance, shorter talk time, or even damage to the radio. Always check your radio model and the original battery part number (e.g., 300-00631, 300-00634, 300-00635) before purchasing a replacement.
The CELLONIC replacement battery is designed to work with a wide range of Sepura models, including the STP9000, STP8000, SC20, SC2020, SC21, and STP9038. This broad compatibility makes it a convenient option if you have multiple radios in your fleet.
Capacity and Voltage: What to Look For
The voltage and capacity of a replacement battery must match the original specifications. For Sepura radios, a 7.4V battery with 1880mAh capacity is a common standard. The mAh rating indicates how long the battery will last on a full charge; higher mAh generally means longer talk time, but it must be compatible with the radio's charging system.
The CELLONIC replacement offers 1880mAh, which is designed to meet the original specifications. This ensures you get the expected performance without overloading the radio.
Decision Rules for Choosing a Sepura Battery
- Check your radio model: Verify that your radio model is listed as compatible. The CELLONIC battery supports STP9000, STP8000, SC20, SC2020, SC21, STP9038, and more.
- Match the original battery part number: Look at the label on your current battery. If it shows 300-00631, 300-00634, or 300-00635, the CELLONIC replacement is a direct match. If your part number is not listed, contact the seller to confirm compatibility.
- Verify voltage and capacity: Ensure the replacement is 7.4V and has a capacity that meets your usage needs. The 1880mAh rating is standard for these models. For heavy use, consider carrying a spare battery to avoid downtime.
