EcO Battery Replacement Kit

Your EcO V2 probe accompanies you season after season. If it stops sending data, the battery may simply be worn out. Rather than replacing everything, just replace what needs it.

Benefits

• Simplicity: guided installation, no special tools required
• Durability: extend the life of your probe rather than replacing it entirely
• Savings: only pay for what you need
• 2-year warranty on the complete probe

When should you consider a replacement battery?

Signs of a failing battery:

• The probe is no longer sending any readings — it is unresponsive, even when submerged in water
• You have reached the end of your previous battery's lifespan — the probe health check indicates it needs to be replaced

⚠️ Important note: Diagnosing a technical issue with an analyser can sometimes be tricky. Certain signs (such as unstable or inconsistent readings) may be linked to various factors (sensor wear, low battery, usage conditions…). The elements outlined above can help guide your analysis, but an accurate diagnosis may require more in-depth investigation. If in doubt, our customer support team is available to assist you and help identify the best solution for your situation. If uncertainty remains, opting for a complete replacement kit (battery + sensors) is the most reliable option to restore accurate readings and an optimal experience.

Our recommendation: the Complete Kit

If your probe is already a few years old, or if you're not certain the battery is the only source of the problem, we strongly recommend opting for the Sensors + Battery Kit. By replacing both at once, you can move forward with complete peace of mind for a long time — without the risk of a second order if the initial diagnosis was incomplete.
