Description
The CAT+ Super Photocell 260 mAh Rechargeable Battery is the only rechargeable battery officially recommended by Thames Medical for use with CAT and CAT+ Doppler blood pressure monitors.
Designed specifically for veterinary use, this Soshine 9 V Li-ion battery provides a consistently high voltage under load, something that many standard or supermarket batteries can’t achieve. Stable power ensures your Doppler maintains a clear, strong signal and accurate readings, even during lengthy anaesthetic or monitoring sessions.
While many generic 9V batteries drop below the 7.6 V minimum operating threshold, the CAT+ Super Photocell battery maintains dependable performance for up to 7 hours of continuous use. It’s rechargeable, environmentally friendly, and typically lasts 1–2 years in regular practice use, offering excellent long-term value.
Why choose the CAT+ Super Photocell battery?
- Consistent voltage – avoids signal dropouts or “low battery” warnings
- Reliable performance – proven in Thames Medical testing for CAT+ Dopplers
- Long battery life – up to 7 hours per charge, 1–2 years lifespan
- Eco-friendly – rechargeable, reducing waste and replacement costs
- Fully compatible – approved for CAT and CAT+ Dopplers
For best results, keep the battery on charge when not in use and use the recommended CAT+ battery charger to maintain cell health.
Why not all batteries are equal
Through years of testing, Thames Medical has found that only a few batteries perform reliably in veterinary Dopplers. Many generic 9V options, even well-known brands, fail to sustain the voltage required for consistent Doppler sound and sensitivity.

For Veterinary Professionals
Accurate, repeatable blood pressure readings depend on stable power delivery. A poor-quality battery can cause inconsistent Doppler tones, erratic readings, or power loss during a procedure. The CAT+ Super Photocell battery is proven to reduce these issues, keeping your monitoring equipment performing at its best when your patients need it most.
