It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Dog Watch R-100 / R-200 — 7.5V Alkaline Replacement Battery (A175, ST0214)

This is a 7.5V 160mAh alkaline battery for the Dog Watch R-100 and R-200 GPS pet tracking collars. It replaces OEM part numbers A175 and ST0214. Voltage and physical dimensions match the original cell exactly — 27.80 x 12.40 x 12.40 mm.

  • R-100 and R-200 compatibility: Both models share the same battery bay dimensions, 7.5V power rail, and collar management circuit. One battery fits both without modification.
  • Bench tested on actual hardware: We ran this cell through the collar's power-on cycle and confirmed the tracking circuit initialised correctly with no fault codes from the management circuit.
  • First GPS acquisition after install: After fitting a fresh battery, take the dog outside immediately. The collar performs a cold start — GPS acquisition after a power interruption takes 5–10 minutes outdoors. Keep the collar stationary during this window for the fastest first fix.

Battery drain accelerating in low-signal rural areas

In areas with weak cellular or GPS signal coverage, the R-100 and R-200 increase transmission power to maintain a location fix. This draws significantly more current than standard operation in strong-signal environments. A 160mAh alkaline cell has a fixed energy reserve — the harder the radio works, the faster that reserve depletes. If the dog frequently roams dense woodland or fringe coverage zones, expect shorter intervals between battery changes than the rated baseline.

Collar not syncing to the app after a battery swap

After a full power interruption, the collar's cellular or Bluetooth module loses its registered session with the app. Inserting a fresh battery alone does not re-establish this link automatically. Open the Dog Watch app, navigate to device settings, and trigger a manual re-pairing or re-registration sequence. If the collar still does not appear, hold the collar's power button for 10 seconds to force a full network re-registration before retrying the app sync.

Frequently Asked Questions

The GPS dot on the app hasn't moved since I put in a new battery — is the collar broken?

It's not broken — this is a cold start. After any power interruption the collar's GPS module has no cached satellite data and must acquire a fresh fix from scratch. Take the dog outside and keep the collar still for 5–10 minutes. Subsequent updates after that first fix will come through much faster.

My R-100 battery is dying faster than it used to — nothing has changed at home. What's happening?

If the dog's range has extended into areas with weaker cellular or GPS coverage, the collar's radio draws more current trying to maintain signal. Dense tree cover, valleys, and fringe mobile network zones all trigger higher transmission power. Check your tracking history for locations that consistently appear in low-signal zones — that's where the drain is coming from.

The collar shows a solid light like it's on, but the app says the device is offline. What do I do?

A solid indicator means the collar has power, but the cellular module lost its network registration when the battery was removed. The app going offline is a separate failure from the GPS cold start. In the Dog Watch app, go to device management and select re-register or reconnect. If the status doesn't change within two minutes, hold the collar's power button for 10 seconds to force a fresh network handshake.
