Description
The Dogtra Battery BP37P2400 is the big one: 3.7V and 2400mA, made for the Pathfinder series. GPS units work harder than a standard e-collar receiver because they’re constantly calculating position, so a healthy battery matters more here than almost anywhere else.
Will the Dogtra Battery BP37P2400 fit my unit?
It’s listed for the Pathfinder series. The smaller Pathfinder Mini receiver uses the BP37P1300 instead, so check which collar you’ve got. Check the model name on the back of your remote or on the receiver label before you order. If it’s worn off, send us a photo and we’ll tell you which battery you need.
Signs it’s time for a new battery
Batteries don’t usually fail all at once. You’ll notice the unit needs charging every day instead of every few days, then it starts switching off in the cold, then the low-battery warning comes on soon after you’ve unplugged it. Once you’re seeing those signs, a new pack is the cheapest fix.
Fitting the new battery
Switch the unit off and open the battery compartment, which on most models means removing a few small screws. Unplug the old pack, holding the plug and not the wires. Fit the new one, tuck the wires so they won’t get pinched, and check the seal is seated before tightening the screws evenly. Give it a full charge before the first session. The owner’s manual for your model, on Dogtra’s website, shows where the battery sits.
Charging and care
Li-Po packs like this one don’t have a memory, so you can top them up whenever you like. What hurts them is heat and being left flat for a long time. Don’t leave the unit charging on a hot dashboard, and give it a charge every few months if it’s in storage. For charging, the BC5VAUTO 5 volt charger covers Pathfinder TRX and Pathfinder2 units.
Keeping a spare
A spare is worth thinking about if you hunt for several days at a time or run more than one dog. It costs a lot less than a lost day in the field. Label it with the date you bought it so you know which pack is older.
Why genuine matters
Everything we sell is original Dogtra stock, brand-new. An exact match means the cover closes flat, the gasket seals, and the charger reads the battery correctly. Those are the three things that tend to go wrong with packs that only roughly fit.
Dogtra Battery BP37P2400 questions
Why does my Pathfinder die faster in winter?
Lithium batteries give less in the cold. A worn Dogtra Battery BP37P2400 makes that much worse, which is often when people first notice they need a new one.
Will a new battery fix a GPS that loses signal?
Not usually. Signal problems are more often about the antenna or terrain. A new battery fixes short run time and random shutdowns.
What if I order the wrong battery?
Unused parts in their original packaging can go back within 30 days. Details are on our shipping and returns page. Better still, ask us before ordering and we’ll check the fit.
