Description
The Dogtra Battery BP37X370 is the 3.7V, 370mA lithium-polymer battery for the 280X receiver. If the collar used to last several days between charges and now barely makes it through one session, this is the fix.
Will the Dogtra Battery BP37X370 fit my unit?
It’s made for the 280X receiver (the collar). The 280X remote uses the BP37X850. 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
Short run time is the main sign. Others include the unit turning off mid-session, a charge that won’t hold overnight, or a battery that looks swollen when you open the case. A swollen pack should come out straight away and shouldn’t be charged again.
Fitting the new battery
It’s a small job. Power down, open the case, swap the plug-in battery and close it back up, keeping the waterproof gasket clean and in place. Don’t overtighten the screws. Charge it all the way before you take it out. If you’d like to see it done first, the manual for your model on Dogtra’s website shows the steps.
Charging and care
Treat it like your phone battery: charge it when it’s convenient, don’t let it sit dead for long, and keep it out of extreme heat. Store it part-charged in the off-season and it’ll last noticeably longer. It charges over USB-C, and the 5V2500 dual USB-C charger covers the 280X.
Keeping a spare
If the unit is something you depend on, buy two. Fit one now and keep the other in a dry bag for the day the first one runs low far from a plug. It’s a cheap bit of insurance.
Why genuine matters
We only sell genuine Dogtra batteries. They’re the same size, voltage and plug as the pack that came in your unit, so there’s no guessing about fit, and the compartment closes properly over them. That matters on a waterproof unit, where a cover that doesn’t sit flat can let water in.
Dogtra Battery BP37X370 questions
Does the Dogtra Battery BP37X370 fit the 280X 2-dog collars?
The 2-dog 280X uses 280X receivers, so you’d need one battery per collar.
Will it affect the LED or tone?
No. Those features just stop working when the battery is flat, so a new pack brings everything back.
Does it come charged?
It may have some charge from the factory, but give it a full charge before you rely on it.
