Description
The Dogtra Battery BP74R3P is the 7.4V, 500mA lithium-polymer pack for the 2700T&B receiver and the 2300EXP. The 2700T&B collar runs a beeper as well as the e-collar, so a weak battery shows up fast on a long upland hunt. It’s a quick swap.
Will the Dogtra Battery BP74R3P fit my unit?
It fits the 2700T&B receiver and the 2300EXP. The 2700T&B remote uses the BP74TE3P. 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
Most owners notice it in the field first. The remote dies earlier than it used to, or the collar stops responding at the end of a long day. If the charger, contacts and cable all check out and the run time is still short, it’s the battery.
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. The BC10V Auto charger lists the 2700T&B and the 2300NCP.
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.
