Replacement Battery for Sportdog TEK Handheld

This CameronSino DS-CS-SD815SL battery replaces the SAC54-13815 pack in Sportdog TEK V1L, TEK-H and TEK-V1LT handheld transmitters. It is a 3.7 V lithium-polymer cell rated at 1.9 Ah. The pack is supplied new and black. It is built for owners who need a direct drop-in power source for those specific training collars.

Thermals Noise and Power Draw

Lithium-polymer chemistry keeps self-discharge low and the cell runs cool during the intermittent transmit cycles typical of dog-training use. No fan or active cooling is involved, so operation is silent. The 7.03 Wh capacity supports normal training sessions without excessive heat buildup. The pack is not suited for continuous high-drain applications beyond the transmitter design.

What the OEM Compatibility Means

The 100 % OEM-compatible claim means the connector, voltage and dimensions of 49.10 x 29.30 x 13.20 mm match the original SAC54-13815 pack exactly. No wiring adapters or firmware updates are required. Installers simply swap the old cell for this one. The battery does not add charging circuitry, waterproofing or runtime beyond the original specification.

Questions about this item

How do I install the DS-CS-SD815SL battery into my Sportdog TEK V1L transmitter, and what step is often missed?

Open the transmitter's battery compartment, align the 49.10 x 29.30 x 13.20 mm Li-Polymer pack with the contacts matching the SAC54-13815 orientation, then secure the cover fully so the seal stays watertight.

What maintenance or replacement will this 1.9 Ah Li-Polymer pack need over time?

Expect gradual capacity fade after several hundred charge cycles; replace the pack when runtime drops below your field needs, using only a 3.7 V 1900 mAh Li-Polymer cell of the same 49.10 x 29.30 x 13.20 mm footprint.

What limit appears first during a long training day with continuous transmission?

The 7.03 Wh energy capacity sets the hard ceiling; sustained high-power RF output will drain the 1900 mAh cell faster than standby use, so plan for a swap or recharge once the voltage drops below the transmitter's cut-off threshold.
