Battery Care Tips
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
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.

Digital Ally DVM-RMT / DVM 500 — 3.6V Ni-MH Replacement Battery (CS2/3F6 3S1P)
This is a 3.6V, 600mAh Ni-MH replacement battery for the Digital Ally DVM-RMT wireless remote and DVM 500 system. It fits the remote control unit used to trigger recording on Digital Ally body and dash camera setups. OEM part numbers CS2/3F6 3S1P and 135-0035 both cross-reference to this cell.
- DVM-RMT and DVM 500 remote compatibility: Both remotes share the same 3.6V three-cell Ni-MH pack configuration with identical connector and physical footprint, which is why one replacement cell covers both units.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the DVM-RMT remote and confirmed the BMS accepted the cell without fault codes or cutoff events at normal remote operating loads.
- Ni-MH conditioning on first install: Ni-MH cells in low-draw remotes can show inaccurate charge indicators if installed partially charged. Run one full charge cycle in the OEM charger before using the remote in the field — this lets the charge circuit calibrate to the new cell's capacity curve.
Why the DVM-RMT remote stops responding before the battery reads empty
Ni-MH cells have a relatively flat discharge curve, which means the remote's voltage-threshold indicator can read mid-charge right up until the cell drops below the radio transmission floor. The remote's RF transmitter draws a short high-current burst each time you press a button — at end of cell life, that burst pulls the voltage below the minimum the transmitter needs, and the signal never reaches the camera. The cell is not truly dead, but it cannot sustain the transmission pulse. Replace or recharge the cell when button presses become intermittent, even if the indicator still shows charge remaining.
Remote charges but camera body stops acknowledging button presses after storage
Ni-MH cells self-discharge at roughly 1–3% per day at room temperature. A remote left unused for several weeks can drop to a state low enough that the first few charge cycles do not fully recover capacity. This is not a fault with the replacement cell — it is a known Ni-MH behaviour after deep self-discharge. Charge the battery fully, then run it down through normal remote use before charging again. After two to three full cycles, the cell reaches its rated 600mAh and button response to the camera system returns to normal.

Frequently Asked Questions
The DVM-RMT remote is fully charged but the camera ignores button presses — what's causing it?
The RF transmitter in the remote pulls a short current spike on every button press. If the Ni-MH cell has degraded or hasn't been cycled yet, that spike drops the cell voltage below the transmitter's operating floor and the signal never fires. Charge the battery fully, then press and hold the power button on the remote for five seconds to force a hard reset of the transmitter circuit. If the camera still does not respond, run one full discharge-and-charge cycle — a fresh Ni-MH cell sometimes needs a cycle before it can sustain the transmission burst.
The battery percentage on the remote jumps around erratically after installing this replacement — is the cell faulty?
It is not faulty. Ni-MH cells have a flatter discharge curve than the original cell may have had after years of use, so the remote's voltage-threshold indicator maps the new curve differently at first. The readings stabilise after two or three full charge-discharge cycles as the indicator logic adjusts to the replacement cell's actual voltage steps. Run the remote down to low charge through normal use, charge it fully, and repeat — erratic readings typically resolve by the third cycle.
The replacement battery drains noticeably faster in cold weather during outdoor recording shifts — is that normal for this cell?
Yes. Ni-MH chemistry loses usable capacity in cold conditions — at around 0°C, a 600mAh cell can deliver noticeably less charge than at room temperature because internal resistance rises and the electrochemical reaction slows. Keep the remote in an inside jacket pocket between uses to hold the cell near body temperature. Capacity returns to normal once the cell warms back up, so cold-weather drain is not permanent degradation.
