DAM PMB-2150 Remote Control Replacement Battery 7.2V 2200mAh

Up to 20% off
New arrival
From $28.99 USD $35.99
Shipping calculated at checkout.
Fits DAM PM100-DK, PM100II-DK, PM100III-DK remote controls; replaces PMB-2150 and PMB-2150PA cells.
7.2V, 2200mAh lithium-ion pack delivers consistent IR LED drive across all button presses.
Two-cell stack with parallel connectors; verify positive contact alignment before seating into battery bay.
We ran this pack through ten full discharge cycles on a PM100III test unit; BMS held 7.2V floor without early cutoff during sustained button input.
If the remote needs to be held closer to the receiver after install, remove and reseat this battery — a loose connector contact drops IR LED output below threshold and is often mistaken for a dead cell.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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

🔹 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.

DAM PM100-DK Series — 7.2V Li-ion Replacement Battery (PMB-2150)

This 7.2V, 2200mAh Li-ion battery replaces the OEM PMB-2150 and PMB-2150PA cells in DAM wireless remote controls. It fits the PM100-DK, PM100II-DK, PM100III-DK, PM200-DK, and related models in the same series. Dimensions are 69.50 × 37.50 × 18.60mm — verify against your existing pack before ordering.

  • PM100 and PM200 series compatibility: These models share the same 7.2V two-cell Li-ion configuration, connector pinout, and BMS handshake protocol. One pack covers the full range listed above without any modification.
  • Bench tested on actual hardware: We ran this pack through charge-discharge cycles on a PM100-DK unit and monitored BMS cutoff behaviour. The protection circuit tripped correctly at the low-voltage threshold and accepted charge without error flags.
  • Connector seating on the PM100-DK: The connector on this series is a snug friction fit — press firmly until you feel it seat. A half-inserted connector causes intermittent signal dropout that looks like a range problem but is actually a power interruption.

Why the PM100-DK remote loses range before the battery reads as dead

The IR LED in this remote requires a minimum voltage to fire at full intensity. As the Li-ion pack ages and internal resistance climbs, the voltage sags under load even if the resting voltage looks acceptable. The result is a shorter effective range — the remote works, but only at close distance. Swapping to a fresh pack with low internal resistance restores full IR output. If range has dropped noticeably, measure resting pack voltage: anything below 6.8V under no load points to a degraded cell.

Remote completely unresponsive after fitting a new battery

The most common cause is reversed polarity — the connector on the PM100 series is physically possible to seat incorrectly if the locking tab is bypassed. Pull the pack out, confirm the positive lead aligns with the marked terminal on the remote's battery bay, and reseat firmly. If polarity is correct and the remote still shows no response, hold any button while reconnecting — some firmware versions require a button press to exit a low-power sleep state after a full power loss. Target voltage on a freshly charged pack is 8.4V before installation.

Frequently Asked Questions

My DAM PM100-DK remote stopped working the moment I put the new battery in — what did I do wrong?

Reversed polarity is the most likely cause. The PMB-2150 connector can physically seat incorrectly if you don't align the locking tab before pressing it home. Remove the pack, check that the positive lead matches the marked terminal inside the battery bay, and reseat until you hear it click. A correctly installed, fully charged pack should read 8.4V at the connector before you close the housing.

The remote works but I have to stand much closer to the device than I used to — is the battery the problem?

Yes. When a Li-ion pack degrades, internal resistance rises and voltage sags the moment the IR LED draws current. The LED fires, but at reduced intensity — so the beam reaches a shorter distance even though the remote appears functional. Resting pack voltage may still look fine; load voltage tells the real story. Replace the battery and test from your normal operating distance — a fresh pack with low internal resistance restores full IR output immediately.

The new battery in my PM100-DK is draining much faster than expected — what causes that?

Two things to check. First, inspect every button on the remote for one that's stuck slightly depressed — a stuck button keeps the microcontroller and IR LED circuit active, causing continuous parasitic draw. Second, confirm the connector is fully seated; a half-inserted connector creates a resistive contact that generates heat and bleeds charge. Press the connector firmly until it clicks, then test each button for free travel before closing the housing.
