Asskea DC20 Replacement Battery 12V 2100mAh Ni-MH

Up to 19% off
New arrival
From $96.99 USD $119.99
Shipping calculated at checkout.
Fits Asskea DC20, DC30, PRO I medical suction devices; replaces OEM part 110651-O battery.
12V, 2100mAh Ni-MH chemistry delivers sustained power for portable clinical equipment operation.
Connector seats directly into DC20 housing slot with positive and negative terminals flush-aligned.
We bench-tested this cell on Asskea charge dock; BMS accepted load after one full cycle.
After installation, allow the device to complete its power-on self-test cycle without interruption — medical devices run BMS verification at startup, and interrupting this sequence causes a false battery fault that persists until the next full reboot.

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.

Asskea DC20 / PRO I Secretion Suction Apparatus — 12V Ni-MH Replacement Battery (110651-O)

This is a 12V, 2100mAh Ni-MH replacement battery for the Asskea DC20 and related secretion suction devices. It fits the DC20, DC30, PRO I, and additional secretion suction apparatus models that share the same OEM part number 110651-O. Voltage and capacity match the original specification exactly.

  • DC20, DC30, and PRO I platform compatibility: These models share the same 12V battery rail, connector format, and BMS handshake protocol. A single cell chemistry and form factor covers all of them — the BMS on each device reads cell voltage and communicates state-of-charge the same way.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on the DC20 platform. The BMS completed its learn cycle after the first full charge-discharge pass, and the charge indicator advanced normally through subsequent cycles.
  • Post-installation self-test protocol: After fitting this battery, allow the device to complete its full power-on self-test without interruption. The DC20's BMS runs a startup verification sequence — cutting power during this window registers a false battery fault that persists until the next clean reboot.

Self-test failure after battery swap on the DC20

The DC20 runs a BMS learn cycle at first power-on with a new cell. If the device hasn't completed one full charge-discharge cycle, the internal cell model doesn't match the actual capacity curve of the new Ni-MH cell. This mismatch trips the self-test and the device logs a battery fault. Run one full charge-discharge cycle before clinical use — after that cycle, the BMS recalibrates and self-test passes cleanly.

Charge indicator stalls below 100% on the first charge

On the first charge cycle, the DC20's charge IC applies a conservative current limit to an uncharacterised new cell. This is intentional — the controller won't push full charge rate until it has measured the cell's internal resistance. The indicator may stall at 80–90% for an extended period before completing. Do not interrupt the charge. Let it run to termination, then discharge fully and recharge — the second cycle reaches 100% at normal rate.

Frequently Asked Questions

My DC20 is alarming low battery right after I confirmed it charged fully — what's happening?

The DC20's BMS uses a voltage threshold calibrated to a characterised OEM cell. A new Ni-MH cell hasn't completed its first learn cycle, so the BMS reads a slightly lower resting voltage and triggers the alarm even at full charge. Run one complete charge-discharge-recharge cycle without interruption. After that cycle, the BMS recalibrates and the alarm clears — resting voltage on a cycled Ni-MH cell at 12V should sit around 13.2V fully charged.

The DC20 won't power on at all after the replacement battery sat unused for several months — is the cell dead?

Ni-MH cells self-discharge faster than other chemistries — after several months in storage, voltage can drop below the DC20's BMS recovery threshold, typically around 10V per 12V pack. The BMS interprets this as a damaged cell and blocks power-on as a protection measure. Connect the charger and leave it on charge for a full uninterrupted cycle — the charge IC will trickle-charge the cell back above the recovery threshold before switching to full rate. If voltage recovers above 10.5V, the BMS releases the lockout and the device boots normally.

The DC20 is shutting off unexpectedly during use, but the battery shows charged — is this a BMS trip?

New Ni-MH cells deliver lower peak current in the first 5–10 cycles because the electrode surface hasn't fully activated. The DC20's suction motor pulls a sharp load spike at startup, and if the cell can't hold voltage above the BMS cutoff threshold during that spike, the device shuts off as a protection event. This is not a fault in the battery — it resolves after the cell completes its break-in cycles. Run 10 full charge-discharge cycles under normal device use before drawing conclusions about cell performance.
