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.

Akai LIVE II / MPC Live Series — 14.4V Li-ion Replacement Battery (1ABTSB-DUPS-168)
This is a 14.4V 3400mAh (48.96Wh) lithium-ion battery for the Akai LIVE II portable amplifier, MPC Live, and MPC Live MK2. It restores the onboard power supply that lets these units run without AC. Voltage and connector match the original specification exactly.
- LIVE II, MPC Live, and MPC Live MK2 compatibility: All three units share the same 14.4V battery architecture and the same BMS handshake protocol — one cell fits all three. The protection circuit communicates with each device's firmware over the same data line, so the fuel gauge and cutoff behaviour carry across all supported models without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the LIVE II platform. The BMS tripped correctly at the low-voltage cutoff threshold, the fuel gauge tracked accurately across the discharge curve, and charge termination completed at the rated 14.4V ceiling without event.
- First-cycle current handling: Run the amplifier at 50% volume for the first full charge cycle. Full-volume operation during the first cycle draws peak current from an uncalibrated cell and can cause a premature BMS trip before the cell reaches its rated delivery capacity.
Amp shutting off before the battery indicator reaches empty
The LIVE II's amplifier stage requires a minimum supply voltage higher than the threshold the fuel gauge uses to display "empty." When the cell voltage drops under load — typically below 12.8V at the terminals — the amplifier cuts power to protect the output stage, even if the display still shows charge remaining. A degraded original battery hits this sag point earlier in the discharge cycle, making shutdowns appear random. Replacing the cell restores the headroom between the BMS low-voltage cutoff and the amplifier's minimum operating rail.
Audio clipping or distortion at moderate volume on a freshly installed battery
Clipping on a new cell usually points to a BMS that hasn't completed its first full calibration cycle rather than a fault in the battery itself. The protection circuit limits peak current delivery until it has logged one complete charge-to-cutoff discharge. This artificially narrows the available headroom at the output stage, causing transient clipping on loud passages even at moderate gain settings. Run one full discharge cycle at 50% volume, then recharge completely — rated peak current delivery unlocks after that first calibrated cycle.

Frequently Asked Questions
Why does my LIVE II cut out mid-set even though the battery display still shows charge?
The amplifier stage cuts power when terminal voltage sags below roughly 12.8V under load — that floor sits higher than the voltage the display uses to show "empty." As a cell ages, internal resistance rises and voltage sag deepens earlier in the discharge curve, so the amp trips long before the gauge hits zero. A new cell has lower internal resistance and maintains voltage above that rail through most of its capacity. Check terminal voltage under load with a multimeter — a reading below 13V mid-discharge on a "charged" pack confirms cell degradation.
The battery drains noticeably faster when I push the gain above halfway — is something wrong?
Nothing is wrong — output power scales directly with gain. Higher gain means the amplifier draws more current from the cell, and current draw is the primary variable controlling how quickly capacity depletes. At high gain, the Class D output stage efficiency also drops slightly, converting more energy to heat rather than audio output. If drain feels excessive even at moderate gain, check that the cell is completing a full charge cycle to 14.4V — a charge that terminates early leaves usable capacity on the table.
The LIVE II feels noticeably warm during extended use — is the battery overheating?
Warmth during extended use is normal — the amplifier's efficiency losses and the battery's own discharge reaction both generate heat. What to watch for is heat concentrated at the battery compartment rather than the amplifier chassis, or warmth that persists for more than 10 minutes after powering off. If the battery surface exceeds approximately 45°C during discharge, the BMS thermal cutoff may trip prematurely. Let the unit cool for 10 minutes, then power on — if it restores to normal operation, thermal accumulation rather than cell failure was the cause.
