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.

Brother IntelliFax-1960c / 2580c — 3.6V Ni-MH Replacement Battery (BCL-BT10)
This is a 3.6V, 700mAh Ni-MH replacement battery for the Brother IntelliFax-1960c, IntelliFax-2580c, BCL-D10, BCL-D20, and compatible portable fax models. It slots directly into devices that take the BCL-BT10, BCL-BT20, LT0197001, or BCL-BT part numbers. It restores cordless operation and memory backup when the original cell degrades.
- IntelliFax-1960c and 2580c compatibility: Both models share the same 3.6V single-cell Ni-MH format, connector pinout, and BMS communication protocol — one battery fits the full range without modification.
- Bench tested on actual hardware: We cycled this battery through full charge and discharge on the IntelliFax platform. The BMS accepted the cell without fault codes, and charge termination triggered correctly at full capacity.
- Pre-session charging for portable fax use: Charge the battery fully before starting a fax session. Portable fax machines spike current demand during the scanner warm-up and modem handshake phases simultaneously. A partially depleted cell can drop below the modem's minimum voltage threshold mid-handshake and abort the transmission before a single page clears.
Why the IntelliFax cuts out during modem handshake on battery power
The IntelliFax-1960c draws current from three subsystems at once during transmission: the scanner, the thermal print head, and the modem. Ni-MH cells have a measurable internal resistance that rises as the cell ages or cools. When all three loads fire simultaneously, voltage at the cell terminals can sag below 3.2V — the modem's minimum stable operating point. The machine reads this as a line fault and drops the call. A fresh cell with low internal resistance sustains voltage above that threshold through the full handshake cycle.
Battery showing full charge but dying before transmission completes
This is a capacity fade symptom, not a charging fault. Aged Ni-MH cells lose active material over time and report a full charge state while holding only a fraction of their original 700mAh. The battery indicator reads high because the BMS measures voltage, not true stored energy. Under the combined load of scanning and modem operation, the actual charge depletes quickly and voltage collapses. Replace the cell and verify the new battery charges to the full 3.6V nominal before the next session.

Frequently Asked Questions
My Brother IntelliFax-1960c won't start a fax transmission when running on battery — what's causing it?
The modem handshake requires a stable voltage above 3.2V at the cell terminals. If the battery is partially depleted or the cell has aged, internal resistance causes voltage to sag the moment the scanner and modem load up together, and the machine drops the attempt before the call connects. This isn't a phone line issue — it's a battery voltage floor problem. Charge the battery to full and retest; if the fault repeats immediately, the cell has aged past useful capacity and needs replacing.
The fax starts transmitting fine but cuts out halfway through a multi-page document — is that a battery issue?
Yes — this is a different failure from not starting at all. The modem can establish the initial handshake on a partially charged cell, but sustaining the connection through multiple pages keeps the scanner, modem, and thermal head running continuously. That combined draw depletes the remaining charge faster than the BMS anticipates, and voltage drops mid-transmission. A full charge before each session reduces the risk; if it still cuts out on a fully charged battery, the cell's capacity has degraded and 700mAh is no longer being delivered.
The IntelliFax battery drains noticeably faster than it used to even on short sessions — what's happening?
Ni-MH cells undergo capacity fade through shallow cycling — repeatedly charging before the cell fully discharges trains the battery to report full at a lower actual charge level. The scanner and thermal printer together pull more current than most people expect from a fax device, so even a modest capacity loss becomes obvious quickly. Run the battery down until the low-battery warning appears, then charge it fully in one uninterrupted session to partially recondition the cycle range. If capacity doesn't recover after two full discharge-charge cycles, replace the cell.
