Midland Albrecht TecTalk Float 3.7V Replacement Battery 2000mAh

Midland Albrecht TecTalk Float — 3.7V Li-Polymer Replacement Battery

This is a 3.7V, 2000mAh Li-Polymer battery for the Albrecht TecTalk Float handheld two-way radio. It slots directly into the TecTalk Float body and restores transmit and receive capability when the original cell has degraded. Voltage and capacity match the factory spec exactly.

• TecTalk Float platform fit: The TecTalk Float runs a 3.7V single-cell Li-Polymer architecture. This pack matches that voltage rail and the physical cell footprint — 47 × 40 × 10.1mm — so the radio's BMS accepts the handshake without triggering a fault state on power-up.
• Bench tested on actual hardware: We cycled this pack through full charge and load discharge on the bench. The BMS held cutoff correctly at both ends — no undervoltage lockout during discharge and no overcharge condition at top of charge. Transmit current spikes on PTT did not trip the protection circuit.
• First insertion on the TecTalk Float dock: New Li-Polymer cells ship at storage voltage, typically around 3.6–3.75V. If the dock shows a fault indicator on first insertion, remove the pack, wipe the contact pads with a dry cloth, and reseat firmly. The dock requires a clean contact cycle to register the pack before charge current begins.

TecTalk Float cutting out mid-transmission on a new battery

The TecTalk Float draws a current spike the moment PTT is pressed — transmit load is significantly higher than standby draw. If the pack's BMS trips during that spike, the radio cuts mid-word and may restart. This happens when cell impedance is elevated, either from a deeply discharged new cell or a degraded old one. On a new pack, run one full charge cycle before heavy PTT use — this lets the cell reach its rated impedance and the BMS handle transmit surges without tripping. A healthy cell at full charge should hold above 3.5V under transmit load.

Bar indicator showing one fewer bar than expected after fitting this pack

The TecTalk Float uses voltage-threshold steps to drive its bar indicator — it reads pack voltage and maps it to bars, nothing more. A new cell at storage voltage sits lower than a freshly charged cell, so the radio displays fewer bars even though the pack is not faulty. Charge the pack fully before reading the indicator. After a complete charge cycle the voltage will sit at approximately 4.2V and the bar display will reflect that correctly.
