About this replacement
Teleradio LE-TX-MX10 / LI-TX-MN6 / LI-TX-MD10 — 4.8V Ni-MH Replacement Battery (M241054)
This is a 4.8V 2000mAh Ni-MH replacement for the Teleradio M241054 battery pack. It fits the LE-TX-MX10, LI-TX-MN6, and LI-TX-MD10 wireless transmitters used to control overhead cranes and industrial hoisting equipment. Voltage and capacity match the original spec exactly.
- LE-TX-MX10, LI-TX-MN6, LI-TX-MD10 transmitters: These three remotes share the same 4.8V four-cell Ni-MH configuration, identical connector pinout, and the same charge termination logic — so one battery part number covers all three platforms.
- Bench tested on actual hardware: We cycled this battery through full charge and load discharge on a crane remote test rig. The pack held stable voltage under solenoid activation pulses and the protection circuit did not trip during repeated relay-engage sequences.
- Ni-MH idle storage care for infrequent crane use: Crane remotes can sit unused for weeks between lifts. Top-charge this battery once a month during idle periods — Ni-MH cells left at low state-of-charge for extended periods sulfate internally and lose capacity permanently.
Solenoid activation causing power dropout on a freshly installed battery
When a crane remote engages a solenoid or relay, it pulls a short inrush current spike — often two to three times the steady-state draw. A battery at storage voltage (around 4.6V for a 4.8V Ni-MH pack) has higher internal resistance and cannot supply that spike without a voltage dip. The transmitter interprets the dip as a low-battery condition and cuts out. The fix is straightforward: charge the battery fully before first use so internal resistance drops to its operational minimum and the pack can handle inrush without dropout.
Remote showing low-battery indicator immediately after swap
A new Ni-MH battery ships at storage voltage — typically 60–70% state of charge — not at full capacity. The LE-TX-MX10 transmitter reads voltage to estimate charge level, so a pack sitting at 4.6V triggers the low-battery flag straight away. This is not a fault with the battery. Connect it to the Teleradio charger and run a full charge cycle; once the pack reaches 4.8V under load the indicator will clear. Do not operate the remote on crane equipment until the charge cycle is complete.
