Palfinger 590 Crane Remote Ni-MH Replacement Battery 7.2V

Palfinger 590 / 960 / EEA2512 / 790 Series — 7.2V Ni-MH Replacement Battery

This is a 7.2V 2000mAh Ni-MH battery for Palfinger wireless crane remote controls. It fits the 590, 960, EEA2512, and 790 models, along with five additional remotes in this series. Voltage and cell chemistry match the OEM spec exactly.

• Cross-model fit — 590, 960, EEA2512, 790 and more: These remotes share a common 7.2V Ni-MH power architecture with the same connector format and cell arrangement. A single battery design covers the full range because the voltage rail and BMS communication protocol are consistent across this Palfinger remote family.
• Bench tested on actual hardware: We cycled this battery through full charge and discharge sequences on compatible Palfinger remote hardware. The BMS accepted charge without fault flags, and output voltage held steady across solenoid activation events that typically spike current draw.
• Monthly charge during idle periods: Crane remotes often sit unused for weeks between jobs. Ni-MH cells left uncharged for extended periods will self-discharge below the recovery threshold. Charge this battery at least once a month during idle periods — cells dropped too low may not recover to usable capacity even after reconnecting the charger.

Solenoid activation causing power dropout on a freshly installed battery

When a crane remote triggers a solenoid or relay, the inrush current spikes sharply for a fraction of a second. If the battery is at partial charge, internal resistance is higher and the voltage can sag below the remote's cutoff threshold. The BMS interprets this sag as a fault and shuts down the output. Charge the battery fully before operating — at 7.2V Ni-MH, that means reaching the trickle phase on the charger, not just the green indicator light.

Remote shows low battery immediately after swapping in a new cell

New Ni-MH batteries ship at storage voltage — typically 60–70% of rated capacity. The Palfinger remote reads this as low and flags it immediately. This is not a fault with the battery. Connect the battery to the OEM charger and run a full charge cycle before use. Once fully charged, open-circuit voltage should read between 8.4V and 8.7V across the pack terminals.
