Palfinger 590 Crane Remote Replacement Battery 7.2V 3000mAh

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

This is a 7.2V 3000mAh Ni-MH replacement battery for Palfinger wireless crane remote controls. It fits the 590, 960, 790, EEA2512, and additional Palfinger remote models. The battery restores power to remotes used to operate Palfinger hydraulic cranes and material handling equipment on job sites.

• Multi-model Palfinger remote fit: These Palfinger remote units share the same 7.2V voltage rail, physical cell pack format, and connector pinout across the 590, 960, 790, and EEA2512 platforms. No BMS handshake is required — the remote accepts the cell pack directly through the housing contacts.
• Bench tested on actual hardware: We cycled this pack through load tests simulating solenoid activation bursts. The Ni-MH cells held stable voltage under repeated high-current draws without triggering cutoff, and capacity landed within 5% of the 3000mAh rating across three full discharge cycles.
• Storage charge for infrequent crane use: Palfinger remotes on seasonal or project-based sites often sit unused for months. Ni-MH cells self-discharge at roughly 1–3% per day — a pack left uncharged for 60 days can drop low enough to lock the remote out. Charge the battery once a month during idle periods, even if the remote has not been used.

Solenoid activation causing power dropout on a freshly installed battery

Palfinger crane remotes trigger solenoid valves for boom and load movement. Each solenoid activation draws a short inrush current spike that can be 3–5 times the steady-state draw. If the battery is at storage voltage — typically around 7.0V for a fresh but uncharged Ni-MH pack — that inrush spike can pull the terminal voltage below the remote's cutoff threshold, causing the unit to drop out momentarily or reset. This is not a fault in the battery or the remote. Charge the pack to a full 8.64V (1.44V per cell across six cells) before operational use to eliminate the dropout.

Remote showing low-battery alert immediately after new cell install

A new Ni-MH pack ships at storage voltage — typically 60–70% charge — not full capacity. The Palfinger remote reads terminal voltage to estimate charge state, so a pack sitting at 7.0–7.2V registers as low even though the cells are not depleted. This is expected behaviour, not a defective battery. Connect the pack to the Palfinger charger and run a full charge cycle until the charger indicates complete before returning the remote to service.
