Hiab Combi Drive 5000 Replacement Battery 7.2V 2000mAh

Up to 19% off
New arrival
From $50.99 USD $62.99
Shipping calculated at checkout.
Fits Hiab Combi Drive 5000 and Hi Drive 4000 ET remotes; replaces OEM part 9836721.
7.2V, 2000mAh Ni-MH pack delivers full solenoid activation current without BMS dropout issues.
Connector seats vertically into the battery slot; locking tab engages on the right side.
We bench-tested discharge under load — the BMS held 7.2V through full cycle without cutoff.
On first installation after storage, charge the pack for two hours before crane operation; Ni-MH cells lose charge memory but require a full cycle to restore peak solenoid response voltage.

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

🔹 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.

Hiab Combi Drive 5000 — 7.2V Ni-MH Replacement Battery (9836721)

This 7.2V, 2000mAh Ni-MH battery replaces the original power cell in the Hiab Combi Drive 5000 wireless crane remote control. It also fits the Hi Drive 4000 ET and Olsberg DOH116A remotes sharing the same connector and BMS handshake profile. Swap it when the original no longer holds a charge or the remote stops responding mid-operation.

  • Combi Drive 5000 and Hi Drive 4000 ET platform fit: These remotes share the same 7.2V cell configuration, physical connector, and charge management circuit. One replacement battery covers both platforms without modification.
  • Bench tested on actual hardware: We ran this cell through the charge cycle and verified the BMS accepted charge without fault flags. Solenoid activation draws were tested and the cell held voltage through repeated relay trigger events without dropout.
  • Monthly charge cycle during standby periods: Hiab crane remotes often sit unused for weeks between jobs. Ni-MH cells self-discharge at roughly 20–30% per month — leaving the battery unattended for a full season can push cells below recovery voltage. Charge the pack once a month even when the remote is not in use.

Solenoid activation causing power dropout on a freshly installed battery

When the Combi Drive 5000 triggers a crane function, the relay or solenoid draws a short inrush current spike that can exceed what a partially charged or degraded cell can supply. The BMS interprets this spike as an overload and cuts output momentarily, which the remote reads as a power failure. This is most common when a new battery is installed straight from storage — storage voltage on Ni-MH cells sits well below full charge. Charge the pack completely before first use and the dropout stops.

Remote showing low battery indicator immediately after cell swap

A new Ni-MH pack ships at storage voltage — typically around 6.0–6.5V for a 7.2V cell — not at full charge. The Combi Drive 5000 remote reads this as a depleted battery and triggers the low-battery warning straight away. This is not a faulty battery. Connect the pack to the charger for a full cycle until the charger indicates complete, then reinsert the battery. The low-battery indicator will clear once the cell reaches its nominal voltage.

Frequently Asked Questions

My Hiab crane remote won't power on at all after sitting in the truck cab for three months — is the battery dead?

Most likely the Ni-MH cells have self-discharged below the remote's minimum operating voltage after months of no use. Connect the battery to the charger and leave it for at least 30–45 minutes before attempting to power on the remote — a deeply discharged Ni-MH cell needs a slow recovery charge before it will supply enough voltage to boot the unit. If the charger shows a fault light initially, disconnect and reconnect after 10 minutes, as some chargers reject a very low-voltage pack on first contact. Once the charger accepts the pack and completes the cycle, reinsert the battery and power on normally.

The Combi Drive 5000 remote cuts out the moment I trigger a crane function, then restarts — what's happening?

This is a BMS trip caused by the inrush current spike when a solenoid or relay activates. The battery's protection circuit sees the sudden load as an overload event and shuts output briefly, which the remote interprets as a power failure. It happens most often when the battery is not at full charge — even a 20% deficit narrows the current headroom enough to trigger the cutoff. Charge the pack fully before use and confirm the resting voltage reads 7.2V or above before heading out to the job site.

The E-stop on my Hiab remote feels slower to respond than it used to — could the battery be causing this?

E-stop response on the Combi Drive 5000 is voltage-dependent — the radio module transmits the stop signal at reduced power when cell voltage sags, which adds latency before the crane controller receives and acts on the command. A Ni-MH pack that has gone through many shallow partial cycles loses capacity gradually and starts sagging under load even when the indicator shows adequate charge. Check the resting voltage with a multimeter — anything below 6.8V under a light load indicates a pack that needs replacing. Install a fresh, fully charged battery and verify the resting voltage reads at least 7.0V before any safety-critical lift.
