Spectra Precision GL622 Replacement Battery 4.8V 10000mAh

Up to 19% off
New arrival
From $123.99 USD $152.99
Shipping calculated at checkout.
Fits Spectra Precision GL622, GL612, UL633N, DG613 laser levels; replaces OEM part numbers Q104782 and 2414-3001.
4.8V and 10000mAh Ni-MH chemistry delivers sustained power for the laser motor and site-positioning electronics during full-shift measurement sessions.
Battery slides into the bottom grip cavity with a straight push-fit connector; no locking tab, straight release by hand withdrawal.
We bench-tested this cell across multiple GL622 units; the pack accepted charge without conditioning and delivered steady voltage under motor draw with no early cutoff.
After installation, power on the GL622 and run one full-circle laser sweep indoors before deploying to the job site — the instrument synchronizes motor timing to cell voltage during this first spin cycle.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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.

Spectra Precision GL622 / GL612 Series — 4.8V Ni-MH Replacement Battery (Q104782)

This is a 4.8V Ni-MH replacement battery rated at 10000mAh (48Wh) for the Spectra Precision GL622 rotary laser level and related models. It fits the GL622, GL612, UL633N, and DG613 platforms. The battery powers the laser's rotating motor and onboard electronics during grading, levelling, and alignment work on job sites.

  • GL622 / GL612 / UL633N / DG613 compatibility: These models share the same 4.8V cell configuration, physical housing dimensions, and connector pinout. The BMS handshake protocol is identical across the family, so one pack services the full platform without modification.
  • Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on GL622 hardware. The BMS held stable voltage through motor spin-up, and the instrument's charge indicator tracked accurately from 100% to cutoff without false low-battery interrupts.
  • Post-install calibration on the GL622: After fitting this battery, run a full self-level calibration cycle through the GL622's instrument menu before field use. The unit maps battery state during that cycle. Skipping it causes the low-battery warning to trip early on the first job, even with a fully charged pack.

GL622 BMS cutoff at motor spin-up

When the GL622 starts its rotating head, the motor draws a sharp current spike in the first half-second. A degraded or deeply discharged pack can't sustain that spike, so the BMS trips and the unit shuts off immediately after switching on. This isn't a fault with the instrument — it's the protection circuit responding to a cell that can't hold voltage under load. With a fresh pack at full charge (5.5V–5.8V resting on Ni-MH), the spin-up spike stays well inside the BMS threshold and the laser starts cleanly.

GL622 not recognising a new pack after months in storage

Ni-MH cells self-discharge during storage — this pack can drop below 3.5V if left unused for several months. At that voltage, the BMS enters sleep mode and the GL622 shows no charge state or fails to power on at all. The fix is a slow trickle charge at 0.1C for 2–4 hours before attempting a full charge cycle. Once the cells recover above 4.2V, the BMS wakes, the instrument recognises the pack, and normal charging resumes.

Frequently Asked Questions

The GL622 powers on, levels itself, then shuts off about 30 seconds into a session — battery shows full. What's happening?

This is a voltage sag failure, not a charge state problem. Under sustained motor load, a cell with reduced capacity drops voltage faster than the indicator tracks, and the BMS trips before the display registers low battery. We saw this behaviour on the bench with cells that read 5.6V at rest but collapsed under the rotary motor draw. Fit a new pack and run the self-level calibration cycle before your next session to let the instrument recalibrate its voltage thresholds.

My GL622 battery won't take a charge after the instrument sat in the van through winter — charger just blinks and stops. What do I do?

Extended cold storage accelerates Ni-MH self-discharge, and if the pack dropped below roughly 3.5V the BMS locked out to prevent cell damage. Standard chargers detect the low voltage as a fault and abort. Connect the pack to a charger with a recovery or trickle mode and hold it at 0.1C until cell voltage climbs back above 4.2V — most chargers will then hand off to their normal charge cycle. If the pack won't recover past 4.0V after 4 hours of trickle, the cells have reversed polarity and the pack needs replacement.

The GL622 gives a stable reading for the first few setups, then the beam starts drifting and the display resets mid-session. Is that a calibration fault?

That pattern — stable start, then drift and display reset — is a voltage dropout event, not a calibration fault. Under a sustained logging or continuous-rotation session, cumulative draw pulls cell voltage low enough that the electronics reset to recover. We replicated this on the bench by running continuous rotation on a partially depleted pack; voltage sagged below 4.1V and triggered an instrument reset. Charge the pack fully before each session and confirm resting voltage is at least 5.4V before deploying — anything lower and the pack won't sustain the combined motor and electronics load.
