Canon NB-2L 7.4V 600mAh Li-ion Replacement Battery

Up to 20% off
New arrival
From $23.99 USD $29.99
Shipping calculated at checkout.
Fits Canon BP-2LH and NB-2L battery slots across PowerShot and EOS camera bodies from early 2000s models.
7.4V, 600mAh lithium-ion cell delivers stable voltage for autofocus, flash recycling, and continuous shooting without mid-session sag.
Connector slides straight into camera battery compartment with positive terminal forward and locking tab seated flush against the spring.
Bench testing showed clean BMS handshake on first insertion in Canon bodies; voltage curve tracks OEM discharge profile across full cycle.
On first use, run one complete charge cycle in the camera body itself before extended shooting — Canon's battery management system needs that initial cycle to map the new cell for accurate remaining-charge display.

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.

Canon BP-2LH / NB-2L Series — 7.4V Li-ion Replacement Battery (NB-2LH)

This is a 7.4V, 600mAh Li-ion cell that replaces the Canon NB-2L and BP-2LH battery across Canon PowerShot and EOS digital cameras from the early 2000s. It also fits Canon ZR800, ZR830, and ZR850 camcorder models, among 97 additional compatible devices. Voltage and cell chemistry match the original spec exactly.

  • Multi-model fit across PowerShot, EOS, and ZR series: These camera lines share the same 7.4V two-cell Li-ion pack format, the same physical connector orientation, and the same BMS handshake protocol — which is why one battery covers such a wide range of Canon bodies from that generation.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on Canon camera hardware. The BMS accepted the cell without fault flags, voltage held stable across the discharge curve, and the protection circuit tripped correctly at the low-voltage cutoff threshold.
  • First-use charge cycle in the camera body: Some Canon bodies from this era require the new cell to complete one full charge cycle inside the camera body — not just a wall charger — before the battery-remaining indicator displays accurately. Charge from within the camera body on first use.

Canon BMS rejecting a third-party cell on first install

Canon cameras in the PowerShot and EOS lines from this period use a BMS authentication check on first power-up with a new cell. If the body hasn't seen this cell before, it may throw a battery warning or refuse to power on entirely. This is a software handshake, not a hardware fault. Insert the battery, place the camera on the OEM charger for a full charge cycle, then power on — this sequence clears the authentication check on most affected bodies.

Battery percentage jumping erratically on the Canon display

Canon's battery indicator maps percentage to voltage thresholds calibrated against the original cell's discharge curve. A new replacement cell — even one at identical voltage — has a slightly different discharge curve shape, so the indicator can jump from 80% to 20% without warning. This is a calibration issue, not a capacity fault. Run two full discharge-and-charge cycles through the camera body to allow the BMS to remap its threshold table. After that, the percentage readout stabilises.

Frequently Asked Questions

My Canon camera powers off mid-shoot even though the battery indicator showed charge remaining — what's happening?

The battery indicator on these Canon bodies uses fixed voltage thresholds, and a cell that hasn't been calibrated yet can show charge remaining while the actual terminal voltage has already dropped below the BMS cutoff. This isn't a faulty cell — it's a calibration gap on a new replacement. Run two full discharge-to-cutoff and charge-to-full cycles through the camera body. After that, the BMS maps the new cell's curve and the shutoff behaviour becomes predictable.

Flash recycling is noticeably slower between shots than it was with the original battery — is that a cell fault?

Flash capacitor recharge draws a sharp current spike after each shot. If the cell is cold, partially discharged, or hasn't completed a calibration cycle yet, voltage sag during that spike extends recharge time. Check the cell is at room temperature and fully charged before shooting. If recycling is still slow after two full charge cycles, check terminal voltage under load — it should hold above 7.0V during active shooting on a healthy cell.

The camera reads this battery as fully charged immediately after I insert it without charging — should I trust that reading?

No. Some Canon bodies in this line will briefly display a full or near-full indicator when a new cell is first inserted because the BMS hasn't yet mapped the cell's actual state of charge. The reading reflects a default assumption, not a real measurement. Charge the battery fully in the camera body before shooting — wait for the charge indicator to confirm completion, then power on for an accurate starting readout.
