Fujifilm NP-48 XQ1 Replacement Battery 3.6V 850mAh

Up to 21% off
New arrival
From $22.99 USD $28.99
Shipping calculated at checkout.
Fits Fujifilm XQ1 and XQ2 compact cameras, replaces OEM part NP-48.
3.6V lithium-ion cell rated 850mAh delivers the same charge capacity as original pack.
Connector slides straight into the battery chamber with a single locking tab on top.
We bench tested this cell in an XQ1 body; BMS accepted the new pack on first insertion without rejection errors.
On initial install, run one full charge cycle through the camera body before extended shooting — Fujifilm's fuel gauge needs that cycle to map accurately to this cell's discharge curve.

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.

Fujifilm XQ1 / XQ2 — 3.6V Li-ion Replacement Battery (NP-48)

The NP-48 is a 3.6V, 850mAh lithium-ion cell that powers the Fujifilm XQ1 and XQ2 compact cameras. It slots into the same battery compartment as the original and connects to the same three-contact interface. Use it as a spare to keep shooting when your primary cell runs down.

  • XQ1 and XQ2 compatibility: Both cameras share the same battery bay dimensions, contact layout, and BMS voltage thresholds — 3.6V nominal, 4.2V fully charged. One NP-48 cell works in either body without modification.
  • Bench tested on actual hardware: We ran this cell through the XQ1 body and confirmed the BMS accepted the cell, reported charge state correctly, and held the protection circuit within expected cutoff parameters at both low and high charge boundaries.
  • First-cycle charging on the XQ1 or XQ2: Charge the new cell inside the camera body using the OEM USB cable before your first shoot. Some Fujifilm BMS firmware maps the battery-remaining indicator to the discharge curve during the first in-body charge cycle — skipping this step can cause the indicator to read inaccurately.

Why the XQ1 battery indicator jumps erratically with a new cell

The XQ1 maps its battery-remaining display to a voltage-threshold table calibrated against the original cell's discharge curve. A new replacement cell may have a slightly different internal resistance profile, causing the camera to misread voltage at mid-charge levels. This shows as the indicator jumping from three bars to one bar and back without warning. Running one full charge-discharge cycle in the camera body lets the firmware re-anchor its thresholds to the new cell — after that, the display stabilises.

Flash not fully recycling between shots on a new NP-48

The XQ1 flash capacitor draws a short, high-current pulse to recharge after each fire. If the camera body is cold or the cell hasn't reached a stable operating temperature, internal resistance rises and the capacitor recharge current sags. The result is a longer-than-normal recycle gap or a weaker flash output on back-to-back shots. Warm the battery to room temperature before shooting in cold conditions — above 10°C the cell delivers the full recharge current the capacitor needs.

Frequently Asked Questions

My XQ1 shows a dead battery icon immediately after fitting a new NP-48 — is the cell faulty?

Not necessarily. The XQ1 BMS runs an authentication and voltage-range check when a new cell is inserted, and a cell sitting at storage charge (around 3.7–3.8V) can trigger a false low-battery reading on first insertion. Insert the cell, connect the camera to its OEM USB charger, and let it charge to 4.2V before powering on. After one full charge the BMS accepts the cell and the indicator reads correctly.

Shot count seems lower than expected — I'm not getting anywhere near as many shots as I did with the original battery.

The XQ1's rated shot count assumes minimal flash use and short review periods, but in practice the f/2.0 lens's continuous AF, the EVF-equivalent display refresh, and even image stabilisation all pull additional current well beyond the baseline spec. Flash use is the biggest variable — each pop draws a capacitor recharge pulse that consumes significantly more than a standard shutter cycle. Track a shoot with flash disabled and you'll see the cell last noticeably longer; the cell capacity at 850mAh is correct, the draw profile just varies more than the spec count implies.

Battery percentage on the XQ2 drops from 100% to around 60% in the first few shots, then levels out — what's happening?

This is a voltage-threshold mapping issue, not capacity loss. The XQ2 reads battery level by sampling cell voltage against a fixed table. A new cell's open-circuit voltage drops quickly from 4.2V through the upper band — the camera interprets that initial steep slope as a large capacity drop. Below roughly 3.9V the discharge curve flattens and the indicator stabilises. Complete two full charge-discharge cycles in the camera body and the displayed percentage will track more evenly across the full charge range.
