Pentax D-LI96 WG-1000 Replacement Battery 3.7V 890mAh

Up to 20% off
New arrival
From $40.99 USD $50.99
Shipping calculated at checkout.
Fits Pentax WG-1000 rugged camera, replaces OEM D-LI96 battery pack.
3.7V and 890mAh capacity powers the imaging sensor through extended outdoor shoots without voltage sag.
Connector slides straight in; no locking tab — seat it flush until you hear the contact catch.
We bench-tested this cell in the WG-1000 body; BMS accepted the new pack on first charge cycle with no authentication delay.
On first use, run one full charge cycle inside the camera body before heavy shooting — Pentax BMS requires an in-body charge to map the discharge curve for accurate battery-remaining display.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

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.

Pentax WG-1000 — 3.7V Li-ion Replacement Battery (D-LI96)

This is a 3.7V, 890mAh Li-ion cell matching the D-LI96 specification for the Pentax WG-1000 rugged compact camera. It fits the WG-1000 body directly and restores full camera operation when the original cell has degraded. Voltage and capacity match the OEM spec exactly.

  • WG-1000 compatibility: The WG-1000 uses a single D-LI96 cell to power the imaging sensor, LCD, and onboard processor from one 3.7V rail. The connector and cell dimensions — 41.35 × 34.00 × 6.80mm — must match for the battery door to close and the BMS to register the cell correctly.
  • Bench tested on actual hardware: We ran this cell through a full charge cycle and confirmed the BMS accepted the cell, reported a valid battery state, and discharged without triggering a low-voltage cutoff prematurely. Charge acceptance and terminal voltage held within spec at both cold and ambient temperatures.
  • First-install charge cycle on the WG-1000: Charge the new cell inside the camera body using the OEM charger or USB port before shooting. The WG-1000 BMS maps its battery-remaining display against a full discharge curve — skipping this step can cause the indicator to read inaccurately for the first several cycles.

Why the WG-1000 battery indicator jumps around after fitting a new cell

The WG-1000 uses a voltage-threshold table to estimate remaining charge. A new cell has a slightly different discharge curve slope than the aged OEM cell the camera previously calibrated against. Until the BMS has seen one or two complete discharge and recharge cycles with the new cell, the percentage readout maps incorrectly to the actual voltage. This resolves after two to three full cycles — no fault with the cell itself.

Flash not fully recycling between shots on a new D-LI96 cell

Flash recycling draws a spike of current to recharge the capacitor between shots. If the cell voltage sags under that current draw, the capacitor takes longer to reach full charge and the camera delays the next shot or fires at reduced output. On a new cell this usually means the BMS has not yet accepted the cell fully — charge it once inside the camera body via the OEM charger. If the issue persists after two full cycles, check that terminal voltage under no load reads at least 3.6V.

Frequently Asked Questions

My WG-1000 shows a dead battery icon immediately after fitting the new D-LI96 — is the cell faulty?

Almost always no. The WG-1000 BMS runs an authentication check on first install and may reject an unrecognised cell until it has seen a charge cycle from inside the camera body. Place the battery in the camera, connect the OEM charger or USB cable, and let it complete a full charge before powering on. After that cycle the camera should recognise the cell and display a valid charge level.

The battery percentage on my WG-1000 jumps from 60% to 20% mid-shoot — what's causing that?

The camera's indicator is reading voltage thresholds calibrated against the discharge curve of the original cell. A replacement cell discharges along a slightly different curve, so the percentage mapping drifts at mid-range voltages where the slope is flattest. Run two complete charge and discharge cycles — charge fully, shoot until the camera shuts down, repeat — and the BMS will remap against the new cell's curve. After that, the readout stabilises.

My WG-1000 depletes the new battery much faster in cold weather than at room temperature — is something wrong?

Nothing is wrong with the cell. Li-ion internal resistance rises sharply below 10°C, which reduces the usable capacity the BMS can draw before hitting its low-voltage cutoff. The WG-1000 is rated for outdoor use but the battery chemistry itself is the limiting factor in the cold. Keep the camera inside a jacket pocket between shots to hold the cell above 5°C, and you will recover most of the rated 890mAh capacity.
