Battery Care Tips
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
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.

Sony NP-FH90 — 7.4V Li-ion Replacement Battery
This is a 7.4V, 2200mAh Li-ion replacement for the Sony NP-FH90 battery. It fits the CR-HC51E, DCR-30, DCR-DVD92, DCR-DVD92E, and over 220 additional Sony camcorder and camera models. Cell capacity matches OEM spec at 16.28Wh.
- Broad Sony camcorder compatibility: These models share the same 7.4V rail, InfoLITHIUM communication protocol, and physical connector pinout — which is why a single NP-FH90 cell spans such a wide model range without voltage or fit issues.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on compatible Sony bodies. The BMS handshook correctly, the InfoLITHIUM percentage readout initialised, and protection circuits tripped at the expected low-voltage threshold.
- First-use charge cycle on CR-HC51E and DCR series bodies: Run the first charge from inside the camera body using the OEM charger or USB connection — not a third-party external charger. The Sony BMS maps its battery-remaining display against the cell's discharge curve during this initial cycle. Skipping it causes erratic percentage readings from the first session.
Sony InfoLITHIUM authentication and why new cells get rejected on first install
Sony's InfoLITHIUM system does more than report percentage — it actively handshakes with the cell over the data pin before allowing the body to draw current. A brand-new cell that has never been through a full charge cycle on that specific body can fail this handshake and throw an incompatible or no-battery warning. The fix is straightforward: seat the battery, insert it into the charger or camera, and let it complete one full charge cycle without interruption. After that single cycle, the body maps the cell and the warning clears. This is a BMS initialisation step, not a fault with the replacement cell.
Battery percentage jumping or resetting during recording
When the Sony body's stored discharge curve doesn't match the new cell's actual voltage-versus-capacity profile, the percentage indicator recalculates mid-session and jumps — sometimes dropping 20% in seconds or resetting to a higher number. This happens because the body interpolates remaining capacity from voltage thresholds it learned from the previous cell. Two full charge-discharge cycles on the body recalibrates the map. After the second cycle, the indicator tracks steadily from 100% down to the 6.8V low-voltage cutoff.

Frequently Asked Questions
My Sony camcorder shows "incompatible battery" immediately after I fit the new NP-FH90 — is the cell faulty?
The cell is not faulty. Sony's InfoLITHIUM data pin requires a handshake before the body enables power draw, and a new cell that has never been initialised on that body will fail it on the first insert. Place the battery in the OEM charger or in the camera body itself and run one full charge cycle without removing it early. After that single uninterrupted cycle the body accepts the cell and the warning clears.
The battery percentage on my DCR-DVD92 drops sharply then jumps back up mid-recording — what's causing that?
The body is interpolating remaining capacity from voltage thresholds it mapped against the old cell's discharge curve. A new cell with a slightly different curve at mid-charge voltages causes the percentage indicator to recalculate and jump. Run two complete charge-discharge cycles on the camera body — not an external charger — so the BMS can remap against the new cell's actual voltage profile. After the second cycle the readout tracks steadily down to the 6.8V cutoff.
Shot count is noticeably lower than expected in cold weather — is this a capacity problem with the replacement cell?
It is not a defect. Li-ion cells lose usable capacity below 10°C because electrolyte ion mobility drops, raising internal resistance and compressing the discharge curve. The full 2200mAh is still present but the body's low-voltage cutoff trips earlier before the cell can deliver it at the reduced current. Keep the battery in an inner pocket until just before shooting, and let the camera warm to ambient before extended use — recoverable capacity returns once the cell reaches room temperature.
