About this replacement
Kodak PIXPRO S1 / AZ651 — 7.4V Li-ion Replacement Battery (LB-070)
This is a 7.4V, 1150mAh Li-ion replacement for the Kodak LB-070 battery. It fits the PIXPRO S1, PIXPRO S-1, PIXPRO AZ651, and PIXPRO AZ651 Astro Zoom cameras. Same voltage, same form factor, same connector as the original cell.
- PIXPRO S1 and AZ651 platform fit: These models share the same battery bay, connector pinout, and BMS communication protocol — all running from a common 7.4V Li-ion rail. One cell works across the whole group without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the PIXPRO platform. The BMS accepted the cell, reported charge state without lockout, and held voltage within spec across the discharge curve.
- First-cycle conditioning on camera BMS: On first install, run a complete charge cycle through the camera body or OEM charger before heavy shooting. The PIXPRO BMS maps battery-remaining percentage against the cell's discharge curve — skipping this step can cause the indicator to read erratically until the camera has calibrated against the new cell.
Flash output dropping mid-shoot on a freshly charged cell
The PIXPRO AZ651's flash capacitor draws a concentrated burst of current each recycle cycle. As the cell discharges past roughly 7.0V, recharge time for that capacitor increases — the camera may fire the flash at reduced output or delay the ready signal. This is voltage sag under capacitor load, not a faulty cell. Swapping to a freshly charged replacement mid-session is the fastest fix when flash lag becomes noticeable.
Battery percentage jumping erratically after fitting a new cell
The PIXPRO S1 maps its battery indicator against a discharge curve calibrated to the original cell. A new cell with a slightly different discharge profile can confuse that mapping — you may see the percentage jump from 80% to 40% with no warning. This is a calibration issue, not a defective battery. Run one full charge-to-empty cycle inside the camera body and the indicator will stabilise against the new cell's actual curve.
