NiKon EN-EL1 Coolpix 4300 Replacement Battery 7.4V 700mAh

NiKon Coolpix 4300 / 4500 / 4800 / 5000 — 7.4V Li-ion Replacement Battery (EN-EL1)

This is a 7.4V, 700mAh Li-ion replacement for the NiKon EN-EL1 battery. It fits the Coolpix 4300, 4500, 4800, and 5000 series compact digital cameras, along with eight additional compatible models. Capacity is rated at 5.18Wh, matching the original cell specification.

• Coolpix 4300 / 4500 / 4800 / 5000 platform fit: These models share the same EN-EL1 form factor, contact layout, and 7.4V voltage rail. The battery slot, locking tab, and BMS communication protocol are identical across the range, so one cell covers the full group.
• Bench tested on actual hardware: We ran this cell on a Coolpix 5000 body through a full charge and discharge cycle. The BMS accepted the cell without fault codes, battery-remaining display tracked normally through the discharge curve, and charge termination triggered cleanly at capacity.
• First-install charge cycle on Coolpix bodies: Charge this cell inside the camera body using the OEM charger or AC adapter before your first shoot. The Coolpix BMS maps its battery-remaining indicator during that initial in-body charge — skipping it can cause the indicator to read incorrectly for the first several sessions.

Flash recycling slowing down before the cell reads empty on the Coolpix display

The Coolpix built-in flash draws a sharp burst of current to recharge its capacitor between shots. As a Li-ion cell ages or reaches the lower end of its discharge curve, internal resistance rises. That resistance causes a voltage sag during capacitor recharge, which the camera interprets as insufficient supply — recycling time increases even though the indicator still shows charge remaining. On the EN-EL1 platform, this sag typically becomes noticeable below 7.0V under load. Replacing the cell restores fast recycling because a fresh cell holds voltage through that current spike.

Battery percentage jumping erratically on the Coolpix display after fitting this cell

The Coolpix battery indicator maps voltage thresholds from the OEM EN-EL1 discharge curve. A new replacement cell may have a slightly different discharge profile, so the indicator can read high, then drop several bars quickly as the camera re-learns where the voltage steps fall. This is a calibration issue, not a faulty cell. Run two full charge-discharge cycles — charge to full in the camera body, shoot until the camera powers off — and the indicator will track accurately from the third cycle onward. After calibration, the display should hold steady across the 8.4V to 7.0V usable range.
