Compatible Nikon DSLR Kit

This two-pack of 2000mAh lithium-ion batteries and a dual-slot charger fits Nikon D40, D40x, D60, D3000 and D5000 digital SLR cameras. The cells match the original EN-EL9 and EN-EL9a form factor and voltage so they slot straight into the camera body. Photographers who need a lightweight spare set for day trips or backup power during events will find the capacity useful. It is not for shooters who require higher-capacity cells or compatibility with newer mirrorless mounts.

Drop-In Installation

Each battery is fully decoded and matches the OEM size, so installation is a simple swap in the camera battery compartment. The charger accepts two cells at once and shows red while charging and green when full or idle. The only common issue is forgetting to seat the battery contacts fully, which leaves the LED stuck on red. No firmware updates or calibration steps are required, though the pack lacks a built-in fuel gauge for on-camera percentage readouts.

USB Power Limits

The charger draws power through either a Micro-USB or USB-C port from any standard USB adapter, power bank, car charger or wall outlet. Output is limited to the 5 V USB bus, so charge speed depends entirely on the source you plug in. There is no fast-charge protocol support, and the 7.4 V battery voltage is generated internally from that 5 V input. Users who need simultaneous charging from a single low-current port may see longer wait times.
