Key Features

• Battery Capacity: Each 2400mAh lithium-ion cell provides extended runtime compared with many OEM batteries, reducing the need to swap packs mid-session.
• Voltage Compatibility: The 7.4V battery voltage matches the original specification for Pentax D-Li50 compatible cameras, ensuring consistent performance.

• Wide Input Range: Charger input of AC 100~240V 50~60Hz makes it suitable for international use without a voltage converter.

Who It's For

This kit is best for enthusiast photographers and hobbyists using Pentax K10, K10D series, K20D or other cameras listed as compatible who want multiple replacement batteries and a single AC charger for home or travel. It is also useful for photographers who prefer to carry several spare batteries rather than rely on a single OEM pack.

Those who need a car adapter or European plug should note those extras are not included, so travelers relying solely on in-vehicle charging or needing multiple plug types should look for a kit with those accessories included.
