Kastar 3-Pack 2400mAh Lithium-Ion Batteries with AC Charger - Medium

In this review the Kastar 3-Pack 2400mAh Lithium-Ion Batteries with AC Charger is presented for photographers who use Mamiya and Mamiya Leaf medium format camera backs and need reliable spare power. The bottom line: this kit delivers three matched 7.4V, 2400mAh replacement batteries and a compact AC wall charger that accepts 100~240V input, making it a sensible purchase for studio shooters and field photographers who want multiple ready batteries without hunting down original-brand packs. For anyone who regularly shoots tethered sessions or long runs, the included charger and LED status reporting simplify keeping spares charged and organized.

Key Features

• Battery Capacity: Each battery is 2400mAh which provides extended shooting time compared with many smaller third-party cells.
• Voltage Compatibility: The 7.4V lithium-ion chemistry matches the original equipment power requirements for the listed Mamiya Leaf models.
• Universal Charger Input: The AC charger accepts 100~240V 50~60Hz input so it can be used internationally with a local adapter.
• Charge Status LED: The charger uses a red LED during charging and a green LED when standby or fully charged, making it easy to tell battery status at a glance.
• Pack Convenience: The kit includes three batteries and one foldable-pin AC charger so photographers have immediate spares and a compact charger for storage.

Who It's For

This kit is aimed at professional and advanced amateur photographers who shoot with Mamiya Leaf and Mamiya medium format backs such as the Aptus-II and AFi-II series and need multiple replacement batteries for long sessions or travel. Its combination of three batteries and a single compact charger is useful for studio tethering, location work, and multi-back setups where swapping batteries quickly reduces downtime.

Photographers who require an in-vehicle charging option or included international plugs should look elsewhere, since the package does not include a car adapter or European plug. Also, buyers who insist on OEM-branded batteries for warranty parity may prefer original manufacturer power packs.
