CGR-D28 2-Pack 3300mAh Replacement Batteries with AC Charger - Long

In this review the reviewer tested the Kastar 2-Pack CGR-D28 battery kit to see if it provides dependable runtime and simple charging for older Panasonic camcorders and compatible models. The bottom line: this kit is for videographers and camera owners who need a pair of higher-capacity replacement batteries plus a compact wall charger to keep projects moving without hunting for proprietary parts. The biggest reason to buy is clear - two 3300mAh lithium-ion cells and a foldable AC charger give extended shooting time and a convenient charge option that fits into a camera bag.

Key Features

• 3300mAh Lithium-Ion: The higher 3300mAh capacity delivers longer recording sessions than many original lower-capacity packs, reducing the need to swap batteries during shoots.
• 7.4V Output: The batteries match the expected 7.4V specification for CGR-D28 compatible camcorders, ensuring correct voltage for stable operation.
• Foldable AC Charger: The included wall charger has a foldable flat pin that tucks away for neat storage and easy transport in a gear bag.
• Wide Input Range: Charger input of AC 100~240V 50~60Hz supports use in different regions when paired with the correct local adapter or plug set.
• LED Charge Indicator: A red LED indicates charging while a green LED shows standby or full charge, making it simple to monitor progress at a glance.
• Package Convenience: The kit ships with two batteries plus one AC charger, providing an immediate replacement solution without needing to buy parts separately.

Who It's For

This kit is aimed at owners of compatible Panasonic and related camcorders who want a straightforward replacement battery solution with more capacity. Independent videographers, event shooters, and anyone maintaining older camera kits will appreciate getting two batteries to extend run time between charges.

Those who need vehicle charging accessories or specific international plugs should note the package does not include a car adapter or European plug; buyers who require those should look for a bundle that explicitly lists them or plan to purchase adapters separately.
