Kastar 4-Pack Battery Replacement for RCA CC-634 CC-636 - Long Life

In this review the Kastar 4-Pack Battery Replacement is assessed for users who need reliable, long-running power for older RCA and compatible camcorders. The bottom line: this Ni-MH 6.0V 2100mAh pack is best for photographers and hobbyists who want a high capacity, eco-friendly spare without fuss. The reviewer found the pack delivers extended runtime and better standby retention than typical cells, so it reduces mid-shoot swaps and gives confidence for longer shoots and travel.

Key Features

• High Capacity: The 2100mAh rating provides noticeably longer run time than standard replacements, reducing battery swaps during shoots.
• Ni-MH Chemistry: The eco-friendly Ni-MH cells avoid Hg/Cd/Pb and are a safer option for users mindful of environmental impact.
• Low Self-Discharge: Built with an embedded seal structure to hold charge longer in storage, so batteries are ready when needed.
• Safety Assurance: Added mix-protection additive extends cycle life up to 1200 cycles, improving durability under frequent charge/discharge.
• 4-Pack Convenience: Four identical batteries in one package make it simple to keep multiple spares on hand for longer outings.

Who It's For

This pack suits owners of older RCA camcorders and compatible Pentax and Philips models who need a dependable, higher-capacity replacement battery for extended recording or field use. Hobby videographers, event shooters, and anyone who prefers replaceable cells over proprietary battery systems will find the 4-pack particularly practical.

Those who require the absolute lightest weight or a proprietary manufacturer battery with model-specific firmware should look elsewhere. Also, if a camera demands a different voltage or a non-Ni-MH chemistry, this pack will not be suitable.

Pros & Cons

Pros

• Longer run time from the 2100mAh capacity compared with many generic replacements.

• Low self-discharge design means batteries retain usable charge in storage.
• Four batteries in one pack reduces the need to buy multiple single cells.

Cons

• Not a fit for devices that require proprietary battery firmware or different voltages.
• Ni-MH requires periodic charging and may not match lithium-based runtime by weight.
