Kastar 4-Pack Battery Replacement for Memorex Model 155 - Long Runtime

In this review the Kastar 4-Pack battery replacement is evaluated for users who need reliable, longer-running power for older Memorex and compatible camcorders. The bottom line: this pack is best for hobbyists and professionals who want a straightforward, high-capacity Ni-MH swap with predictable runtime and long cycle life. The reviewer found the main selling point to be the high capacity 2650mAh cells that extend shooting time versus typical replacements, while maintaining low self-discharge so batteries hold charge when stored.

Key Features

• High Capacity: 2650mAh capacity provides noticeably longer run times for extended recording sessions without frequent swaps.
• Ni-MH Chemistry: The Ni-MH 6.0V construction delivers safe, well-understood performance across supported camcorder models.
• Low Self-Discharge: Embedded seal structure reduces self-discharge so batteries retain usable charge when left unused for weeks.
• Durability: Kastar adds mix-protection additives to slow cathode degradation and extend usable life toward the advertised cycle count.
• Value Pack: The 4-pack format is convenient for users who need spares for travel, multi-battery workflows, or house/field rotation.

Who It's For

The Kastar 4-Pack is ideal for owners of Memorex Model 155, Model 158 and the listed compatible camcorders who want a cost-effective way to increase on-camera runtime. It suits event shooters, videography students and small production crews who benefit from multiple ready batteries and prefer Ni-MH chemistry for safety and predictable behavior.

It is less appropriate for users who require manufacturer OEM branding or exact original-spec casing aesthetics, or for those who need the absolute lightest pack - this product focuses on capacity and longevity rather than ultralight design. If you need a lithium solution for extreme weight savings, look elsewhere.

Pros & Cons

Pros

• Higher 2650mAh capacity gives longer recording times compared with many standard replacements.
• Low self-discharge means batteries hold power between shoots, reducing pre-shoot charging needs.
• Protection additives and Ni-MH chemistry increase expected cycle life and reliability in regular use.

Cons

• Not an OEM battery, so fit and exterior finish may differ slightly from original brand packs.
• At 6.0V Ni-MH, it is heavier than comparable lithium options for portable ultralight setups.
