2 Packs 6.0Ah 40 Volt OP40601 OP40602 Battery Replacement - Longer

In this review of the 2 Packs 6.0Ah 40 Volt OP40601 OP40602 replacement battery, the bottom line is simple: it is for Ryobi 40V tool owners who need affordable, higher-capacity spares to extend runtime. The reviewer found these batteries deliver a clear runtime improvement over stock 40V packs thanks to the upgraded 6000mAh capacity, they fit a wide range of Ryobi 40V mowers, trimmers and blowers, and they include a convenient 4-LED charge indicator. For users who value runtime and compatibility more than OEM branding, this pair represents a practical value buy.

Key Features

• 6000mAh Capacity: The upgraded 6.0Ah cells provide noticeably longer runtime compared with many standard 40V packs, reducing the need to swap batteries mid-job.
• Wide Compatibility: Works with a broad list of Ryobi 40V cordless tools including mowers, trimmers, blowers and more, so one purchase covers multiple machines.
• Built-in LED Charge Indicator: Four LED lights on each pack let users check remaining power quickly so they can plan work and charging stops.
• Lithium Ion Chemistry: The lithium ion design minimizes memory effect and keeps self-discharge low, maintaining capacity during storage.
• Pack Quantity: Sold as two batteries, this kit is useful for users who need backup power or who run multiple tools in succession.

Who It's For

This pack is aimed at homeowners and yard care pros who already own Ryobi 40V tools and want more runtime without buying OEM batteries. It is especially good for tasks that need sustained power like lawn mowing or extended trimming sessions, and for anyone who likes having a spare battery ready to swap in.

Those who should look elsewhere include buyers who require manufacturer warranty parity or official OEM branding, or users tied to a specific rapid charging system not listed as compatible. Also avoid these if you need a battery narrower than standard Ryobi 40V form factors, since this product follows the common pack design.

Pros & Cons

Pros

• Higher 6000mAh capacity gives longer run times per charge compared with many standard 40V packs.

• Fit and quality get positive feedback from users, including compatibility with some dual rapid chargers.

Cons

• Longevity is mixed in customer reports, with a few users noting premature failures after limited use, so long-term durability may vary.
• Not an OEM-branded pack, which may matter to buyers who prefer official manufacturer support and warranties.

Specifications
