Replacement battery pack, 8.0Ah

The listed 8.0Ah capacity and four LED indicators give this two-pack a practical angle: more battery availability for compatible 40V tools, plus a quick way to check charge status. The listing identifies it as a lithium-ion replacement for several Ryobi 40V battery models, rather than as a Ryobi-branded battery. It also makes conflicting capacity claims, so the stated runtime advantage deserves a closer look before you choose it.

How to use it

This pack is intended for compatible 40V tools and chargers. The product name calls out OP4026, OP4026A, OP40201, OP40261, OP4030, and OP40301 batteries, the expanded compatibility description adds other models, including OP4050A, OP4040, and OP4060A. If you have a less common model, match its exact number against the seller’s full compatibility list instead of relying on the general 40V label.

A two-pack can be useful when one battery is charging while another is in use. For example, during a stretch of yard work, you could keep the second pack ready rather than stop to wait for a recharge. The four LEDs are meant to make a quick status check easier before you head outside. Do you need two replacement packs at once, though? If your tool sees occasional, short sessions, a single replacement may be enough and less battery than you need to manage.

Pros

• Two batteries are included according to the product name, which offers a ready spare for compatible tools.
• The listing specifies lithium-ion construction, 40V, and four charge-indicator LEDs.
• It describes overcharge, overcurrent, overvoltage, and overtemperature protection, according to the maker.
• A broad range of Ryobi 40V battery and charger model numbers is named, though exact fit still depends on the model.

You’ll appreciate it if you want a compatible replacement set and value having another pack available during longer jobs. It’s not for you if you need a clearly documented capacity per battery: the listing gives 8000mAh (8.0Ah) in its specifications but also refers to an upgraded 7500mAh capacity. That inconsistency makes runtime comparisons difficult, and the claim of twice the runtime is not something to treat as established from the information provided.

Spec sheet

• Name: OP4026A replacement battery pack
• Type: Lithium-ion replacement battery
• Format: 2-pack, as named in the product title
• Capacity: Listed as 8000mAh (8.0Ah), another section cites 7500mAh. It is not clear whether those figures refer to each battery.
• Voltage: 40V
• Energy: 320Wh, as listed
• Indicators: Four LED lights
• Protection features: Overcharge, overcurrent, overvoltage, and overtemperature protection are claimed.

This is a more ready-to-swap approach than buying one replacement pack, but the capacity discrepancy matters if your main reason for upgrading is longer runtime. The product name and detailed compatibility list also differ in which model numbers they highlight, so use the exact tool or charger number as your reference.

Final verdict

This replacement two-pack is worth considering if your Ryobi 40V setup matches the listed models and having a spare battery is useful in your routine. The LEDs and stated protection features add practical conveniences, but the capacity conflict is a meaningful drawback for anyone comparing runtime or expecting a specific capacity from each pack. If precise capacity documentation is essential, choose a replacement listing that states one consistent figure and clearly identifies whether it applies per battery.
