OHYES BAT RRY08L 40V 7.5Ah Replacement Battery with LED Display
Product description
Lithium-ion construction gives the OHYES BAT RRY08L a 40V format for compatible Ryobi cordless power tools. Its 7.5Ah capacity and LED charge indicator make it straightforward to check the battery’s status as part of your regular tool setup.
This replacement is listed for a range of Ryobi 40V battery and device models. That makes the specific model list useful when choosing a replacement for a tool or pack you already own.
The indicator lights show remaining battery status, including when the pack is fully charged or needs charging. Built-in safeguards address incorrect voltage, overload, short circuit, and internal overheating.
Tech summary
- Type: Lithium-ion replacement battery
- Voltage: 40V
- Capacity: 7.5Ah (7500mAh)

The listed capacity and voltage identify the pack for shoppers comparing replacement batteries by their tool’s power system and battery requirements.
Compatibility
The RRY08L is listed as a replacement for Ryobi 40V battery models OP4050A, OP4015, OP40201, OP40261, OP4030, OP40301, OP4040, OP40401, OP4050, OP40501, OP40601, OP40602, and OP4060A.

Looking for a replacement that matches a specific Ryobi battery code? Use the model number printed on your existing battery or tool to compare it with this list before choosing. This is a practical way to distinguish a broadly compatible 40V replacement from a battery intended for a different tool platform.
Tips for day-to-day use
Check the LED status before taking the battery to a job, then recharge it when the indicator shows that charging is needed. For a work setup with more than one compatible tool, matching the battery and charger to the models listed above helps keep the replacement within its stated use. The charge indicator also gives a simple visual reference when you set the pack aside between tasks.
The built-in safeguards are designed to address incorrect voltage, battery overload, short circuit, and internal overheating. Keep the battery and compatible charger together as part of your regular tool routine, and use the status lights to see whether the pack is ready or needs charging.
Is it worth it?
For someone replacing a Ryobi 40V battery, the useful distinction here is the combination of a 7.5Ah lithium-ion pack, LED status display, and a clearly listed range of compatible battery and tool models. Instead of selecting a replacement solely by voltage, compare the model codes against your current setup and choose this pack when they match. Its charge indicator adds a practical check for everyday cordless work, while the named compatibility list helps narrow the choice to the intended Ryobi system. A solid pick if you need a 40V replacement for a listed device and want an at-a-glance battery status display.
