OHYES BAT 40V 8.0Ah Replacement Batteries, 2-Pack with LED Charge Indicators
Product description
Tech summary
Each OHYES BAT replacement battery is rated at 40V and 8,000mAh, giving compatible Ryobi cordless tools a high-capacity replacement option. The two-pack is useful when you want a second battery available for another tool or to rotate into a task while the other battery charges. Four built-in LED indicators show charge level at a glance, helping you decide when to recharge.

The batteries use NiMH cells and include protection against overcharging, over-discharge, overcurrent, and short circuits, along with a steady-voltage circuit. These features support everyday battery use and make charge status and basic protection functions part of the battery itself.

Who it’s for
This replacement set is for Ryobi 40V cordless-tool owners looking for two batteries with 8,000mAh capacity and clear charge-level indicators. The listed tool compatibility makes it easier to match the batteries to supported equipment, while the charger compatibility list helps identify supported charging setups before use.



For a yard or home project that involves several cordless tasks, two batteries give you the option to switch between them rather than relying on a single battery throughout the work. The LED indicators are practical between tasks: check the charge level and decide whether a battery is ready to use or should be placed on a compatible charger. If you’re choosing between a single replacement and a multi-battery set, this pack offers two batteries for managing more than one compatible tool or rotating batteries during work.
In the box

The set includes two 40V, 8,000mAh replacement batteries. Use them with the listed compatible Ryobi 40V tools and chargers. The battery’s LED indicators provide a quick visual check of its charge level, while the built-in protection functions are designed to address overcharging, over-discharge, overcurrent, and short circuits during use.
Should you buy it?
Choose this OHYES BAT two-pack if your cordless-tool setup uses a listed Ryobi 40V model and you want two replacement batteries with 8,000mAh capacity. Its strongest practical advantages are the two-battery format, four charge-level LEDs, and compatibility with specified Ryobi tools and chargers. It makes sense if you want a straightforward way to keep compatible cordless tools supplied with replacement batteries and monitor their charge between tasks.
