41 Wh replacement battery for HP laptops

This 14.8 V lithium-ion pack replaces the original OA04 cell in numerous HP 14-inch and 15-inch notebooks. It targets owners of HP 240, 245, 246, 250, 255 and 256 series machines who need a direct swap for a worn-out unit. The black 4-cell design matches the factory voltage and connector layout.

Simple bay swap with built-in protection

Installation consists of releasing the battery latch, sliding the old pack out and clicking the new one in; no tools or firmware steps are required. The integrated protection circuit guards against over-charge, over-discharge and short circuits, reducing the risk of damage from a faulty connection. Misaligned insertion is the only common error, so verify the notch orientation before applying pressure.

41 Wh capacity for everyday workloads

The 41 Wh rating restores typical office and web-browsing runtime to the level of a fresh factory battery. Intensive tasks such as video rendering or gaming will drain the pack more quickly, and users needing all-day mobility without a charger should consider a higher-capacity alternative if their chassis supports it.

Questions about this item

How can I verify the 41Wh 14.8V battery is working after installing it in my HP 250 G3?

Power on the laptop, open the battery report in Windows, and confirm the design capacity reads 41Wh with a 14.8V rating and four cells detected.

What comes in the box and do I need to buy any tools or cables separately for the HP 240 G3 replacement?

The package contains the 4-cell 41Wh black battery only; no screwdrivers, cables or adapters are included, so have a small Phillips screwdriver ready for the swap.

Which part number should I choose between OA04, 746641-001 and HSTNN-LB5Y for my HP 15-r011dx?

All three part numbers refer to the same 41Wh 14.8V 4-cell pack; pick the one that matches the label on your original battery.
