This rechargeable lithium-ion battery packs 5200mAh of power into a slim 6-cell design, delivering reliable runtime for compatible IBM/Lenovo ThinkPad laptops. Drop it in your R500, R60, R60e, or R61 series to replace a worn-out original and get back to untethered work. It dodges single-use disposables, saving you cash over time while keeping e-waste in check. Backed by a 1-year limited warranty, it's a solid swap for the 40Y6799-ER part.
