Lenovo IdeaPad Y400 series battery - Y400N Y400M Y400P Y410 Y410P Y490

This is a brand new Lenovo IdeaPad Y400 series Battery.

NOTE: If your laptop is the Lenovo 3000 series laptop, this is not the correct battery. Lenovo used the model numbers Y400 and Y500 in the earlier 3000 series laptops as well. This is confusing as the model number Y400 or Y500 can show up with different batteries. You can always check the battery itself to compare the shape of your battery to this battery.

This battery contains the very best Li-ion cells on the market from Samsung. An important specification to look for with rechargeable batteries is the mAh (mili amp hour) rating or Whr (Watt Hour). This battery is rated at 5200 mAh or 58 Whr. This is the highest rating available for a 6 cell battery pack. The higher the mAh rating, the longer your battery will run before it needs to be recharged again.
