The Best Laptop Batteries are at SafeBatteries.com - Advanced NNP Technology to Run and Last Longer!

Our Max Capacity laptop batteries are designed to provide value while exceeding both in capacity and cycle life performance. In fact, our laptop batteries far exceed most OEM laptop batteries! 


  • Saves you money by not having to replace your laptop battery year after year!

  • Even after 500 charges Max Capacity laptop batteries maintain ~ 70% of their charging capacities
  • Max Capacity 6 cell packs perform better then most 9 cell pack


Panasonics NNP technology helps prevent negative electrode deforming with repeated charging. This enables the new, lighter weight batteries to achieve the highest capacity in the market. Added to this is high cycle stability (a.k.a.Long Product Life) and excellent charging behavior as well as outstanding storage properties thanks to very low self-discharge.

Our combining of high quality parts results in an excellent overall performance over the whole life cycle of our laptop batteries. You won’t need to replace your Max Capacity laptop batteries as frequently as you have in the past. Typical Li-Ion replacement batteries only last about 300 full charges before needing another replacement. Max Capacity laptop batteries can achieve over 500 full charging cycles while still maintain very good performance!
