Twinhead SlimNote Battery model is over 3 years old and Li-Ion Cells have a maximum 3 year shelf life.   This means you are not getting 100% battery capacity even if it is new and sealed in the box.

There's a quick and simple solution to revive that depleted battery of yours.   Try our laptop battery refill service!   All you have to do is mail your old battery to us with the Pre-Paid-Postage-Label (US customers only) we email to you after you place your order.   We will then mail back the refilled battery that will contain longer running new battery cells.

NOTE: Even if your laptop battery is completely dead, you may still send it to our facility for a refill service.   There is a high possibility (over 95%) that your battery can be repaired & refilled to a new super-capacity battery .

If we are unable to refill the battery, we will send you back your battery pack and credit you a full refund, including shipping. (Applicable to this battery model only). So, with nothing to lose, why not try our battery refill service today!!

When the battery is all done, we will send you a 100% tested Genuine Twinhead Refilled Battery to ensure that it will equal or exceed your original battery's life.   Every battery comes with a 1 Year Warranty!
