Gateway 400SD4 models are 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.

When the battery is all done, we will send you a 100% tested Genuine Gateway 400SD4 Refilled 6600mAh Battery. Every battery comes with a 1 Year Warranty !!!

There is a high possibility (over 95%) that your battery can be repaired & refilled to a new super-capacity battery even if it is completely dead.

NOTE: If your battery is completely dead, you may still send it to our facility for refill service. 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 refill program today!!

The battery capacity increases every few months and 400SD4 battery packs have 1900mAh capacity Sanyo Li-Ion cells. The new cells we are using to replace your batteries are 2200mAh LG Chemistry Cells. As a result of the refill service, a 5700mAh capacity Li-Ion battery pack increases to 6600 mAh capacity.

This means longer run-time (20% higher capacity) compared to the original without causing any incompatibilities.
