GMCELL AA 2500 USB Rechargeable Batteries

About this :

* Low self-discharge – GMCELL AA batteries will remain 90% juice when you leaving it for no use 1 year
* Safer AA Battery – Embedded seal structure, ultra slim and make more inner space, DBCK steel shell can protect the battery against explosion due to overpressure.
* High Quality – Rechargeable Lithium battery, no memory effect, can be charged and used at anytime.
* Super Capacity – 600~2500 mWh AA/AAA rechargeable batteries, the highest on Amazon.com, high performance and long lasting for daily household devices
* Supercell lattice - GMCELL batteries made in supercell lattice technology, make it more inner space to contain such high volume power juice, provide constant voltage and best performance in heavy load discharge.
