As a manufacturer, Green Cell has always strived for excellence. As a result, they have created the PRO and ULTRA laptop battery categories. These models have higher performance and longer battery life than their counterparts.
PRO batteries. Samsung SDI cells provide the higher performance and longer battery life in these batteries.
ULTRA batteries: Thanks to premium quality Panasonic cells, these batteries can provide up to 2x longer battery life than factory batteries.
Both ranges are perfect for those who like maximum performance and rarely need to charge their laptop.
