Even if the part number looks right, battery outline, connector position, and screw-hole layout can still matter.<\/p>\n<p>Before ordering, check:<\/p>\n<ol>\n<li>Your exact laptop model<\/li>\n<li>Your original battery part number<\/li>\n<li>The battery shape and connector layout<\/li>\n<\/ol>\n<p>This is the safest way to avoid ordering the wrong battery.<\/p>\n<h2>Main Specifications of the HP RE03XL Battery<\/h2>\n<ul>\n<li><strong>Condition:<\/strong> Brand New<\/li>\n<li><strong>Color:<\/strong> Black<\/li>\n<li><strong>Capacity:<\/strong> 3750mAh \/ 45Wh<\/li>\n<li><strong>Voltage:<\/strong> 11.55V<\/li>\n<li><strong>Cells:<\/strong> 3 Cells<\/li>\n<li><strong>Package Includes:<\/strong> 1 x Battery for HP<\/li>\n<li><strong>Warranty:<\/strong> 12 Months \/ 30-Day Return<\/li>\n<\/ul>\n<h2>Who Is This Battery Best For?<\/h2>\n<p>The HP RE03XL battery is best suited to users who want to keep a compatible HP laptop in reliable daily use.
