HP SS03XL Replacement Battery Review
HP SS03XL replacement battery (spare 933321-855), the 11.55V 50Wh pack for the HP EliteBook 840 G5 and 840 G6, plus the 830, 735 and 745 G5 and G6.
HP's QuickSpecs list an HP Long Life 3-cell 50Wh battery for both the 840 G5 and 840 G6, which matches the SS03XL rating. It is internal, so the bottom cover has to come off to swap it.
How to confirm the fit
Check the label on your old battery for SS03XL, 933321-855 or 932823-421. On the laptop, the model name sits on the bottom cover or in the BIOS.
