HP SS03XL Replacement Battery Review
HP SS03XL replacement battery (HP spare 933321-855): the 11.55V 50Wh 3 cell pack for the HP EliteBook 830, 840, 735 and 745 G5 and G6.
HP's QuickSpecs list a 3 cell 50Wh Long Life battery for the EliteBook 840 G5 and 840 G6, which matches the SS03XL rating, and iFixit sells the SS03XL for the 830, 735 and 745 G5. Our data adds the G6 versions of those three. The pack is internal, so the bottom cover has to come off. Check your old label for SS03XL, 933321-855 or 932823-421. The capacity figure on our record is a seller claim that matches HP's QuickSpecs.

Safety and handling
A swollen pack means stop using the device now. Do not charge it, press on it, puncture it or pry at it with metal tools, and keep it out of water and household waste.
New packs ship at partial charge, around 30 percent, because air transport rules for lithium ion batteries require it. A pack that arrives low is correct, not faulty. Charge it fully before you judge it.
Recycle the old pack at an electronics or battery drop-off point. Never mail it back.
Age and condition
Lithium ion loses capacity on the shelf. Battery University's storage figures show roughly 96 percent retained after a year at 25C and 40 percent charge, against about 80 percent for a pack stored full. A pack that sat in a warehouse for years can arrive tired.
None of the listings we checked for this pack state a manufacture date code, so check the date printed on the label when it arrives. On HP machines a tired old stock pack can trigger the Primary (internal) Battery (601) alert on first boot, so a 601 on day one is a reason to return it.
If this is not yours
If the label on your old pack does not read SS03XL, this page is not your answer. Use our battery finder at /laptop-batteries and search by your laptop's exact model number or by the code printed on the old pack.

FAQs
Can I fit a higher capacity pack in my EliteBook 840 G5?
We have found no HP listing for a larger pack in the 840 G5 or G6. The 50Wh SS03XL is the one HP lists.
Why does my laptop say the battery is not genuine?
HP firmware measures rather than authenticates. The Primary (internal) Battery (601) alert fires when measured capacity or the self test falls below HP's threshold, which an aged new old stock pack can do on first boot. So a 601 on a fresh SS03XL usually points to a tired pack, not a fake one. Ask the seller for a replacement with a recent date code.
Why did my new SS03XL arrive at 30 percent?
Because it has to. IATA rules in force since 1 January 2026 require lithium ion batteries like this 50Wh pack to travel by air at no more than 30 percent of rated capacity. A low pack on arrival is correct. Charge it to full in the laptop and run it through a normal cycle before deciding anything about its health.
