HP EliteBook 840 Laptop Battery: what you should know

Written by the Siri Technofab technical team — the same people who fit these batteries every week. Last reviewed on 9 July 2026.

India's default corporate laptop, kept alive

EliteBook 840s arrive in our workshop daily — the platform is excellent, and a tired battery is usually the only thing wrong with a 4–5 year old unit. A new battery typically takes runtime from under an hour back to a full working session.

Generation matters

HP changed the battery design across 840 generations, so 'EliteBook 840' alone isn't enough to pick a part. We match by your product number before dispatch, which is why our return rate on these is effectively zero.

How to order the right battery

Battery fitment depends on the exact battery part number, not just the laptop model — the same laptop line can ship with different batteries. Send us a photo of your current battery label (or your laptop's service tag) on WhatsApp and we'll confirm the exact match before you pay. Fitting guidance is included with every order, and we can arrange installation support if you need it.
