Direct replacement for EliteBook 725 G3 and 820 G3

This 44WHR lithium-ion battery replaces the original SN03XL and 800514-001 packs. It fits HP EliteBook 725 G3 and EliteBook 820 G3 models. The three-cell design delivers 11.4V and 3859mAh capacity. It is a new GreenTech unit built to match OEM specifications.

Fits the existing battery bay without extra parts

The pack slides into the standard compartment on the supported EliteBooks. No adapter cables or firmware updates are required. It restores mobile operation when the original cell pack no longer holds charge. The unit is CE, FCC and RoHS certified for electrical safety.

44WHR capacity for typical office workloads

The 3859mAh rating supports several hours of document editing and web browsing on a full charge. Heavier tasks such as video playback or sustained CPU load will reduce runtime. The three-cell layout limits maximum capacity compared to larger six-cell options. Users needing all-day autonomy should consider a higher-capacity alternative if the chassis allows it.

Questions about this item

How long will the 44WHR capacity last under continuous load before the 3-cell lithium-ion pack hits its voltage floor?

The 3-cell lithium-ion pack rated at 44WHR and 3859mAh delivers runtime proportional to your EliteBook 725 G3 or 820 G3 power draw; heavier workloads deplete the 11.4V capacity faster.

Does the battery generate noticeable heat or fan noise during all-day operation in an EliteBook 725 G3?

The replacement battery itself has no moving parts and runs passively; any heat or fan activity comes from the laptop's own thermal management under load.

Which HP EliteBook models must I already own for this SN03XL 800514-001 battery to fit and function?

This GreenTech SN03XL unit is designed for HP EliteBook 725 G3 and EliteBook 820 G3 laptops that originally used part numbers SN03XL, 800514-001, SN03044XL-PL, HSTNN-DB6V or T7B33AA.
