Compatible HP EliteBook battery

The Cameron Sino DS-CS-HPE745NB is a new lithium-polymer replacement battery rated at 3.4 Ah. It fits HP EliteBook 745 G3, 755 G3 and 840 G3 models. The unit replaces original part numbers such as 800513-001, CS03XL, HSTNN-IB6Y and T7B32AA. Black finish matches the original chassis.

For owners of listed EliteBooks

This battery suits users who need a direct replacement for the specific EliteBook 745 G3, 755 G3 or 840 G3 series. It is not for owners of other HP laptop families, newer EliteBook generations or devices that require a different voltage or connector layout. Buyers needing higher capacity than 3.4 Ah should look elsewhere.

Capacity decides fit

The single specification that confirms compatibility is the 3.4 Ah rating combined with the exact model list. Verify your laptop model number against the supported EliteBook 745 G3, 755 G3 and 840 G3 variants before purchase. Only that match guarantees correct fit and function.

Questions about this item

How long does the 3.4 Ah Li-Polymer battery last before it needs replacing?

The 3.4 Ah Li-Polymer pack is rated for typical daily cycling; most users replace it once run-time falls below their needs, usually after a few years of regular charge cycles.

What limits run-time first during a full-day workload on the DS-CS-HPE745NB?

The 3.4 Ah capacity sets the hard ceiling; sustained heavy loads will drain the pack faster than light use, so the amp-hour rating is the first limit you hit.

Does the battery get hot or noisy when the EliteBook 840 G3 runs all day?

The pack has no moving parts and generates only modest warmth during normal discharge; it stays silent and within safe temperature limits for the 745, 755 and 840 G3 series.
