Questions about this item

How many full charge cycles can the 45 Wh RE03XL pack deliver before capacity drops off?

The manufacturer rates the grade-A lithium-polymer cells for hundreds of cycles; capacity fade becomes noticeable after extended daily use, so plan on one replacement during the laptop's service life.

What runtime limit appears first when the 3750 mAh battery runs a ProBook 450 G6 at full load?

The 45 Wh capacity is the limiting factor; sustained heavy workloads drain the pack in a few hours, so the energy rating rather than voltage or current ceiling caps usable time.

Does the 11.5 V RE03XL run hot or draw extra power during all-day operation?

The built-in microchip prevents over-charging, over-discharging and over-heating, keeping temperature and power draw within normal limits for a 45 Wh lithium-polymer pack.
