Compatible replacement for ASUS ROG G751 series

This 15V 88Wh lithium-ion battery replaces part numbers A42N1403, A42LM93 and 4ICR19/66-2. It fits ROG G751, G751J, G751JL, G751JM, G751JY, G751JT, GFX71 and ROG GFX71 series laptops. The black pack restores mobile power for supported 17.3 inch models.

Thermal and power behaviour in normal use

The lithium-ion chemistry delivers steady 15V output during typical workloads. Internal resistance remains low at room temperature, so the pack runs cool during office tasks or media playback. No active cooling is required inside the laptop chassis.

Sustained-load performance

Under continuous high draw the cell voltage holds stable until the 88Wh capacity is depleted. The pack does not throttle output early, but runtime shortens proportionally to load. It is not suited for users who need hot-swap capability or extended runtime beyond the rated capacity.

Questions about this item

How do I install the A42N1403 battery in my ASUS ROG G751 series laptop, and what step do people often miss?

Power off the laptop and disconnect the AC adapter. Remove the bottom panel screws, unplug the old battery connector, fit the new 15V 88Wh pack, reconnect the cable firmly, then replace the panel before powering on.

What maintenance or replacement will the 4ICR19/66-2 lithium-ion pack need over time?

The 88Wh lithium-ion cells gradually lose capacity; expect to replace the pack when run-time drops below your needs, typically after several hundred charge cycles.

What limit appears first during sustained heavy use on this 15V 88Wh battery?

The 88Wh capacity sets the runtime ceiling; under continuous high load the pack will deplete faster and voltage will sag until the laptop shuts down.
