Replacement battery for Acer Predator

This 15.4V lithium-ion pack replaces the original AP18E7M or AP18E8M unit in compatible Predator Helios 300, Triton 300, Nitro 5, Nitro 7 and Aspire 7 models. It delivers a rated capacity of 3815mAh (58.75Wh) across four cells and ships with two screwdrivers to simplify the swap.

Steady output during long sessions

The 4-cell lithium-ion chemistry maintains a stable 15.4V rail under continuous load, so the laptop can sustain performance during extended gaming or rendering without the voltage sag that worn packs exhibit. Capacity is specified at 3815mAh, giving a predictable runtime baseline for work or play away from mains power.

Verify the exact model code before ordering

Check the part number printed on your existing battery — it must read AP18E7M, AP18E8M, 4ICP4/69/90, 4ICP4/70/88 or KT.00407.009 — and confirm the laptop series appears in the supported list such as PH315-52, PH315-53, PH317-53, PT315-51, AN515-54, AN515-43, AN517-51, AN517-52 or AN715-51. The pack is not suitable for laptops that require a different voltage, cell count or connector layout.

Questions about this item

Does the 15.4V 3815mAh lithium-ion pack generate noticeable heat or noise during all-day use?

The battery is a passive 4-cell lithium-ion unit with no moving parts, so it produces no audible noise. Normal warmth may occur under heavy load, but it does not actively generate heat beyond typical discharge.

What must already be in the laptop for this AP18E7M battery to work?

The laptop must be one of the listed Acer Predator Helios 300, Predator Triton 300, Nitro 5, Nitro 7, Aspire 7 or ConceptD models and use the original 15.4V 4-cell battery connector. Two screwdrivers are included for installation.

Will the AP18E7M fit alongside the original cooling assembly and chassis screws in a PH315-53?

Yes. The pack matches the factory 4-cell form factor and voltage, so it seats in the same bay, uses the existing screw points and clears the stock heatsink and fan assembly without modification.
