ZTHY AP19D5P Replacement Battery 74Wh 15.4V for Acer

ZTHY AP19D5P is a direct-fit 74Wh, 15.4V lithium-ion replacement battery engineered to restore runtime for select Acer ConceptD 3 Ezel and Predator Helios 500/700 laptops.

If your Acer laptop no longer holds charge or shuts down unexpectedly, a fresh battery designed for the original connector and voltage can bring performance back without replacing the whole machine. The ZTHY AP19D5P is a new-from-manufacturer Li-ion pack rated 74Wh / 4660mAh and finished in black. It’s built to match AP19D5P and CS-ACP315NB part numbers and supports a broad set of Acer model variants—double-check your laptop’s battery sticker to confirm exact compatibility before ordering.

Which Acer models will this ZTHY battery work in?

This battery is compatible with many ConceptD 3 and Predator Helios series models that use the AP19D5P form factor and 15.4V electrical specification. It covers multiple CN315 and CC315/CC314 ConceptD 3 Ezel family SKUs and a wide range of Predator Helios 500 and 700 model variants. Always match the part number printed on your old battery rather than relying solely on laptop model names.

• Fits ConceptD 3 CN315 and Ezel CC314/CC315 series variants listed by model suffix
• Supports Predator Helios 500 PH517-52 series and Helios 700 PH717-72 series
• Cross-referenced with AP19D5P and CS-ACP315NB replacement part numbers

How much runtime and power does this replacement provide?

The AP19D5P pack delivers 74 watt-hours at 15.4 volts, which restores the original power envelope expected for these laptops. Actual runtime depends on your workload—video editing or gaming will draw far more power than web browsing. Using power-saving settings and updating drivers can help maximize the battery’s usable life.

• Rated capacity: 74Wh (4660mAh)
• Voltage: 15.4V, compatible with OEM charging circuits
• Performance varies by application, display brightness, and CPU/GPU load

What should I know about installation and first-use steps?

Install the battery only after powering down and unplugging the laptop. If the system doesn’t immediately recognize the new pack, verify the connector is fully seated and reinstall if necessary. It’s normal to condition a new Li-ion battery: discharge to around 10–20% (avoid full 0%) and then recharge fully for several cycles to help the battery management system calibrate.

• Power off laptop and unplug before replacing the battery
• Reseat connector if the battery isn’t recognized on first install
• Cycle 3–4 charge/discharge events between ~10–100% to optimize detection

Are there compatibility risks I should avoid?

Acer models often share similar battery shapes and connectors, which can make selecting the right pack confusing. A physically fitting battery can still be electrically incompatible or fail to communicate properly with the laptop. For reliable operation, confirm the part number on the original battery and compare voltages and connector type before purchase.

• Verify original battery part number (AP19D5P or CS-ACP315NB)
• Compare nominal voltage (15.4V) and physical connector layout
• Avoid assuming fit based only on laptop model name—check sticker details

Who is this battery for? The ZTHY AP19D5P is aimed at users with compatible Acer ConceptD 3 Ezel and Predator Helios 500/700 laptops who need to replace a worn-out or failing battery without changing their system. It suits creative professionals, gamers, and power users who require OEM-equivalent voltage and capacity and who can confirm the correct part number. If you need longer runtime or different voltages, review alternate battery options or contact support to verify fit before ordering.
