Renew your Acer power with the TAVZENL AP18C4K battery

The TAVZENL AP18C4K battery is a 48Wh, 11.4V rechargeable replacement designed for select Acer laptops. Brand-new, in black, and manufactured to fit snugly inside your device, it aims to restore reliable power when you need it most.

With an approximate capacity of 4200 mAh, this pack is built to support daily tasks and leisure activities, from document editing to streaming, by delivering steady power through typical sessions.

What to expect in everyday use

In real-life scenarios, you may notice longer intervals between charges for common tasks such as web browsing, office work, media playback, and light multitasking. The AP18C4K aims to maintain power consistency and smooth operation as you move through your day.
