Upgrade LK-72 Battery Pack 3500mAh 10.8V for PIXMA TR150 - Extended

In this review of the Upgrade LK-72 Battery Pack, the bottom line is simple: it gives PIXMA TR150 owners a practical, high-capacity backup power option for printing on the go. The reviewer found the LK-72 best for people who routinely use the PIXMA TR150 away from AC outlets and need extra runtime without carrying the original charger. The most persuasive reason to buy is the larger 10.8V / 3500mAh capacity that extends mobile printing sessions significantly while remaining lightweight and easy to install.

Key Features

• Exclusive Replacement Battery: Designed specifically for the PIXMA TR150, the LK-72 matches the original battery case fit so it attaches cleanly to the printer without modification.
• Upgraded Capacity: The 10.8V / 3500mAh Li-ion cells deliver much longer runtime than the factory spare, making it useful as a true backup for extended travel or field work.
• USB-C Charging: The added USB-C charging option allows topping up from a power bank, laptop, or car charger when the original AC adapter is not available.
• Lightweight & Portable: The battery remains compact and easy to carry, enabling the PIXMA TR150 to remain a genuinely portable printer without adding bulk.
• Easy Installation: It installs using the original battery cover (not included) and requires no tools, so swapping batteries is straightforward in the field.

Who It's For

The LK-72 battery is aimed at PIXMA TR150 owners who frequently print while traveling, at trade shows, or in vehicles and need extended runtime without an AC outlet. Photographers, mobile sales professionals, and small-business users who rely on uninterrupted portable printing will appreciate the larger 3500mAh capacity and USB-C charging flexibility.

It is not for users who expect to charge and use the printer simultaneously, since the battery cannot be used while charging, or for people who need the printer's back cover supplied; the product is the battery only and requires the original back cover for attachment.

Cons

• Back cover is not included, so users must have the original cover to attach this battery.
