GreenTechLLC FZ-VZSU88U 10.8V 94WHR 9-cell laptop battery

GreenTech 9-cell 10.8 V replacement battery

The GreenTech FZ-VZSU88U is a 9-cell lithium-ion pack rated at 10.8 V and 94 Wh. It is built as a direct replacement for the original Panasonic Toughpad FZ-G1 battery across every listed MK1 through MK5 variant and associated sub-models. Field technicians and mobile workers who rely on a single rugged tablet for full-day shifts receive a new, tested unit with CE, FCC and RoHS safety certification. ||

Upgrading from the standard-capacity pack

The original equipment battery supplied with many FZ-G1 units offers lower watt-hour capacity. Moving to this 94 Wh extended cell adds meaningful runtime for users who regularly operate away from mains power, such as survey crews, logistics staff or emergency responders. The jump is worth it when a single charge must cover an entire shift without access to a charger or spare pack. ||

Sustained discharge under field conditions

The 9-cell chemistry delivers stable voltage across long discharge cycles rather than only in short bursts. Rigorous pre-shipment testing confirms correct voltage regulation, circuit protection and low self-discharge, so the pack maintains usable capacity after weeks of intermittent use. Heavy GPS, barcode or cellular workloads draw steady current without the voltage sag seen in aged or lower-capacity cells.
