VRD Solution

features:

1. Voltage: Most portable thermal printers use batteries ranging from 7.4V to 12V, but you should check your printer’s manual to confirm the required voltage.
2. Capacity: The battery capacity is typically measured in mAh (milliampere-hours). Higher mAh means longer battery life. For example, a battery with a 2500mAh or 3000mAh rating might last for a full day of printing under moderate use.
3. Battery Life: Battery life varies depending on the print job. Printing at a high speed (120 mm/sec) uses more power, so consider this when selecting a battery.
