High Light 3.7V 300mAh polymer lithium battery11x30mm high discharge Li-Po cellPCB protected lithium battery with warranty
HZ11300 3.7V 300mAh Polymer Lithium Battery
Core Specifications & Product Features

The HZ11300 polymer lithium battery features compact dimensions of 11*30mm with a standard 3.7V voltage and 300mAh rated capacity. With a maximum charging voltage of 4.2V and discharge cut-off voltage of 3.0V, this battery maintains a stable factory shipping voltage of 3.8-4.1V to prevent self-damage during transit.

This high-performance battery supports a standard 0.2C continuous working current and an impressive 10C maximum continuous discharge rate, making it ideal for high-power instant output applications. It operates reliably across wide temperature ranges: 0℃ to 45℃ for charging and -20℃ to 60℃ for discharging, ensuring compatibility with both cold outdoor and warm indoor environments.

Customization services including OEM & ODM are fully supported, with free samples available for testing. The cell is certified with ISO9001 & ISO14001 quality and environmental management standards and comes with a comprehensive 12-month warranty.

Application Advantages

The compact 11*30mm slim size and 10C high discharge capability make the HZ11300 lithium polymer cell ideal for numerous portable mini electronic devices. It perfectly powers tiny wearable gadgets including smart bracelets, wireless Bluetooth earbuds, mini hearing aids, and portable health sensors.

Beyond wearables, this battery is suitable for small IoT equipment, mini remote controllers, wireless mice, tiny LED decorative lights, and compact portable medical testing tools. Its broad temperature tolerance enables reliable operation in outdoor mini monitoring sensors in low-temperature winter conditions as well as indoor small consumer electronics year-round.

Flexible OEM & ODM services allow customization of wire length, connector types, and PCB layouts to meet unique device design requirements for various industrial and consumer electronic manufacturers.

Safety Protection Features

The optional built-in PCB protection board provides four core safety mechanisms to eliminate battery hazards during daily operation:

  • Over-charge Protection: Automatically cuts off charging current when voltage exceeds 4.2V to prevent electrolyte expansion and swelling
  • Over-discharge Protection: Stops output when voltage drops to 3.0V, avoiding irreversible capacity loss
  • Short-circuit Protection: Triggers instant power cutoff when positive and negative poles accidentally contact, preventing high-temperature combustion risk
  • Over-temperature Protection: Monitors internal cell temperature in real time, disconnecting the circuit if abnormal heat accumulates

Combined with stable factory shipping voltage (3.8-4.1V), the cell avoids overcharged or damaged delivery status, significantly reducing safety risks during transportation, storage, and long-term standby.

Frequently Asked Questions
Can I get free samples of HZ11300 battery for testing?
Yes, we fully support free samples for quality and compatibility testing; buyers only need to cover the freight cost.
Is OEM and ODM customization acceptable for this cell?
Absolutely. We can customize leads, connectors, PCB circuits and package printing based on your technical drawings.
What is the valid warranty time of this polymer battery?
We provide a 12-month full warranty for all qualified HZ11300 cells under normal usage conditions.
What is the maximum continuous discharge rate this battery supports?
Its standard continuous working rate is 0.2C, and it can reach up to 10C for long-time high-power discharge.
What safety functions does the optional PCB protection board have?
It integrates over-charge, over-discharge, short-circuit and over-temperature four major protection functions to secure device use.
