High-Temperature Lithium Battery

The best choice for powerful, quick-charging and consistent power sources is lithium batteries. The temperature range of a high-temperature lithium battery is a wide 40°C to +125°C (-40°F to +257°F).

Its charge and discharge temperatures are -20°C to 60°C and -40°C to 85°, respectively. In demanding applications, they, therefore, guarantee security, high energy, and great reliability.

Extensive Features

We produce high-temperature lithium batteries here at ThinPack using 18650 lithium cells. This cell technology has the ability to charge at high temperatures safely and for an extended period of time. ThinPack can serve your OEM/ODM requirement as a dependable provider.

The size of a high-temp lithium battery can be altered to fit different cylinders and prismatic shapes. If you need a DD cell size with M8 terminals, a variety of alternate hard case cell sizes can be provided. 

High voltage – 3.6 to 3.9 V per cell and its sturdy, pressure-resistant stainless steel container are the two most prominent characteristics of Thinpack’s batteries for high temperatures.

Since Thinpack places a high priority on their customers’ safety, safety features including shock and vibration resistance are included.

These batteries can store a lot of energy in a relatively small mass because of their high energy density! 

Other characteristics are:

    • pulse discharged quickly
    • very low rate of self-discharge
    • Hermetic glass-to-metal sealing that complies with IAF16949 standards
    • a powerful and dependable working voltage
    • Exceptionally safe, sturdy, and stable up to 150 °C


Our range of high-temperature lithium batteries is used in broad applications including;

  • ATM machine
  • Memory backup
  • Military projects
  • Power tools
  • Measure While Drilling
  • Alarm and security systems
  • GPS for trucks or containers
  • Tollway transponders and RFID.
  • Handheld industrial scanners, etc.

Advantages of High Temp Lithium Battery

These batteries have a few advantages that make them so loved globally in many fields which are:

  1. Continual temperature stability: lasts longer and can store six times as much energy than regular lithium batteries
  2. Portability: This form of the battery can supply the energy required to heat many types of structures, whether it is a modest apartment, a villa, or the reality of a huge industrial or tertiary company and withstand heat as well.
  3. Long life cycle: These systems can survive up to several years due to materials’ resilience to higher temperatures.


Particularly in automobiles and solar generators, lithium-ion batteries have emerged as the preferred source of high-powered, long-lasting energy. 

But if you intend to use them in frequently warm conditions, you should give the matter some more thought. The majority of hot places don’t pose a concern, but placing them in a really hot room or close to an engine could cause them to degrade.

Batteries produced by Thinpack can endure temperatures up to 130. But since temperatures could be an issue for all batteries either way, the manufacturers at Thinpack suggest that it is best to maintain their temperatures under control.



How many charge cycles can a high-temp lithium-ion battery offer?

No matter how powerful a rechargeable battery is, it can only be used in a limited charge cycle. High-temp lithium-ion batteries can be fully charged 500–2000 times before they need to be replaced.

How long does it take to charge?

A high-temperature lithium-ion battery typically charges fully in 3–4 hours. It needs to be partially charged to have a longer lifespan. Avoid overcharging the battery and never let it go to 20% or less before recharging.

Can a battery be harmed by heat?

The battery’s lifespan is shortened by hot weather.

What to consider in buying a high-temperature lithium-ion battery?

Depending on what it will be used for, the battery should be chosen. Before buying you need to consider the following:

  • amps
  • mAh
  • capacity
