ASP Best Premium CR-123A Lithium Battery 03028 packaged in 12 cell boxes. Quality Lithium Batteries with a 10 year shelf life and PTC protection. These Batteries are excellent for all professionally used equipment including photography, camera, flashlights, lasers, headlamps, radios and much more.

ASP Batteries incorporate two safety devices not found in some other CR-123A Batteries. The first is a resettable current and thermal protection system which protects devices from damage if the discharge current rises above the design limits. Using PTC Technology ASP CR123A Batteries offer safety and protection for the user. Another safety device is a pressure relief which prevents the cell body from rupturing due to excessive pressure, heat or mechanical abuse. Vent holes are incorporated and are designed to activate in the presence of dangerous pressures

    More about PTC Protection

    Thermistors are circuit devices whose resistance varies with temperature. PTC thermistors have a Positive Temperature Coefficient in that their resistance increases gradually with temperature and over a limited range the resistance can be considered linearly proportional to temperature. Similarly NTC thermistors have a Negative Temperature Coefficient and their resistance decreases as temperature increases. These components are used extensively in monitoring and protection circuits to provide a voltage analogue of temperature or in control circuits designed to provide temperature compensation. They may be used to terminate the charge (dt/dT) or to disconnect the battery from the charger in an over-temperature condition when the temperature cut off point is reached, or they could be used to turn on cooling fans. In some applications the thermistor may be the only means of communication between the battery and the external world.

    Thermistors can also be used by the charger to determine starting environmental conditions and prevent charging if the battery temperature is too low or too high.

    Resettable Fuse

    A resettable fuse provides on-battery over-current protection. It has a similar function to a thermal fuse but after opening it will reset once the fault conditions have been removed and after it has cooled down again to its normal state. It requires no manual resetting or replacement and so is very convenient for the user who may not even be aware of its operation.

    The fuse is triggered when a particular temperature is reached. The temperature rise can be caused by the resistive self heating of the thermistor due to the current passing through it, or by conduction or convection from the ambient environment. Thus it can be used to protect against both over- current and over-temperature.

    Also called a PPTC (Polymeric Positive Temperature Coefficient) device, the resettable fuse is a non-linear PTC thermistor based on a thin composite of semi crystalline polymer and conductive particles. Under normal operating conditions, the conductive particles provide a low resistance path allowing current to flow. Under fault conditions that cause excessive temperature, such as excessive current flow or an excessively high ambient temperature, the crystallites in the polymer undergo an abrupt phase change within a very narrow temperature range melting and becoming amorphous causing separation of the particles resulting in a large, non-linear increase in resistance.

    The sharp increase in resistance is typically three orders of magnitude or more, reducing the current to a relatively low and safe level. It will hold in this high resistance state until the fault conditions are removed. On cooling the phase change is reversed and the PPTC resets to low resistance state (within certain post trip limits).

    Devices have a de-rating at elevated temperatures which means that they will trip at a lower current if the temperature is higher.
