There are four different attributes that affect the life expectancy of a crystal. These attributes function identically for both combat and mining crystals.

Some combat crystals have a 100% chance of damage per shot.  It also means that the life expectancy of these combat crystals may be calculated exactly, because every shot will always damage the crystal.  (Currently, all faction combat crystals have a 100% Volatility, i.e. a 100% chance of crystal damage inflicted per shot.)

=== Activation Cycles ===
In terms of Volatility, an Activation Cycle is a single cycled use of a laser crystal by the turret within which it is loaded. With combat crystals, each time the energy weapon is fired is considered one cycle.
With mining crystals, a cycle may begin with the activation of the mining laser and may end with either the deactivation of the laser or the acquisition of materials (ore or ice). This means that a cycle is completed even if a mining laser is turned off early. Repeatedly turning a mining laser on and off will risk damaging the crystal whether or not any actual materials were mined.

Currently, the only crystals in the game whose Crystals Take Damage value is False are the Tech-1 combat crystals. These will never take damage and thus they may be used indefinitely. Note that if the value of this attribute is False, then it will not even be listed in the Attributes tab of the Show Info window.

The formula for determining average life expectancy of a crystal is simple:
The formula for determining average life expectancy of a crystal is simple:
 
:<math>\text{Life Expectancy (in cycles)} = \text{Structure Hitpoints} / \text{Volatility} / \text{Volatility Damage}</math>
:<code>Life Expectancy (in cycles) = Structure Hitpoints / Volatility / Volatility Damage</code>


One may then multiply the expected cycles by the cycle time to calculate a crystal's life expectancy over time.  Remember that Volatility is a percentage, so for example, a crystal with a Volatility of 10% must use the value 0.10 in the equation.

== Examples ==
The Simple Asteroid Mining Crystal Type A I has a Volatility of 10%, which means that for every cycle there is a 10% chance that it will receive damage. The amount of damage it receives will be the Volatility Damage value of 0.05 HP. It will shatter when its total damage reaches the Structure Hitpoints value of 1 HP.


The Plagioclase Mining Crystal I has a Volatility of 10%, which means that for every cycle there is a 10% chance that it will receive damage. The amount of damage it receives will be the Volatility Damage value of 0.025 HP. It will shatter when its total damage reaches the Structure Hitpoints value of 1 HP.  
This means that, on the average, the crystal has a life expectancy of <math>1 / 0.10 / 0.05 = 200</math> cycles.  With a standard (unbonused) strip mining cycle time of 180 seconds, one may estimate that a crystal will endure approximately 36,000 seconds, or 10 hours, of constant mining before shattering.


This means that, on the average, the crystal has a life expectancy of <math>1 / 0.10 / 0.025 = 400</math> cycles. With a standard (unbonused) strip mining cycle time of 180 seconds, one may estimate that a crystal will endure approximately 72,000 seconds, or 20 hours, of constant mining before shattering.
The Simple Asteroid Mining Crystal Type A II has a Volatility of 12%. It has the same 0.05 HP Volatility Damage, and 1 HP Structure Hitpoints as the tech I variant. As a result, the crystal has a life expectancy of <math>1 / 0.12 / 0.05 = 166</math> cycles. However, a ship using these crystals will likely not be operating unbonused; it will likely be flying with significant improvements to its mining cycle time. So, while an unbonused strip miner cycle takes 180 seconds and a tech II would last around 8 hours, strip miners fitted to a max-skilled [[Hulk]], enhanced by a Mining Laser Optimization Charge from a [[Rorqual]], can cycle in as little as 42 seconds, thus reducing the crystals lifespan to a mere 116 minutes. <!--edit break-->However, to compensate, if further enhanced by an Equipment Preservation charge, the crystals volatility can be reduced by up to 60%, resulting in a new life expectancy of <math>1 / 0.08 / 0.05 = 500</math> cycles, which at 42 seconds per cycle comes out to 21,000 seconds, or just short of 6 hours of constant mining before shattering.


The Plagioclase Mining Crystal II has a Volatility of 20%. It has the same 0.025 HP Volatility Damage, and 1 HP Structure Hitpoints as the tech I variant. As a result, the crystal has a life expectancy of 1 / 0.20 / 0.025 = 200 cycles. However, a ship using these crystals will likely not be operating unbonused; it will likely be flying with significant improvements to its mining cycle time. So, while an unbonused strip miner cycle takes 180 seconds and a tech II would last around 10 hours, strip miners fitted to a max-skilled [[Hulk]], enhanced by a Mining Laser Optimization Charge from a [[Rorqual]], can cycle in as little as 42 seconds, thus reducing the crystals lifespan to a mere 138 minutes. However, to compensate, if further enhanced by an Equipment Preservation charge, the crystals volatility can be reduced by up to 60%, resulting in a new life expectancy of 1 / 0.08 / 0.025 = 500 cycles, which at 42 seconds per cycle comes out to 21,000 seconds, or just short of 6 hours of constant mining before shattering.
