Power Cells

Dendy: You know how it is with power cells. [Laughs]K.O.: [Laughs] Yeah! Power cells! That’s like a battery? 
Dendy: Precisely! It’s the last thing I need to restore the backpack to its former glory. Once we retrieve one, that’ll be it!
:--OK KO, "I Am Dendy"
Power cells are GURPS' name for portable ultratech energy storage devices, similar to real-world batteries. They have a variety of sizes, used for different purposes.
== Power Cell Sizes ==
From Ultra-Tech.Ultra-Tech, p.19
Size	Description 	Weight
AA 	Tiny cells, weighing less than a gram. These are used in tiny robots and some implants. 	0.0005
A 	Small cells, about the size of a postage stamp, but thicker. They're used in consumer goods like clothes. Flexible variants are used in smart clothing. 	0.005
B 	B cells are the most common for small tools, like flashlights, cell phones, professional cameras, and so on. Medium tools--like plasma torches and such--use C cells instead. 	0.05
C 	C cells are the most common cell for medium-sized tools--and weapons. Ultratech battlefields tend to be littered with empty C cells. Most heavier gadgets--anything about 5 lbs or more--tend to use a C cell as a backup when not plugged into a wall. C cells power most forms of portable scanning devices. 	0.5
D 	These weigh about 5 lbs each and are about the size of a thick paperback book. They tend to be used in semi-portable devices--such as heavy scanning equipment, long-range communicators, and heavy support weapons. These hefty cells provide the beating hearts of androids and human-sized robots--doubled or tripled-up if the robot is particularly powerful.	5
E 	Backpack-sized power cells used for heavy, specialized tools--or small vehicles and exoskeletons! These can provide power to small shelters, effectively running several smaller devices and keeping the lights on. The largest power cell sold in factory-outlet stores--for F cells, you'll need a specialist. 	20
F 	Size of a small engine, and about the weight of an adult human. These can power medium to large vehicles, or cannon-sized beam weapons. In Ultra-Tech, they are used exclusively in vehicles, such as the grav jeep. 	200
== Flexible Power Cells ==
Flat polymer cells, used for powering electronic clothes, printed computers, or even vacc-suits. AA and A cells are the same cost, others are 4x the normal cost.
== Cosmic Power Cells ==
"Each cube contains the equivalent ionic energy of 5 kilotons of TNT" ''
:-- Ion Cube databank entry, Subnautica
Cosmic power cells are a TL12^ invention, and often only seen in the ruins of fallen hypertech societies--or very lucky adventurers. Cosmic power cells retain their charge indefinitely, and their only limitation seems to be their inherent size. It may be possible to connect multiple, smaller cosmic cells to power a much larger device, but this may require some very high skills or a particular talent to do so.
== Optional: Power Cells Exploding ==
Power cells can be volatile when damaged! Treat these as an explosive of the same weight as the cell, but with REF varying on Tech Level:
TL 	REF 	C Cell
(0.5 lbs) 	D Cell
(5 lbs)
9 	0.125 	3d 	9d
10 	0.5 	6d 	3dx6
11 	2 	x4 	x4
12 	4 	x4 more 	x4 more
Cosmic	5,000Cosmic cells are very, very powerful	Oh no6dx100. This is more damage than a 500-lb Mark 82 bomb!	OH NOAbout 6dx300 damage. Still not a nuke, but quite a huge amount of damage.
