'''Batteries''' are used as a means of supplying power to devices, such as the HEV Suit|HEV suit, the Powered Combat Vest, various Combine technology, and many other things. Throughout the ''Half-Life'' series, they can be found throughout the Black Mesa Research Facility, and are normally located throughout built-up areas and Resistance bases. 


===''Half-Life'' and its expansions===

Throughout Black Mesa Research Facility|Black Mesa, batteries can be found almost everywhere. They were notably used by Gordon Freeman and other Black Mesa scientists to charge the HEV suits. They were also used by Adrian Shephard (as well as other members of the HECU) to charge up the Powered Combat Vests.  It would seem that, due to their abundance, they were used for more than just this, though.

Batteries give the player a different amount of armor points depending on the difficulty mode. In easy and medium modes, batteries give the player 15 armor, while in hard mode, batteries only give 10. This means that the player will have to rely on Chargers for a large increase in armor points.

====Behind the scenes====
The ''Half-Life'' demo (''Half-Life Day One'') features a different model. It is also used as a temporary model for the Long Jump Module, with red panels instead of blue.

There is a high-definition battery texture in the Half-Life SDK|''Half-Life'' SDK, however it is never used in any official games and possibly used as a source for the final texture.

===''Half-Life 2'' and Episodes===

In ''Half-Life 2'', the new, redesigned batteries serve more purposes than simply charging the HEV suit; they are also used as a portable power source for several Combine devices, most notably the City Scanner. To accommodate the new Combine batteries, the Mark V HEV suit was redesigned by Isaac Kleiner to be able to utilize them. Batteries will give the player 15 Armor Points, regardless of difficulty mode. This means that the player will still need to depend on HEV Chargers to obtain a large amount of Armor Points.

====Behind the scenes====
Unused sound clips from the playable Half-Life 2 Beta|''Half-Life 2'' Beta indicate that Batteries could be charged up at one time, though how this was done is unknown. In the Beta, the Battery model is exactly like the one in ''Half-Life'', only much smaller.

During the beginning of Half-Life 2 in the map  ''d1_trainstation_04'' it is possible to destroy a City Scanner by simply throwing cans at it; giving you a battery before you even obtain the HEV suit.http// City Scanner glitch discovered by Matmo

The battery can only be charged to 100, so if HEV Suit is powered with Dark Energy, the battery can only charge the suit power up to 100. this can also be seen without the use of the console; in order to do so, you'll have to destroy a City Scanner located in the Citadel.

During the ambush of White Forest Inn, if an Overwatch Elite|Elite Soldier is killed, he will drop a Battery instead of an Energy Ball. This is most likely a balancing reason, as they are very efficient against Hunters.

===''Deathmatch Classic''===

In ''Deathmatch Classic'', the Battery is used as ammo for the Lightning Gun. A small Battery gives the player 6 cells, while a large Battery give the player 12 cells. However, both small and large batteries use the same model.
