Zyudenchi

The Zyudenchi (獣電池) are special battery-like devices powered by an energy source known as Brave (ブレイブ), which hold the Kyoryu Spirit (キョウリュウスピリット) of what prehistoric animal the Zyudenchi represent. To activate them, a Kyoryuger announces "Brave In" (ブレイブイン) and presses down on a little button on the negative side of the Battery, activating the Brave charge.

The Zyudenchi from #1 to 10 hold the Kyoryu Spirits of the Ten Great Zyudenryu (十大獣電竜) and can summon the respective mecha, which sealed the Deboth Army, while Zyudenchi #00 holds the Kyoryu Spirit of Zyudenryu Tobaspino (獣電竜零号 トバスピノ) who is the predecessor to the other Zyudenryu, and the rest of the numbered Zyudenchi hold the Kyoryu Spirits of the Guardians (ガーディアンズ), lesser Zyudenryu that had supported the Ten Great Zyudenryu in their fight against the Deboth Army until the loss of their physical bodies to Gadoma, but their Zyudenchi can be used to activate special abilities.

It has also been shown that the Deboth Army is capable of creating their own Zyudenchi that are activated with the call of "Deboth In!" (デーボスイン!).

The Kyoryugers use the batteries to access special abilities or weapons as well as power up the Zyudenryu to their Battle Modes (戦闘モード) so they can fight more effectively and combine with other Zyudenryu. When in combat, the Zyudenchi are stored in the MoBuckle.

On the other side of the Zyudenchi are the names of the Zyudenryu and Guardians that they correspond to in English lettering.

Whenever the Kyoryugers' arsenal or a Zyudenryu "bites" a Zyudenchi, it produces a sound saying "Gaburincho" (ガブリンチョ). When the Zyudenchi are not in use, they are kept in the Charge Box (チャージボックス) in the Spirit Base to recharge their Brave reserves.
