Energy Shield shown over mana, instead of life.

Eldritch Battery (often referred to as EB) is a keystone passive skill that makes energy shield protect mana instead of life.

Mechanics

Energy shield protects mana instead of life. All modifiers to energy shield apply normally but it is not affected by modifiers to mana or mana regeneration. Energy shield recharge and recovery through Zealot's Oath or Ghost Reaver function normally. Any reductions to mana (e.g. skill costs) will instead reduce energy shield by the same amount.

Energy shield recharge starts instantly without 2 second delay and taking life damage or spending energy shield on skill cost will not interrupt/delay energy shield recharge.

Using Energy Leech Support while having Eldritch Battery allocated will cause you to leech energy shield in a similar way to leeching mana if mana was your primary pool.

With regards to skills like Blood Rage and Righteous Fire, Energy Shield is still counted in the degeneration applied to health.

Eldritch Battery also causes energy shields to no longer grant a chance to avoid stun.

Eldritch Battery does not protect mana against Chaos damage that is redirected to mana (ex. Mind Over Matter or The Ivory TowerThe Ivory Tower

+30 to maximum Energy Shield per 100 Reserved Life
+(80-100) to maximum Mana
Regenerate 2% of Energy Shield per second
Chaos Damage is taken from Mana before LifeThe mind is a filter through which anarchy becomes order.). Chaos Damage will apply directly to the underlying mana pool, and failing that, life pool. Non-Chaos damage types redirected to mana drain energy shield first, but also interrupt energy shield recharge, unlike spending mana on skill costs.

Location

Eldritch Battery is a standalone keystone located on the upper right edge of the skill tree.
