How to Make RE-Battery in Minecraft
RE-Battery
RE-Battery is the entry-level rechargeable 10,000 EU battery from IndustrialCraft 2, crafted from 4 tin casings, 2 redstone, and 1 insulated tin cable.
Description
RE-Battery is crafted on a vanilla crafting table from 4 Tin Item Casings, 2 Redstone, and 1 Insulated Tin Cable: the cable sits in the top-center cell, with casing–redstone–casing rows filling the middle and bottom. A charged RE-Battery powers IC2 electric tools in the field: hold right-click with a single battery in hand to top up a Drill, Chainsaw, Electric Wrench, Electric Hoe, or Electric Treetap. Dropping a charged RE-Battery into the bottom slot of a BatBox, MFE, or MFSU returns its EU to the network. Unlike the Single-Use Battery, the RE-Battery never disappears when empty — recharge and reuse it indefinitely, then upgrade to the Energy Crystal (1,000,000 EU) or the Lapotron Crystal (10,000,000 EU). BatBox, Generator, BatPack, and Charging RE-Battery recipes all spend RE-Batteries.

Guide
How to craft and charge a RE-Battery in IC2
-
1
Gather ingredients
Collect 4 Tin Item Casings, 2 Redstone Dust, and 1 Insulated Tin Cable.
-
2
Lay out the 3x3 recipe
Top row: empty, Insulated Tin Cable, empty. Middle and bottom rows: Tin Item Casing, Redstone, Tin Item Casing in each. The pattern yields one RE-Battery.
-
3
Charge the battery
Place the RE-Battery in the top charging slot of a BatBox, Generator, MFE, or MFSU and wait until its charge bar is full.
-
4
Power an IC2 tool
Hold right-click with the single charged RE-Battery in hand to refill a Drill, Chainsaw, Electric Wrench, Electric Hoe, or Electric Treetap on the spot.
-
5
Reuse or discharge
Recharge the same RE-Battery whenever it runs empty. To return stored EU to the grid, place the charged battery in the bottom slot of a BatBox, MFE, or MFSU.
Fully charged and fully discharged RE-Batteries stack up to 16; partially charged ones never stack. Charge spare batteries before a mining trip so the inventory stays tidy.

Frequently asked questions
How much EU does a RE-Battery hold?
Up to 10,000 EU at power tier 1 (Low Voltage) — the entry-level buffer of an IndustrialCraft 2 energy network.
Will a RE-Battery explode from MV or HV current?
No. RE-Batteries are charged through item slots, and the top slot of an MFE or MFSU charges a tier-1 battery safely. In IC2, over-voltaged cables and machines explode — not battery items.
Which tools can a RE-Battery charge?
Every IC2 electric tool, including the Drill, Chainsaw, Electric Wrench, Electric Hoe, and Electric Treetap. Hold right-click with a single battery in hand until the tool's charge bar fills.
Does the RE-Battery disappear when empty?
No. Unlike the Single-Use Battery, the RE-Battery stays in your inventory and can be recharged indefinitely.
What replaces the RE-Battery at higher tiers?
The Energy Crystal with 1,000,000 EU and the Lapotron Crystal with 10,000,000 EU; both charge in the charging slot of an MFE or MFSU, with the Lapotron requiring MFSU-class equipment.
What is crafted from RE-Batteries?
Early IC2 infrastructure runs on them: the BatBox, Generator, BatPack, and Charging RE-Battery recipes all spend RE-Batteries.
