The world runs on energy. It's how planet Earth and everyone on it lives their lives, and though it may have magic, monsters, and Dinosaur Eggs, everyone's favorite farming game Stardew Valley can be surprisingly down to earth. Just take the Battery Pack item, for instance.

This handy item is necessary for the crafting of several electronic/machine-related items, including the Crystalarium, Lamp-Posts, and Mini-Jukebox, to name a few. It's also required in several important quests in the game, so it's very important to know how to get a good, steady supply of them. Let's dive right in and see what Battery Packs are all about.

Updated March 9, 2023 by Rebecca Phillips: Battery Packs are an indispensable item in Stardew Valley thanks to their varied uses in recipes and quests. For that reason, we've updated this guide to make the information as easy as possible for you to find. Here, you'll find every way to obtain Battery Packs as well as all the item's uses in the game.

How To Obtain Battery Packs

As of Stardew Valley's 1.5 update, there are two main ways you can obtain a Battery Pack, though the first way is the most accessible in the early game.

If you're using Lightning Rods to collect Battery Packs, the Rain Totem can only make the next day rainy, unless it is used on a day that is currently stormy. That will cause the next day to be stormy as well, increasing your Battery Pack haul.

Other ways Battery Packs can be obtained included:

• Five chance of being dropped after slaying an Iridium Bat.
• Randomly sold by the Traveling Cart for 1,500-2,500g.
• Rare drop from breaking boxes/crates in the Skull Cavern.
• Possible gift from Pam and Kent in the mail (chance increases as their friendship level increases).
• Rewarded for completing the Children's Bundle.

Who Should You Gift Battery Packs To?

Like most other items, the Battery Pack can be given as a gift to other characters, but there's only one character who loves receiving the item: Maru. This makes sense (along with her love of Gold and Iridium Bars) due to her gadget-building and love of technology.

Every other character in the game Dislikes the Battery Pack, meaning it's usually best to keep them for yourself instead of giving a disappointing gift.

How To Use Battery Packs For Crafting

The Battery Pack is vital for building up an efficient and profitable farm because of the many crafting recipes it is needed for.

Item	Recipe	Use
Iridium Sprinkler	Unlocks at Farming level 9 and requires: 1 Battery Park 1 Gold Bar 1 Iridium Bar	Maximize your crop production by watering 24 adjacent tiles instead of 8
Crystalarium	Unlocks at Mining level 9 and requires: 1 Battery Park 99 Stone 5 Gold Bars 2 Iridium Bars	Crystalariums replicate whatever gem is put inside them after a certain period of in-game time. Diamonds are the most profitable to copy, while replicating Quartz will give you a steady influx of Refined Quartz resources
Slime Egg-Press	Unlocks after reaching Combat level 6 and requires: 1 Battery Pack 25 Coal 1 Fire Quartz	By putting 100 Slime pieces into the Slime Egg-Press, it will produce a randomly-colored Slime Egg after 21 hours in-game. The odds for stronger slime colors are rarer, but not impossible.
Wood Lamp-Post	Purchasable at Robin's Carpenter Shop for 500g and requires: 1 Battery Pack 50 Wood	A light source that can be placed in your farmhouse or shed.
Iron Lamp-Post	Purchasable at Robin's Carpenter Shop for 1,000g and requires: 1 Battery Pack 1 Iron Bar	The same as the Wood Lamp-Post, but made of iron.
Mini-Jukebox	Reach five hearts with Gus and leave the farmhouse between 6-11:30am (on a non-rainy day) to trigger a cutscene where Gus gives you the Mini-Jukebox crating recipe. It requires: 1 Battery Pack 2 Iron Bars	This handy device acts just like the Saloon's Jukebox, but can be placed anywhere on the farm to provide you with your most favorite Stardew Valley tunes! It won't work in the rain, however.
Farm Computer	You'll be given the recipe by Demetrius after completing his Special Order, which involves catching ten fish of a random kind. The recipe requires: 1 Battery Pack 1 Dwarf Gadget 10 Refined Quartz	Offers you valuable information about your farm, such as amount of Hay, Forageable items, machines finished working, and even which crops are ready to be harvested.
