You are currently viewing Raft – How to Charge Battery

One of the items you need for starting story missions in Raft is the Battery. It is also a crucial part of many machines that help you with repetitive tasks, such as the Sprinkler and the Recycler.

However, a Battery won’t last forever. Sooner or later, you have to replace it with a new one or use the upgraded version, Advanced Battery, to increase the use time.

Crafting batteries is expensive, especially in the game’s early days, which is why it’s essential to learn how to charge batteries in Raft.

You can use either a Battery Charger or a Wind Turbine to recharge a Battery in Raft. The Battery Charger can be found quite early in the game and requires Biofuel to charge batteries, while a Wind Turbine uses wind power to recharge batteries at zero cost.

How to Charge Battery in Raft

Since it’s possible to recharge batteries in Raft, it’s advisable only to craft a new Battery if you really need to or have plenty of resources.

Otherwise, it’s best to wait until you reach the fourth story island – Caravan Island.

Battery Charger

On Caravan Island, you’ll find three Battery Charger Parts that unlock the Battery Charger blueprint. Make sure to complete the story here to get the Metal Detector blueprint as well, as you’ll need this tool to find Titanium.

Next, return to your raft and research the Battery Charger recipe. By this point, you only need to research 1 Titanium to unlock this recipe.

Open the crafting menu, go to the Other tab (the second tab), and craft a Battery Charger using 15 Plastic, 5 Scraps, 1 Circuit Board, and 4 Titanium Ingots. Then, place it on your raft.

You’ll see two empty slots and a tank with a gauge on top of it. First, put Biofuel in the tank to fill the gauge. Then, put a Battery in one of the empty slots to recharge it.

You can recharge two batteries simultaneously. The time to fully recharge a Battery is 185 seconds. Once the batteries are fully charged, the Battery Charger will turn off to save Biofuel.

You can also connect the Battery Charger with a Biofuel Tank using Fuel Pipes to partially automate the refueling process.

Wind Turbine

Since you need to use Biofuel for other machines (Engines, for example), it can be a bit inefficient to recharge batteries using the Battery Charger.

So, what is the most efficient way to charge them?

On the sixth story island, Varuna Point, you’ll find an extremely useful blueprint that unlocks a way better recharging method – the Wind Turbine blueprint.

It doesn’t require any new materials, so you can learn the recipe right away. After that, you can craft it with 20 Planks, 8 Ropes, 4 Titanium Ingots, and 4 Circuit Boards. You need to place it somewhere high on your raft.

Since wind power is stronger at high altitudes, batteries are charged faster when the wind turbine is up higher. The higher, the better, up to a maximum height of 3 walls tall.

The table below shows various heights and the corresponding time needed in seconds to recharge both versions of the Battery in Raft.

While placed on the highest floor, the Wind Turbine charges batteries faster than the Battery Charger.

It also has 4 charging slots and costs you nothing but time, making it the best method to recharge batteries in Raft.

That’s how to charge batteries in Raft!
