The Battery Problem in Alan Wake 2 is one of the toughest math puzzles you'll find while exploring Wateree. On the lid of one of the cult's caches there is a piece of paper with an unusual riddle, and the box itself is locked with a lock with a three-digit numeric code.
To find out the correct combination you need to create an equation and solve it. It's important to open the box if you want complete the game 100% and get an achievement "Secret caches" [Secret Stashes] for collecting all cult caches. This guide will tell you how to solve the battery problem in Alan Wake 2 and calculate the correct code.
How to solve the battery problem in Alan Wake 2
The cult cache can be found in the southeastern docks, located south of Suomi Hall on the western pier in Wateree. The secret cache with the riddle is located directly behind the blue containers.
In a separate article they told where to find all the cult caches in Alan Wake 2.
On the lid of the cultists' hiding place you will see a note containing a puzzle about batteries in Alan Wake 2. To find out the correct combination of the combination lock and open the box, you have to solve a small algebraic equation based on the conditions of the riddle.
The text of the note reads: «Problem about cars lightness! Here is mine: there are 3 batteries (B1, B2, B3), the total charge power of which is 1600 amperes. B2 has 128 more amps than B3. B1 has twice as much charge as B3. What is the charge of battery B2?”
How to write an equation
It is necessary to calculate the battery charge in Alan Wake 2 to open the combination lock. The total battery charge is 1600 amperes:
- B1+B2+B3=1600.
B2 has 128 amps more than B3:
- B2=B3+128.
B1 has twice as much charge as B3:
- B1=2B3.
Compose an algebraic equation based on the text from the prompt:
- B1+B2+B3=1600
Replacing B1 and B2 with their corresponding expressions gives a new equation:
- 2B3+B3+128+B3=1600.
Next, you need to simplify everything and perform mathematical calculations to get the following:
- 4B3+128 =1600;
- 4B3=1472.
By solving a simple equation you will find out the charge of battery B3:
- B3=1472/4;
- B3=368.
Correct code combination
You can find out the correct code combination by answering the question in the problem “How much charge does battery B2 have?”. According to the condition, B2 has 128 amperes more than B3, so the answer to the riddle is calculated as follows:
- B2 = 368 + 128;
- B2 = 496.
Once you have calculated the correct code, use the numbers 496to open the cache. Inside you will find useful consumables for the Saga:
- Crossbow bolts;
- Wound dressing kit;
- Cartridges for shotgun.
We hope this guide helped you create an equation and solve the battery problem in Alan Weick 2. If you have any difficulties or questions, please write to comments, — the author or other players will try to help. Read more in the corresponding section of our website Alan Wake 2 articles.
