Battle Drill is one of the most popular siege machines in Clash of Clans.
Currently, there are five levels available for this siege machine.
It is quite common for players to forget about the upgrade cost of Battle Drill and their corresponding upgrade time.
To solve that issue, I've come up with this article!
In this article, I've listed the upgrade cost, and upgrade time of Battle Drill in Clash of Clans.
I've done all the math required so that you don't have to!
So, without any further ado, let's dive right into it!
Battle Drill Upgrade Cost and Upgrade Time in Clash of Clans
I've organized the entire data in a table.
Moreover, to make sure that everything is easy to read and understand, I've also written the data in text in an organized manner.
The following table displays the upgrade cost, and upgrade time of Battle Drill in the game:
| Battle Drill Level | Upgrade Cost (elixir) | Upgrade Time |
|---|---|---|
| 1 to 2 | 6,000,000 | 4 days |
| 2 to 3 | 8,500,000 | 5 days |
| 3 to 4 | 10,000,000 | 8 days |
| 4 to 5 | 19,000,000 | 13 days 12 hours |
The data in the above table can be interpreted as:
- To upgrade a Battle Drill from level 1 to level 2, you'll require 6,000,000 elixir. The upgrade will take 4 days to complete.
- Upgrading a level 2 Battle Drill to level 3 requires 8,500,000 elixir. And, the upgrade gets completed in 5 days.
- To upgrade a Battle Drill from level 3 to level 4, you'll need 10,000,000 elixir. The upgrade will take 8 days to complete.
- Upgrading a Battle Drill from level 4 to level 5 requires 19,000,000 elixir. And, the upgrade gets completed in 13 days 12 hours.
Conclusion
In this article, I've listed the upgrade cost of Battle Drill along with the corresponding upgrade time.
I'll also update the data in this article if any numbers change in the game in the future.
Also, please note: I've updated the data in this post. The entire data in this post is up-to-date as of 2 October 2025.
Now, I'd like to hear from you:
Have you already maxed out the Battle Drill in your base? If not, what's the current level of the Battle Drill?
