The Lightning Rod creates a 
Battery Pack the day after getting hit by lightning during a storm. It is not necessary for the player to be on the farm when the lightning strike happens.
Since rods do not protect a specific area, the exact placement of a rod on the farm has no bearing on its chance to intercept a lightning strike. A Lightning Rod has a very good chance of intercepting a lightning bolt if it isn't already processing one.[1]
Since each rod only protects the farm from harm if it is not already processing a previous lightning strike, it is advisable to place multiple rods on the farm. The number of lightning strikes during one day is random.
A lightning rod is the reward for completing the 
10,000 Bundle in the Vault.
Chance to Intercept
The chance that a lightning strike will be intercepted is inversely related to the percentage of lightning rods on your farm that are currently holding a charge (either pulsing or holding a battery pack). The exact probability is chance to intercept = 1 - (number of charged lightning rods / total number of lightning rods)²[2]. That is, if none of your lightning rods are currently holding a charge, a lightning strike is 100% guaranteed to be intercepted. If 50% of your lightning rods are charged, a lightning strike has a 75% chance of being intercepted. If 90% of your lightning rods are charged, a strike has only a 19% chance of being intercepted. You must have at least one lightning rod on your farm to have any chance of intercepting a strike.
A non-intercepted lightning strike has a base 25% chance of hitting a feature on your farm, influenced by daily luck and luck buffs.
Notes
- Though it is possible to place lightning rods outside of the farm map, they will never get hit by lightning there, and thus will produce no battery packs.
- Storms (and thus lightning) never occur in Winter.
- More lightning will strike the longer you stay awake, necessitating more lightning rods and giving potential to produce more Battery Packs.

History
- 1.4: Lightning Rods are now ready to harvest the day after a storm, instead of 24 hours later. Lighting Rods can now be stacked in a player's inventory and in chests.
