How to Replace Energizer Induction Batteries in a Wii Remote

Energizer induction batteries are a great addition to any Wii remote controller. However, like any rechargeable battery, the batteries ultimately need to be replaced. Unfortunately, Energizer does not seem to sell replacement battery packs. Instead, you are expected to buy the entire charger again, which is expensive and wasteful. This tutorial will show you how to replace the batteries inside the inductive battery pack, for much less than what it costs to buy a new one. Luckily this is simple enough that anyone can do it! Required: 2 rechargeable AAA batteries Phillips head screwdriver Knife or small flathead screwdriver Approximately 5 minutes

Remove the battery pack from the controller and locate the two screws. (original batteries shown removed, for reference)

Remove the two screws, and then pull the battery pack straight up and off of the back cover. Note that the correct polarity of the batteries is marked on the housing.

Use a knife or small flathead screwdriver to pry the two halves of the housing apart. Luckily these separate cleanly since they are not glued together. Replace the batteries with a fresh set of rechargeable AAA's, noting the polarity that was marked on the housing in Step 2. Carefully replace the housing, being careful to properly align the metal leads into the slots in the housing. Press the housing together, slide the battery pack over the posts in the back cover, and replace the screws.

Be sure to monitor the first few charges to be sure the charging lights on the base charger don't blink red, and that the batteries don't overheat. Then enjoy the battery life on your new batteries! You have just saved yourself about $30!

Disclaimer! This process was successful for my specfic induction battery charger. However, at any time Energizer might redesign the product. I am not responsible for any harm or damage done from following this tutorial! If you have any doubts, just buy a new charger!
