The script works only if the battery is in the charachter

[vague cipher]

g

local player = game.Players.LocalPlayer

local backpack = player:WaitForChild("Backpack")
local starterGear = player:FindFirstChild("StarterGear")

local function alreadyHasBattery(excludeTool)
local function check(container)
local tool = container:FindFirstChild(batteryName)
if tool and tool:IsA("Tool") and tool ~= excludeTool then
return true
end
return false
end

if player.Character and check(player.Character) then
    return true

if backpack and check(backpack) then
    return true
