The process is real easy! Working over a dish to catch any spill, use a small knife pry up one side at a time until the back unclips.
Then pry out the black rubber seal that covers the circuit board. The battery is then exposed. Unclip the circuit board on the side
with the battery and lift it up. Use something non-metalic to brace the circuit board up so as to make it easier to solder.
Unsoldering and soldering the battery is up to your ability. Then return any spilled or removed oil and reverse the process to seal back the
unit. Its not that difficult just take your time.
