How do I replace the batteries in a Satisfyer vibrator?

To replace the batteries in a Satisfyer vibrator, one must first locate the battery compartment. Usually, it can be found at the base or handle of the device. For models with a twist-off cap, one simply twists the cap counter-clockwise to open the compartment. For other models that might have a push-and-slide mechanism or clips, gently applying pressure will open the compartment. Upon opening, one should carefully remove the old batteries and take note of their orientation. Then, replace them with new batteries, respecting the correct polarity (matching positive "+" and negative "-" ends as indicated in the compartment), before securely closing the compartment. It is important to refer to the user manual for the specific model for precise instructions, as battery type and placement can vary between different Satisfyer models. After replacing the batteries, ensure that sealing rings and caps are properly reattached to maintain waterproofing features where applicable.
