Panasonic Shaver

You are bidding on one brand new rechargeable replacement battery for Panasonic Shaver ES series for the following models: ES-GA20 ESGA20 only Note, if your shaver uses only one battery and the battery type is Li-ion (not Ni-Cd / NiMH types), this is the right one. Otherwise, it is not the battery for your shaver. But, you may check my other listing for your shaver model number.  This battery does NOT fit old model shaver (like, over 5 years old shavers.), like, ES4000 series (like, ES4000, ES4001, ES4025, ES4026, ES4027, etc.). Replacing the battery is very easy. All you need is a Phillips screwdriver and about 5 minutes of time.
Note, Different models of the Panasonic shavers have different structures. But, the basic open procedures are the same. The above are DEMO only two references that show you how to open. You will get one battery + one tube of waterproof grease from this auction. Warning: Your Panasonic shaver may become NOT waterproof anymore after the battery installation since the waterproof rubber O-ring and (for some models) the rubber washers on the screws might not be water tight like before. To prevent this happening, you need to do 2 things, 1st. to make sure the screw rubber washers (if any) are not lost since they are very tiny and easy to get lost. 2nd, to apply the special waterproof grease on the rubber O-ring. If water leak through into shaver, it will damage the shaver circuit for sure so that you shaver will NEVER work again. ====================================================================================================== The direction of use of the waterproof grease: This grease is specially made for water proof O-ring or gasket which used on your Panasonic waterproof shaver after you change the batteries. It will prevent the shaver from water leaking through to damage the circuit. Normally, after you opened your shaver for repairing or changing battery, the shaver will become not waterproof so that the leaking water will ruin the shaver and put your repair work in waste after you reassemble the opened shaver parts back. With this grease, you only need to use your finger to apply a thin layer of this grease on the O-ring / gasket. Your shaver will be restored to the waterproof shaver again. It will not damage the rubber of the O-Ring as the design, not like other kind of greases. This is the same grease that OEM uses when installing the O-ring at the factory.  It is a silicone based grease that is very stable and inert. It will not oxidize as the petroleum based grease.   The very high viscosity of the grease will help to improve the seal to prevent water from leaking through. Please feel free to ask me questions.
