Shipping mode forces the Roger to not turn on even though the switch might have failed in such a way that it will not shut off even when disassembled and the on-off switch is confirmed to be in the off position.

The other answer covered it pretty well but I’ll just add: it’s not something you should ever need if the Roger on is working correctly.

Thank you. I’ll give it a try, because despite not obvious problem with the switch my Roger On V1 no-In discharges pretty quickly when unused (about ~50% after last full charge 1-1.5 month ago).

@danka, great info; I am considering buying it.

Make sure the plug in head is correct. Attached pls find a photo for your info.

Maybe check with @CombatWombat on the type of plug head used. CombatWombat photo is 3 wires. Above photo is 2 wires. Chat with supplier and send them photos to confirm.

There are many manufacturers in China. The company name mentioned Roger li-polymer (Lipo) battery looks like a trading company in Hong Kong ( I might be wrong). The code on the Roger Lipo is 471736 is the measurement of the Lipo battery. For example - 5/20/30mm (HWL) - 052030 code. So 471736 should be 4.7mm (Height) x 17mm width & 36 mm length. Capacity is 260mAh and a voltage of 3.7V. Have to spend sometimes to search for 3 wires and a similar plug head.
A electronic mobile phone shop might be able to get it change for a fee should the plug head is wrong.
Keep searching on Ali Express.

This is a 3 wires LiPo battery with measurement closer to 471736. Attached website for your info.

Can you post an address for this battery. Either here or PM. thanks.

Take a photo shot of the connector pin. The 3 wires LiPo battery show on Ali Express is call “JST 3 Pin - 1 mm connector”. If your photo shot is similar, then it is plug and play!
Chat with them before you buy.

Hi CombatWombat, I am from Spain, Thank you very much for the good information. I have tried to dismantle the ROGER ON. I am not able to open it with a TORX T3. is it the right screwdriver?

My old V1 Roger ON needed both TORX T2 & T3 drivers to open. Not sure about newer models.

Try @raylock1 He’s dissembled tons of Rogers.

Good Luck,

David

I used a Torx T3 screwdriver that I got from Amazon on my Roger On IN v1.

Thank you very much Raylock. It is of great help. I really appreciate it

More like three or four. And I was even able to put two or three of them back together again

Just did this. 2 screws closest to the USB port are T3s and the other 4 are T2s. Very tiny. The round part didn’t look that much wider than the rectangular part so I decided not to try to fill it in. I just made sure the switch was lined up and put it back together and now it seems to turn off again. Fingers crossed.
