Sena 3S BAD BATTERY!!!!
Hi everyone,
so I bought myself the Sena 3S Unit (the 3S-W to be specific) a couple of weeks ago.
First Problem: the unit would not charge correctly. I used a normal wall charger with the supplied USB cable (5V; 1A). The Unit charged for hours, but the LED light would not turn blue.
After using the unit for appr. 5 Minutes, it turned off due to low battery. I tried this procedure about three times...all with the same result. So i figured, it must be a faulty battery.I returned the unit (through Amazon) and received a new one straight away.
Now: this unit is just as bad!! First i charged it and the red charging light turned blue after app. 2 hours....so far so good.
After fully charging the unit, i unplugged it, made sure it was turned off, and placed my helmet in the storage for two days. Today, I put the helmet on and tried to turn on the unit...NADA...BATTERY ABSOLUTELY DEAD! This shouldn't be after two days with the unit off!!!
So I decided to charge it again...after two hours the charge was complete and I went directly for a ride. After exactly 2 hours riding and just listening to music over the unit, the 3S turned itself off due to low battery..... THIS IS PRETTY RIDICULOUS!!!
Anybody else experienced this kind of behavior? I would say its a faulty unit, but I'm already on my second one, as the first one was already faulty!!

I just bought a 3S-W - charge LED lights up, but still won't turn on even after a couple hours on the charger.

I've had almost the exact same problem. The last time I tried, the battery only charged for about 30 minutes before the LED turned blue.

Same here. As anyone determined a fix or is this just a faulty unit?

Just bought a 3S. Been charging it for a few hours (all night actually), blue light came on, and now unable to pair to my phone. It seems it won’t turn on.
It’s going back! What a drag.0
