Hmmm....they (Arizer) told me that at the moment the (upper) red light starts blinking, there is a 20% charge left....
But how to measure anything like that ?
You misread what i said.. i was talking about the YELLOW lights.. not the red. You can measure it with a watch and some patience.. just need to let it run until the red blinking light, and then charge it and then run it again until it cannot be turned on. BUT, i wouldn't advise doing this because li-ion batteries need some charge left to properly function and recharge.
I think you should take the experience of FC users over what you read in retailer allegations, and even Arizer sometimes.
To sum it up it goes like this:
- ~2hours of usage with a full charge
- recommended to charge after every bowl
- recommended to not let it go past all the yellow lights go out (reported ~40% battery left)
- strongly advised to not fully deplete the battery ( possibility of permanently damaging it), at least stop when the 20% red light warning turns on.
With this in mind, you can do as you please. The recommendations are just for a longer battery life, no need to be strict.
Also, i suggest getting a new battery to see if the issue is with the battery and not the unit. My Solo has worked fine from day one ( M1A3 version), and i never had any problem whatsoever.
And if i do, Arizer seems to respond pretty quickly and with the costumer in mind so i'm not concerned if i run into trouble expect for the hassle of having to deal with it.
Hope you sort it out Indy, with the tasty varieties you can get over there and the more open policy, it would be a shame to not have a working Solo.
