Questions regarding m15x SB Battery

I've been using my m15x with the smart bay battery for work for the past few months. It's just recently that I noticed the way the battery gets charged and drained.

When using just battery power, the m15x seems to use up the smart bay battery first. When it's down to about 10% left, the main battery will be used. When the main battery drops to about 60% or so, it would again use the smart bay battery until it reaches 0%.

Now the thing is, I've read somewhere that batteries should not be allowed to be totally drained. Is this what's happening when the SB battery reaches 0%? Do you guys just leave it and let it be?

 

The battery isn't allowing itself to be totally drained due to an auto shutoff in the SB. -Although someone needs to confirm this.
Usually it is only rechargeable lithium batteries by themselves (ones that you get in Pencil Battery format, ones that require special chargers and adapters to use) that you can't let to get to 0%.

I would only assume that these SB and laptop batteries have fail-safe's to prevent this final discharge from happening.

 

i don't think you have anything to worry about, the battery's capacity is probably just showed as "0%", even though there's a bit of juice left. as luxury said, there's probably some sort of fail-safe. kinda like in cars, even when the gas tanks shows empty, there's still a few litres inside for safety reasons.

 

Yeah thanks for the confirmation luxury and whizzo.

So I'm guessing this fail safe also works for the main 6 cell battery of the m15x as well?

 

it stands to reason, yes.
