Battery replacement problem, mac does not turn on after discharging

Hello i bought 2 batteries because old one stoped to work. I have such problem that mac turns on when i plug it in. After that i can unplug it and it will work on battery, but then after complete discharge it does not turn on after i plug it again. Generally it starts to turn on when i unlug battery from motherboard and plug it again. The same problem is when my battery is charged but i turn mac off. I can turn it on when i unplug battery from MO and then plug it to MO and plug mac to charger. Those two batteries work well. They have 1-3 cycles and good capacity. Everything works good, but it does not start after turning off or discharging :(

Let’s get a better idea what’s going on. Download this gem of an App CoconutBattery with the MagSafe charger plugged in take a Snapshot of the Apps main window with the Battery tab opened up and post it here for us to see.

@lukaszartemiuk - OK, while the batteries cycle count is very low, the age of this battery concerns me! It’s over five years so it’s chemistry it not at its prime. So it likely needs a new battery soon.

At this point your system should work, so something else is effecting it. From your description it appears SMC is going into a latched condition not a battery issue.

Let’s do one more test here, restart your system and press the D key to enter the onboard diagnostics. See if it reports any errors let us know what you get.
