Can I run a macbook a1990 2018 with a disconnected battery?

Good afternoon. Now I live far away from civilization and had to order a battery, instead swollen. After replacing the charging is not performed and generally a computer as dead, but visually no damage. Used normal tool for removing loops a plastic spatula.

The service said that the battery may be marriage and need to disable it to check it, but it glued already and this is causing the problem. Also, the problem is that I'm not sure that without a connected battery can provide voltage.

Actually this question and please reply, is it safe to apply the voltage with the battery disconnected and could really be the problem?

If the laptop to connect to the UPS or through a surge protector, it's safe. If not them, then the voltage drop will tell gland Dasvidaniya. Because the battery and the power controller and filter
Is the stabilizer. But the question is still relevant, it really can be trouble in the battery. And how best to isolate the contact area with the means at hand - corine67 commented on April 19th 20 at 12:30

@Aaron, I need to move the terminal from the pad, disconnecting the power bus and to try to apply tension? It confuses me that on the English forums, write that to do so is needless, but the reason I never found. - corine67 commented on April 19th 20 at 12:36
Relle is, the voltage in the power supply the MacBook, overvoltage - PSU just turns off the power supply, while the MacBook can withstand more peak power PSU. - jarod_Nicolas commented on April 19th 20 at 12:39

To start the MacBook without the battery, just disconnect the connector of the battery on a small Board which is screwed a bolt 1m large and one small loop. I think he included just sticking the charging cable and pressing the power button...
But most likely you have a dead battery, cover, USB-C controllers. I had just such a problem. MacBook it is charging then there is no first time out - was on charging, everything is OK like it was but just dead at 0... is that a small Board to try to resuscitate him. I would not shut off until the battery and tried to find BP weaker, perhaps from some Android Wat 15-30.
I have the problem with usb chips the MacBook worked fine from the usb-c 15W, not cut down and not discharged if it is not loaded. And with the native PSU it either didn't work at all, either through time it hath (lie down when a couple of days) , it is about 30 minutes and charged again, missing charging... If the symptoms are similar - that is exactly what usb-c controller!
