What are these basic components?

Never mind what I'm doing here: I'm not even sure, but I would like to at least know what I'm looking at and you'll notice these two bulbs along both separate cables. The first one is at the end of a laptop power adapter. It already has it's transformer at the wall connection like most standard power adapters. The second one is attached to an external laptop batter charger, which also has it's own separate transformer, which I lost, hence this Frankenstein project.

So... I've ended up with two of these weird bulb'ish components which I'm wondering is the cause of my slow -as-molasses charging.

Anyone know what these are? Thanks.

 

Thanks Harold. http://www.amazon.com/External-batt...ry/dp/B00FIJZAU8#immersive-view_1454189197895

Hope that helps. Both charging cables are designed to charge the same battery, but one is directly, the other through the computer. So if I had the original transformer for the external charger that would work perfect, otherwise obviously charging the battery through the computer with just the laptop power adapter also would charge perfectly, which it does but I'm trying to have a two charged batteries setup for long distance computing. Planning on getting a third battery if I can't get these batteries to charge externally faster than 11 hrs lol.

 

There is no other indicators on that component to make use of a closer-up view of it unfortunately.

 

If we can assume the original laptop power adapter has the correct settings should I just splice it directly to battery right at the external cable's connector pins before that bulb? Or does not the laptop power adapter connect to the battery directly through the laptop but go through other important circuitry?

 

Well thanks anyway. I'll report back if I decide to open it up. Can ya narrow it down to a couple possibilities?

 

Alright. Thanks Harold

 

Harold! It says "MPU" in it. Missed that earlier. What does that mean? I want to cut it out to hopefully free up some current/voltage to get this to charge faster. Unless you think that means something important like micro processing unit ... Could it? I've read laptop battery charging and the batteries themselves are complicated. That the batteries have computers in them themselves. What do you think?

 

Yeah, the "other one", not this one, hence my persistence. Don't suppose you have any idea what MPU stands for do y'a?

 

You reprimanded me for not paying attention when I was already told about the one on the left, which I pointed out want the one on the right, which is... Never mind. Anyway. You've left me no choice but to put it under the knife. TBC...
