3.7 battery question

[VEGETAtion]

i have four 3.7 batteries, but two of them are from different makers
EX. 2 from Samsung phone
1 from phillips mp3 player
1 from different phone

would i still be able to use them all as one 14.8 battery? (of course after soldering them together) ((im a newb ))

I would not suggest using different brand batteries together at all.

They're probably all different amp-hourages. That's no good.

what if i use the two that are from the same phone?

same model too?
would possibly work, will probably work if it has the same amp hourage.
