When I try to turn on my macbook with battery in, it doesn't startup. When its plugged in to charger, it turns on, then shuts down after few minutes. Without the battery and just charger it starts fine and I continue using it. Do you think the problems with the battery or with circuit that charges battery?

This all points to a bad battery- what is the model number of your Mac? If you give it to us I can then direct you to the proper part.

My macbook pro 2012 has similar yet a different problem...my compute starts, but I wont hear the fan running or apple logo. After I shut it down and unplugged the AC plug and plugged it back, then it boots up but I wont see the apple booting still. I recently installed a new ssd and had no problem until now...could it simply be the battery being out of juice ?...besides, I did notice a message saying my battery needs a soon replacement so...thought ?
P.s: I opened the under cover and seen my fan running, just not strongly as usual, like it would on normal booting.
My model is a Macbook pro 9,2

1. Verify that you have all updates installed, particularly Battery Update 1.4 (KB# HT3421)
2. Reset the SMC (KB# HT3964)
3. Reset your PRAM (KB# HT1379)
1. Remove the battery and AC power
2. Press and hold the power button for 10 seconds
3. Reinstall battery and power
Given this model's track record its probably the battery but SMU's do go on the fritz every now and again (plus resetting the SMU doesn't cost any green).
All MacBook batteries are the same so don't worry about getting your model number (ie. if you really wanted you could put a black battery in a white MacBook, dalmatian style).
Selected battery issues are covered by a Repair Extension Program for which no model is eligible after 3 years from the date of purchase. Eligibility must be determined by an Apple Authorized Technician and repairs fulfilled at option by Apple.
