Replacement battery MB466LL/A

Hello,

I finally gave up on my original Apple battery for my Macbook 13" aluminum late 2008 and replaced it a couple of days ago with a "BULL-TECH A1280 Battery Replacement New Laptop Battery for Apple A1280 A1278 (2008 Version) MacBook 13-Inch Series" from Amazon.

I think I let the battery discharge to 2%, I was in the middle of a project and I am pretty sure that it's the new battery that I discharged to 2%. It is now fully charged at 100%.

I have not yet unplug the charger, working on my desk. However, the battery icon shows a zigzag/lightning sign on it, which the original battery showed when it needed to be replaced.

Is something wrong with this brand/battery? It got good reviews on Amazon.

Thank you!

MacBook, OS X 10.11

IF the battery & charge system is not calibrated, the battery gauge may be inaccurate.

And if you've replaced the battery and never tried the answer, it may be the cure. An

official (to spec if a quality third party replacement) has a memory chip inside, too.

First mistake with these, is to run battery near zero power; then expect to revive to full capacity

& also never 'calibrate' the battery. ~ I've no experience nor any brand familiarity with 'bull-tech.'

My portable Macs have replacement cells and I've re-calibrated them on more than one occasion.

Thank you for your reply.

The battery is fully charged at 100% capacity, that's not a problem. I just question why there is zigzag sign on the battery icon. Is it because it is not an original Apple battery?

Thanks!
