Laptop Batteries - Not Equal

Here's a precaution if you are out buying a replacement laptop battery.  I decide it was time to replace the battery on om HP DV6-2190US laptop.  Checked on line the availability of the battery with the local Interstate Battery store.  They had them (both the standard and the high capacity batteries).

Since I was out doing errands anyway, drove to town and bought a battery.  Had the laptop with me, just had removed the battery to replace it.  When I got home, I plugged in the laptop, connecting to the charger.  I wanted a full charge on the new battery.

Several days when I went to use the laptop, the machine did not boot.  Would not power up!  Plugged it in and ran OK.  Search the troubleshoot information.  The power like on the laptop was blinking - indicates a bad or no battery.

Called the local Interested battery store.  They reported that this is not uncommon.  Re-manufactured batteries may or may not run in my HP Laptop.  Made another trip to town for refund to exchange the battery.  Brought the laptop into the store to explain my problem.  The store clerk grabbed a different battery off the shelf - it works.

So, the bottom line - just because your laptop needs replacement, bring the machine with you and make sure the battery runs the laptop.  All replacement batteries are not equal!
