HP dv6700 Laptop Battery Issue

I have an HP dv6700 laptop which i was using almost day and night due to which the battery stopped getting charged, so i purchased a refurbished battery. First, this battery charged a little bit then stopped charging, it showed me "plugged in, not charging", but sometimes it was getting charged, so the charging kept going on and off. Then the vendor replaced the battery and it charged to 100%, but when i plugged out the adapter, it gave me only 3 minutes backup. when the pc was about to shutdown automatically due to lack of battery, the battery was showing 99% then in a second, there came a cross sign on the battery and the laptop shutdown.
When i restarted the laptop, it was showing 0% battery and charging. The charging seems to be normal but the discharging has an issue. During my experiments of checking the batttery, I also used different chargers/adapters but the result were the same. Sometimes charging the previous battery and sometimes not. Could anyone please tell me if there is an issue with the battery or may be with the charging socket (as someone told this to me as well)? In need of an urgent help. Thanking in anticipation.

I guess that its the charging circuits make sure you give the contacts a good clean on the battery and inside the laptop....

have you thought about getting a official battery instead of a referb?

If youve already concluded the laptop as bad and out of warranty you may wish to disassemble it and look for loose stuff around the power supply input and the battery contacts.

I just found this comment on http://www.laptop-batteries-shop.com/hp/dv6700_ct-battery.html when researching for this question -

When charging your HP dv6700/Ct notebook battery for the first time your computer may indicate that charging is complete after just 10 or 15 minutes. Dont worry, this is normal with rechargeable batteries. Just simply remove the HP dv6700/Ct battery from the laptop and repeat the charging procedure.

So it sounds like there could be known problem with this model of laptop.

Check your charger for buttons. HP has some chargers that will charge your battery to 100% then it will only trickle power as to not wear down your battery. When it goes into this mode your battery will completely drain but your laptop will still work while plugged in.

Look on the charger and see if there is a button with a small lightning bolt. If so press this button and it will light up orange. This is the charging mode.

My father had this problem, he took his laptop into Best Buy they replaced his battery and re-installed the OS. HP sent  a new battery. Then he sent it to me and I found the button.

You may need to calibrate the battery. Here is a link to the HP page explaining the procedure

Me and a24hrpc both stated in our comments that it might be worth replacing

"Have you thought about getting a official battery instead of a referb?"


"My father had this problem, he took his laptop into Best Buy they replaced his battery 

Surely he should give out some points for that and cant just close the question

Either#2, due to the authors reluctance to add feedback on the experts suggestions, until 5 days later  to inform us the problem was fixed.
or #4--> I would have to say ibexsystems comment hit the closest mark with the comment -->"have you thought about getting a official battery instead of a referb?"
 a24hrpc  danced around the battery replacement issue with his comments, but not in the context that that the battery was actually the problem, as the replacement battery in that case didn't work either, but that the button wasn't pushed to induce charging.
By the authors own comment-->"Then the vendor replaced the battery and it charged to 100%, but when i plugged out the adapter, it gave me only 3 minutes backup"
so even a second replacement battery was not working.(not often 2 batteries are DOA)
