New Laptop Battery Not Charging.

[Turk]

Howdy,

I got a new replacement Laptop Battery for my HP DV6700 series computer.

Put it in a couple days ago and it said 67% available, charging.

Well, I just looked at it and it still says 67% available, charging.

The original battery would drain rather quickly, so I got this one off Amazon:

Think it's the battery? Or the charger?

Anything I can do to diagnose?

Thanks!

I'm going to assume that for $15.45 that's not a genuine HP battery. I have had mixed (mostly poor) results with non-OEM batteries, both in my phones and in laptops. Someone with more knowledge than me will chime in here I'm sure, but I going to guess it might be the battery.

I think it's the fact it cost $15.45.

Quick update:

I unplugged it and within 30 seconds, I got a pop-up to plug in the Laptop, as the battery is at 6%.

Several minutes later, it's STILL at 6%.

The blue light at the connector is on & blue, btw...

I put the original back in and it charges & drains normally.

Bad Battery.

Try making sure your BIOS is up to date before sending the battery back.

I went through this with a refurb HP/Compaq from Newegg-- came with a complete turkey battery. Got a cheapie off amazon and it worked perfectly. However the BIOS flash was also suggested.

There's some sort of "telemetry" going on between computer and battery.

But of course if the BIOS flash doesn't work, send it back, make them deal.

The original that's back in drains & charges normally.

The BIOS not being up-to-date doesn't apply with this information now, correct?

+1. It probably needs a handshake between the BMS and the charging circuit that this laptop has setup and others perhaps don't.

Or else a bad cell, etc.

Li-ion have bad enough failure modes that Id not trust a $15 battery in my home. 18650 cells are around $5 each, +/-, and to get to 10.8V you need three or more, plus some in parallel. Doesn't leave room even for Chinese labor. Thus Ill bet these are recycled cells.

Yuck, yuck, yuck.

Return and get a proper one. HP buys/uses some really high quality cells in their better packs (same ones apple uses).

 

[Turk]

Yep, I'm returning it to Amazon.

Pfffft. What a bummer.

just ebay a "genuine" one

I've had better luck with these than the 19.99 generic chinese with recycled cells

ebay hp battery

It doesn't make sense to me either, but was suggested by professor Bing when I was trying to figure it out.

 

[Subdued]

actually is does.

The battery has a firmware like everything else in the computer. If the BIOS isn't sure how to "talk" to this firmware, you're going to get odd happenings.

a BIOS update can address this.
