756743-001 VI04 V104 Laptop Battery for HP Pavilion 15-P 17-F Series 15-p011na 15-p165sa 15-p214dx 15-p003ax 17-f115dx 17-f215dx Fit 756745-001 756744-001 756478-851 [4 Cells//14.8V/2800mAh/41Wh]

This is the 3rd aftermarket battery I’ve bought for this particular laptop. I’m still using an ‘older’ HP laptop, but it works for what I do ..and has an internal DVD Burner! LOL. The original HP battery lasted ~4-5yrs as I recall. Unfortunately HP doesn’t have a battery manager on my computer, so it pretty much sits at 100% full charge most of the time when it’s plugged in (which they say shortens battery life).The first aftermarket battery (exact same V104 battery as this), I bought from an auction site, and lasted about 2-1/2yrs. Some of that might have been my fault as the laptop would sit empty a few times when I was on vacation. Now I always remove the battery if I go on vacation, etc.The 2nd aftermarket V104 battery (same Amazon seller as my most recent replacement battery), failed real quick like in 4-5 months. That was odd. It just died, nothing that happened out of the ordinary…I just one day ‘died’. I didn’t try to warranty it out. But in all honestly I completely forgot to do any ‘conditioning’ when I installed it. I’m thinking something internal gave up.The last (3rd) V104 aftermarket battery, I bought from this seller, lasted 3 1/2 yrs which I’ll call ‘decent’. Recently it just up and ‘died’ …no slow death or gradual weakening capacity — just died a week ago. That battery I DID follow the ‘conditioning’ instructions included with the battery to a ‘T’. Even though some say it’s not needed with modern LI-ION cells…I did it anyway. Who knows what battery chemistry they’re using. I was a lot more careful in the last couple yrs not to let the previous battery run down completely and charge properly, although ..life does happen and admittedly there were a couple instances where the laptop did run out of juice due to inattention. I’d like to get 4 yrs out of a battery, but 3 1/2 I’ll take.I’m currently “conditioning” this new battery which I received promptly from Amazon. Conditioning per the included instructions. Weather it’s truly needed or not, IDK. Hopefully (fingers crossed) ….maybe I “Can” eek 4 yrs of life out of this battery. I might not even have this laptop in 4yrs. BTW the fit and finish compared to the original HP battery for a older HP Envy laptop is spot-on-perfect from what I can tell. Hope it helps. If your computer has a battery charge limiter where you can set a max charge (say 80%) you might get even more life than I did. Fortunately the price of these is reasonable.Cheers!
