Good Value Replacement Battery
OEM fit for my HP ProBook 4540s. I have gone through over 20 recharges without a hitch. Getting about 3.5 to 4 hours of usage after recharge.
Amazon Customer –
Works great, do not bother with other brands.
So i tried to buy some used oem batteries from the strore for my hp laptop and had to return both of them, i guess all oem hp batteries are too old, and also another extended battery i got lasted only a year until it got swollen for no reason and charged only to 75 percent. I was going to get rid of the 8440p laptop sinceIt was old but wanted to give it one more try. This battery charged to 100 percent and lasted very long. It is the best aftermarket HP battery that can be bough. 5 stars for now, if anything changed within a year i will update my review.

What ever happened to really good replacement cells?
This is the 5th battery I’ve been through on this laptop! They last me between 2 and 3 years.Yeah, I know that, technologically speaking, my 11 year old dinosaur of a monster HP 17.3″ laptop is ready for the trash heap.* I know that I’ve tricked it out with software, memory, SSDs, extra cooling and other stuff that’ll bog it down and use up juice.* I love the fact that the battery releases with simply the flick of a latch that releases it for replacement. (And with a flick of the latch in the other direction – voila – the case is open giving you painless access to all HDD & SSD bays, chips, etc!)* I know it’s old enough that finding ANY battery for it is a good thing.BUT – why are all (the few) batteries out there basically crap when it comes to runtime? From the first time I had to replace the battery in the laptop, the batteries have gotten worse and worse in actual MAh. Each one claims to be a bigger capacity but in fact they have gotten progressively worse with each new replacement battery. This one’s no exception.Original battery (this is a 12 cell battery) gave me nearly 12 hours of runtime doing the usual desktop type stuff. Next one a bit less and so-on down to this one. Down to about 2 to 3 hours!Maybe it’s inferior cells? Maybe it’s the computer taking more energy!? Maybe its a basic scam in that the cells are simply not as robust quality?Bottom line: I’m OK with this battery because my options are so few, and I guess I’m happy to even have an option. I do think that If there’s a next time (my average has been about 2 years per battery pack), I might just go with the cheapest thing out there.Or, maybe I’ll finally do what I have threatened to do for years – cut the damn thing open and replace the cells with good Japanese high quality cells! The cost of that might well compel me to get a new laptop for sure. And, it might be moot because the last battery I tried to crack open to inspect and suss out, needed to be destroyed in order to open it up! And I really hate using a cutting torch on a container of Lithium Ion batteries!!Ah, the joys of holding onto things beyond their time …Now I’m probably going to start to have issues buying body parts for ’63 Rambler American!!

EXCELLENT !
I ordered this battery 4 years ago and been using it with my laptop on daily basses. Maybe I shouldn’t keep the laptop still plugged in with the battery on to prolong its life, but I do … At this point, the battery by itself without watching videos and not being plugged in, can run the laptop for almost 2 hours.

working good 6months
Sometimes when you buy a third party rechargeable battery such as this they are junk and last only a few weeks. Not so here. I have had this battery six months and it is working fine. I don’t know if it will last two years but so far at six months it is looking good.

Good Business
NinjaBatt is good to do business with. Iâve purchased batteries for 2 different laptops. Both worked great! I also ordered the wrong size on one, my fault, and got a quick return and credit. Thanks NinjaBatt!
