HSX 2800mAh VI04 Laptop Battery for HP 756743-001 756745-001 756744-001 756478-851 ProBook 440 G2 450 G2 756478-421 756478-421 756478-422 Envy 14 15 17 – High Performance [4 Cells/2800mAh/41Wh]

The battery was a good fit and fully charged to 100% BUT when I verified the battery on the standard HP battery tester app, the app came back with no battery installed The NSX battery was sent again, and it did the same thing as the first. Since the original, this is the first time I've had to replace a battery. Originally, the charge OFF adaptor lasted over 6 years, but in recent months, it has only lasted about 10 months. 15 mins. I returned both to the manufacturer for a refund, and I'm still looking for a battery that works AND can be tested. Overall, the quality appeared to be good, but I'm not interested if I can't test it.

My laptop is old, and HP does not have any of these batteries in stock, so the battery on my computer died completely. This option was available on Amazon, and it was delivered to me in just two days! It fit perfectly, charged quickly, and gave my computer about 3 hours of battery life, which isn't quite as good as when it was new but certainly better than before. Because I just installed the battery, I can't say how long it will last, but it doesn't have to last very long to be worth the money at $28.

This battery has been charged to 80% of its capacity. It took about an hour to charge it completely. I usually avoid quick-charge batteries because they don't last very long. I recharged the battery by running it to 2010% again. The run time is approximately correct, 2 hours for a 2200 mA battery and 2 hours and 30 minutes for a 2800 mA battery. Although it stated that it contained a grade A battery, no Samsung batteries were used.

So far, there have been no problems with the plug and play method. I haven't had much opportunity to use it off the charger, but when I have, it has held a charge well. Others would benefit from it.

The battery is functional, but it does not appear to hold a charge as well as the previous one. It's not going to last long, I'm afraid.

If I have no recollection of it, it must have gone well. When it comes to batteries, this is a good thing.

It fits perfectly and lasts as long as or longer than the original laptop. The product was delivered the next day and was simple to set up.

I bought this battery to replace an OEM battery that had failed. Both batteries have a capacity of 2800mAH and a capacity of 41 Wh. The OEM battery has a life expectancy of two years. In between charges, you can spend up to 25 hours surfing the web. This battery lasted only about an hour when the display was turned on and no apps were running. I returned it for a full refund, of course. If you expect OEM performance, I wouldn't recommend purchasing this item.
