Great alternative to an OEM battery
926177
I've been using this battery for about 6 weeks and so far it lives up to the previous reviews high marks.  Lasts longer then the original battery (not by a lot, but better then any other replacement laptop battery I've used).

To sum up: Great price, perfect fit, and longer life. I recommend purchasing.

Good replacement for Sony OEM battery. Takes a little longer to charge, but works well.

I was Leary of purchasing a no name battery. Once it arrived I immediately compared it to the original and found the specs matched as well as the shape and sizing.
Once installed I did an initial Bios battery calibration and have had no problems since install.
I would recommend this as an alternative to high priced factory replacements.

WORKS LIKE THE ORIGINAL BATTERY, AWESOME. I HAVE RE-CHARGED ABOUT 50 TIMES SO FAR WITH NO LOSS OF CAPACITY YET.

After a week or three of using the battery, it seems to be a fine replacement for the OEM one.  It fits perfectly, and holds a charge very nicely.

This battery is definitely worth the money.  Fits perfectly into my mac.  Battery lasts approximately 3 or 4 hours, which seems comparable to the battery life of the original apple battery.  Had previously purchased a battery from another seller for around $25, the battery didn't fit and didn't last more than 30 minutes.  This battery is a perfect alternative, costs a little more, works substantially better, and doesn't cost as much as a battery from Apple.

The battery was packaged well and arrived promptly!

So I'm always wary of non-oem replacement products,  especially batteries,  but this battery really did the trick! My laptop battery had been slowly degrading for a while until one day I couldn't even unplug my laptop without it turning off instantly. I wasn't sure that I was going to replace it (remembering the last time I bought a replacement battery for $80), but with this being so cheap, I thought I would give it a shot before I decided to buy a new laptop.

As it turns out, this battery is excellent! It lasts about 2.5 to 3 hours in my laptop which is similar or better than the OEM battery. Plus this battery has a push-button charge indicator -- something the original didn't have. Definitely worth the ~$15 I paid.

This battery is a life saver. My OEM battery for my Note 4 had seen better days. I was often needing to charge it after I got home from work because I was at 15 or 20%. With the new battery, I have been at over 50% at the same time with similar usage. Fits like original, charges like original (or faster) and overall is a solid replacement battery.

If the first charge is any sign of the quality of this battery, I'd say it is a winner. My original battery didn't last 6 months and I don't remember the first charge lasting over 24 hours with mild to heavy use like this one, thank god for the ability to change batteries. I am skeptical that this is a true OEM battery, where the labeling was someone different, but we'll see.

Much cheaper than buying a replacement battery directly from Verizon.  Actually, I think it was about half the cost.  I'm glad I checked to see if there was an alternative to purchasing the battery elsewhere. Works fine and does the job it is intended to do.

Solid replacement at a decent price for the OEM dell laptop E5240.  Following the burn-in period religiously for full charge to full drain at least 10 times, I'm getting a solid 4 hours of charge when on battery.  Most of the time this laptop is docked, and when it is, I remove this battery to ensure it lasts longer than the laptop does.

The product was shipped fast and was sensibly packaged in a "frustration free" manner.  The look was a lot more high end than I expected for a simple battery.  But its a battery, so it gave me a little more comfort that it won't be a unit that flames out, or dies out.

Way better cost option than original batteries - and it works just as well

Great replacement battery ... easy to install.

The promise of a few more mAh out of a battery seems to make it a plus over the OEM battery. From either the Canon battery or this one, I wasn't burning through a complete charge in 3 hours of U/W photography, maybe I don't shoot much? It was way cheaper than the OEM anyway, so no complaints.

This is a great replacement battery. Aftermarket batteries always make me a little curious so this one i did a test with. I disassembled it and looked at the individual cells that make it up. While they are not name brand cells, they are some Chinese brand. They all did test well over 2000mAh which is spot on where they should be.

I received this product at a discount in exchange for my honest review.

Works as expected. Holds charge very well. I can't tell a difference between this and the OEM battery.  Would definitely buy again.
