342569
HORRIBLE!  I purchases this as a backup as I travel a lot.  Battery physically EXPANDED ON THE FIRST CHARGE!!!  It is warped and completely garbage.  I'm throwing away this and the second battery that I purchases for my spouse.  I will not buy another product from this vendor

These (I guess) after market batteries are just plain garbage and an awful waste of resources. Don't buy. I bought two. The first never charged and I returned it for full refund. The second worked for a few weeks but now only charges to ~50% capacity, with further decreasing tendency. And I didn't even use it much. The rubber foot attached to it (to become one of the laptops rubber feet) fell off immediately when I first unpacked it. I am contemplating to dispose of it for fear that one day it might cause damage to the laptop. Awful junk. Should be taken off the market immediately.

I have a Toshiba L675 and my original battery about 10 years old was providing only 45 min of run time This battery was supposed to extend that to 2 hrs I bought battery on Aug 1st (today is 9/16) I installed the new battery and followed the proceed o discharging the battery and recharging 4 times Initially I was getting 1 hr 40 minutes but seemly with each utilization the run time became less and less now it's down to about 40 minutes It's preforming worse then my 10 year old original battery from Toshiba For me this product was a waste of money deceptively advertised and typical of the lack of integrity and product quality that has become synonymous with Made In China To put it in the vernacular o the streets another Chinese made "Rip Off"

Garbage. Only worked for one charge which was only about 6 hours. Never worked after that.

This is more crap from China.  I bought this battery as a backup battery for my 17" macbook pro.  I thought I would save some money over the Apple OEM battery.  I used and recharged the battery about 6 times and now the battery icon say REPLACE NOW.  The battery will not charge at all, even though it shows a green light on back.

The description says METALLIC, the only thing metallic about it is the COLOR.  This battery is PLASTIC.

I think in china they just make something that LOOKS LIKE a Macbook Pro battery and fits inside a macbook pro, but I'll bet if I open it up its full of crappy AAA batteries.  AVOID AT ALL COSTS unless you feel like just giving away $50 to some guy in china.  I can't imagine this cost them more than $2 to make.

I tried contacting the seller but I get no reply.  DO NOT BUY THIS CHINESE JUNK IT DOES NOT WORK!!!

upgraded from one star to two, since this may not have happened to everyone who bought this item.  got the battery and it fits my studio 1745, but does not charge.  came with 67% charge.  I tried unplugging the laptop to see if draining the battery some would prompt it to charge, but no go.  Also, it drains incredibly fast.  at 67%, my computer indicated the charge would last only 1 hr 8 minutes.  had it unplugged for about 10 minutes, maybe less and it dropped to 47%.

Maybe it's just from a bad batch.

Now I have to go to the hassle of returning it and shopping for a new battery for my laptop.

I plugged this in for the initial charge and the whole thing started swelling up within 10 minutes... I unplugged it and its going in the trash. <<< not worth my time to return.

Updated:  Initially rated one star for the reasons stated below.  Have revised to provide a more neutral rating.  While product was defective, Amazon did provide a prompt refund without me having to jump through a lot of hoops.  After the initial disappointment that I couldn't spend likely the last nice fall day on my bike, the situation has been resolved reasonably considering batteries are sometimes defective.  Main concern was initially thinking there was no simple way to resolve this.

Battery was strong and fine at installation.  Tested as fully charged.  However, battery will now not hold a charge despite being on a battery tender.  Battery lasted only a month which is through the return period but it is now worthless.  Avoid this seller and this product if they will not make good on their product.

1775mAh is a false advertisement. Ih has less then a half of the capacity of the original battery.
Avoid this product.

Would not charge after two uses. I left it on that junky charging cradle for a full day and got 30 min of battery life.
The worst is that there's NO WARNING on battery life. One call of "low battery" and then it shuts off. Lovely If you've just started in on your run.

The charging cradle is ridiculously flimsy and junky. Sony is trying to make money by having a distinct charger instead of a universal micro USB, and you can tell how poor quality it is.
Returning these. Possibly going to try another pair but unless I see that my first pair was specifically defective I will hold the review.

Battery dead after a month. Bought new battery, then instead of booting OS, battery icon with red X appear on display. Throwing into Garbage right now.

this is a complete piece of garbage.  The first time I plugged it in, I did get the indicator lights described in the booklet and my battery charged.....really slowly.  As in, overnight wasn't long enough for a full charge.  Yes I aligned the pins according to the instructions and confirmed that the battery was in the right position.

The second time I got a flash of blue from the indicator light, but no red light indicating it recognized a battery that needs to be charged.  It's hard to tell whether it's broken at the wall socket where the power comes into the device from the wobbly articulating plugs, or that it's getting power but can deliver it to the pins.  Now I cannot get it to register that a battery is in it at all, and of course it won't charge anything.

So pissed. Have a brand new fuchsia vape and brand new batteries. Got this to charge )first time ever having to charge) bc was told not to use USB and first I was having issues with the it not charging. Stayed flashing bottom line for over an hour until I realized I had to click the side button a few times bc it did NOT recognize the battery like it said it would. Then let it charge overnight about 8hrs. Said both were fully charged but when I put in my vape it only gave 3/4 battery life. Worked for about 5-10puffs then got an error message on my vape saying the batteries were imbalance. Those are brand new batteries, never charged before and now ruined because of this charger. Submitted for return and when picked up all I heard something rolling around inside. So not sure if was damaged in route or sent me a defective one but I'm upset that this charger just cost me an extra $30 bc it ruined my batteries!

The charge was poor.
The battery didn't stay on the phone well and is susceptible to damaging the connector on the phone.
It's bulky and inconvenient to carry.
One day it decided to expand and broke the outer case. I'm lucky that it didn't explode.
Avoid this at all costs.

I have had this battery for less than 6 months and the 1st time i unplug it from the charger and use it on just the battery power for 15 minutes,the battery will constantly charge and stay at 98% so now i have  to unplug the laptop after i turn it off so it will not keep trying to charge this defective battery.

The first full charge didn't last more than 4 days with the wireless off.

I figured that the battery would need a few recharge cycles, and then I would get that 2-week lifespan everyone else was raving about.

No.

It just got worse. After 6 months I must recharge it after 72 hours, and that's if it's turned completely off. If reading, I must plug it in every 48 hours.

I'll be contacting Amazon over this, but I'm probably just screwed.

I don't have good experience with aftermarket batteries - quality varies considerably, even among samples from the same manufacturer. It appears that Amazon's quality control on batteries for these devices let at least one bad one through.

I have few other complaints: the refresh rate for turning pages is too slow, and the placement of the USB jack, which I have a lot of experience using while reading, makes charging awkward if you want to keep reading. On the positive side, this is a fine device for reading, with a clear screen that is easy on the eyes. After a few minutes, I no longer noticed I was using an electronic device instead of a book.

This product is garbage.  A full case charge only recharges the phone to 40%.  The internal battery of the Moto G 1st gen is only 2000 mAh.  A quick look inside the battery case reveals a 1000 mAh LiPo, not the 3500 mAh advertised.  Don't bother!
