Could not believe the price of the Fisher Price batteries. This one was half the price and works perfect , don't be afraid to try it. Thanks

The Tenergy replacement battery for the iRobot 400 series does not require much in the way of words to say that it works fine. It went right into my Roomba, it charged without incident, and I'm a happy camper because the daily animal fur explosion at my house is now under control again. I'm glad that the price has come down on these items, too.<a data-hook="product-link-linked" class="a-link-normal" href="/iRobot-Roomba-APS-4905-Battery/dp/B00022HZ04/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">iRobot Roomba APS 4905 Battery</a>

Its a battery - there is not much to it.  Appears to have come fully charged.  installed it into a Tripp-lite surge and battery back up device, replacing the OEM battery that lasted almost 6 years.

The battery seems to work fine, it doesn't seem to hold the charge as long as the original one, but I have no complaints.

I'm not an expert in the battery business but I really like this battery so I just decided to replace the battery rather than get a whole new case, etc. and it's doing what it's supposed to do ... my bit in creating a less cluttered landfill :)

it works
it is cheaper to replace the UPS battery instead of replacing the UPS

This is a "generic" version of the Black & Decker battery.  It is rated the same 2.0 Ah and came fully charged.
We used it this last weekend and it fit the trimmer well and lasted for the 15 minute trim job around our small lawn.
I will continue to use this battery until depletion to see if it has similar run time as the factory ones.
The price is rather better than the B&D genuine battery.

Hey, it worked for me. Its cheap and the battery has worked over the course of the year. It doesn't retain charge for too long, but solid nonetheless.

This is a real Samsung battery, but must be from an no old supply. The battery life is mediocre but for $8 it was worth it.

Received the battery and had no complaints. The price was significantly below what I had found elsewhere and the convenience made it a good purchase.

The battery on my HP Compaq nx9420 was dying quickly on me - it would only run the laptop for less than 10 minutes even after it was reportedly 100% charged in Windows XP. When I installed Windows 7 recently, I immediately started getting messages telling me that the battery should be replaced soon. Win7's ability to see what's happening with a battery is MUCH better than XP's.

I ordered this battery because it was low-cost and matched the OEM battery's power ratings - it's very important to be sure that the battery you are ordering provides the same amount of voltage as the existing battery or else your laptop could be permanently damaged. I had hoped to find a good price on a battery with higher total capacity (greater than 5200mAh), but this is the most bang for the buck.

The battery I received fits in my nx9420 very well but it fits significantly more snugly than my OEM battery. The ATC battery is one to two millimeters too large in one or more of its dimensions when compared to the OEM HP battery, but like I said, it does fit. It took a fair amount of force to get it to seat fully, but now that it is seated I know it's not going anywhere.

I've been testing the battery off and on for several months now and have had several hours of charge every time except for the first. When I initially plugged it in I let it charge for as long as the included note said to charge it, but when I turned it on after that length of time the battery did not last more than 30 minutes. I hoped it was a fluke and used the laptop unplugged until the battery was drained, then I turned on the laptop once or twice more to completely drain it. Then I plugged in the power cord again and let it charge for the time instructed once again and since then the charge provided at least three hours of power every time.

If not for the fact that the battery is slightly too large and had a temporary problem with holding a charge I would have given a five-star rating. Since those issues are minor or temporary, however, I did not feel that the rating should be less than four stars and if it was possible I'd give it 4.5 stars instead.

I ordered this battery to replace the original battery that came with my Dell XPS13 back in 2008. This battery doesn't fit exactly right (it's a bit tight), but I understand that this is to be expected because it is a generic replacement battery. I have followed the instructions of fully charging, then discharging a few times. After a couple of weeks it seems to work just fine.

This battery works just as we'll as the brand name battery and its a lot less expensing. I would highly recommend.

At this point in time the battery is doing OK.  Seems to have to be charged more frequently than an original
battery but this is satisfactory.

This is not the OEM battery pictured in the ad.  It seems to be a very good battery though, and it takes a charge, and works in the phone as it should, unlike the old battery I had in the phone, which wouldn't retain a charge, and kept giving me an error message, to move the phone closer to base, almost every time I tried to use it.
The only reason I didn't give it 5 stars, is because I was expecting a Panasonic OEM battery as pictured, but otherwise I am satisfied so far.

Does not last quite as long per charge as the OEM battery but the difference is not large. Most noticeable is that the charge indicator shows a low charge too early. If one ignores this, a near normal use per charge is possible.

reputable battery  very inexpensive compared to retail prices.
