Good battery saving replacement, bad product description
935574
The bulb works well. It should help save battery power which is the big thing for me. So I expect my light to last quite a bit longer per set of batteries vs the original incandescent bulbs. As to the brightness, it is only as bright as the original bulbs, maybe even a bit more dim. Was hoping for better in that area.

Finally, the current description says pack of 2, that is a lie...I received one bulb. Not sure what they mean when they state "Pack of 2".

It's OK, so far (I'm currently trying out all of the features), but the Amazon heading is misleading. The photo shows two batteries, and the description reads "Extra Bttery".

I only got one battery.

If anything changes, like superb video quality, or an extra battery arrives on my door, I'll up my rating.

I hope the seller corrects the "Features" and "Description" that still appear as of this writing.  If so, you won't know what I'm complaining about and all will be fine.  Order the T-Shirt.  It's great!  You may also need to order two CR2032 batteries.  Depends on whether the seller reads this.  This review applies to all sizes in all categories.  I hope I can revise my review if/when the listings are fixed.

The shirt is great.  Programming the scrolling message badge can be tricky if the message is long, but is do-able.  For long messages, I suggest finding a glass table (or flat piece of sturdy glass) and placing a mirror underneath to see and select the right letters without timing out and having to begin again.  The half-sheet User's Manual is poorly translated into English.  I'd help them write one easier to follow but will wait 'til I'm less frustrated with their responses in our many emailed interchanges:

This badge requires 2 flat round CR2032 batteries that neatly slip into the rear, NOT the 4 AAA batteries they list under "Features" no matter how many times or how emphatically they may insist.  Why they list batteries neither included nor necessary remains a mystery to me.  Explained this to them when I asked why the battery they advertised wasn't included.  I didn't mind buying the two little batteries.  Knowing at the start would have gotten my gift to its recipient in time.  They have advertising choices to keep their listings from being deceptive: replace the incorrect line about the unnecessary triple A's with: "Requires two CR2032 batteries (not included)" and remove all reference to including a battery at the end of their Product Description or correct the ad and include the batteries.  Either would have been fine with me.

A nice product with good battery life and features, but I think the LCD monitor/display functions were over-hyped in the product description - made it seem more clever than it is and by implication what one should select over the simpler model.  Actual performance comparison data (charging time, battery life, etc) for their several charges would be nice.  It would be more convenient for travel without such a long cord.

Somewhat deceptive product....much less capacity (about 15-18%) than a GENUINE Apple replacement battery (6000 MAh vs 6900 MAh).  The software in the battery is programmed to the lower capacity so it doesn't trigger a "replace battery" notice from the OS, but the run time is much less than a genuine Apple replacement.

Giving it 3-stars from the start as I have not been able to use it.  Reason?  The other reviewers are correct in that the charger that comes in the box is the LCS436, a slower charger, which in my internet searches lends me to believe that it has been discontinued.  The item description needs to be changed to reflect this.  The great thing is that it DOES include the better 2.0Ah LBX2040 battery which is the better-rated battery than the standard LBXR36 that comes with just the trimmer that's only $6 less.

To be honest, I just bought the set to get the charger and battery for a lost battery and charger for a LHT2436 Hedge Trimmer I have received.  After pricing it out, it's a better value than to just purchase a battery and charger separately.  Amazon's customer service was great when I called about the charger issue, as they refunded me the cost of the correct charger which allowed me to get it for free.

Once I actually get to use it, I shall update this review to reflect my overall score.

Just got my S90, with the Canon 1000mAh battery.  Ordered these aftermarket batteries as spares from seller "thememstore", but they substituted a Power2000 battery, which says 1200mAh on the label.

I ran endurance tests (shot video for as long as it could) on the Canon and "thememstore" batteries.  Result:  these "thememstore" batteries have only about 61% of the capacity of the Canon battery, even though they should have 120%.

I have bought other batteries for other cameras from "thememstore", and they also substituted a different brand than was advertised.  I haven't rigorously checked those, but they also didn't seem to have as much life as expected.

This is my underwater SCUBA camera, so I need the batteries to last through a couple of dives -- these obviously will not.

Update:

Thought I would add this:  After a while, both this and a seemingly identical battery with another knockoff label have become very difficult to insert and remove -- they have both puffed up a bit like a pillow.  Makes me concerned that some gas pressure or something is building up, and I might get one of those lithium battery fires -- the ones that made Apple phones have batteries that are no longer replaceable by the user, so that they don't get sued for someone's counterfeit "Apple" battery.

This battery fits my 10.6" Acer Aspire One (A0751h-1545) replacing a UM09B34 OEM battery. Charged and is working fine.  Warning: This battery's capacity is advertised in the product description as 5200 mAh - After I installed it in my system, It reports a max capacity of only 4400 mAh  (48.8 W/hr @ 11.1V = 4400 mAh).  I purchased this battery based on the extra capacity touted in the product description, so I'm not very happy with this battery.

Listing claims that the batteries "meet or exceed OEM specs", this is clearly a lie as is the mAh rating of the batteries as they last even less than the OEM ones, but a crappy backup battery is better than no backup battery.

I am completely dumbfounded that they include a microfiber cloth which I have a million of because everything seems to need to include one now and days, but threy cannot include a $1 110v AC adapter for the USB charger.... Comon....

This is a frustrating listing!  I need to replace the remote for the older style with 4 dip switches, which this listing appears to be.  It even states it has a 9 volt battery like the older style.  Unfortunately this is the new style with the learn button and AAA batteries.  Partially my fault for opening the packaging before I realized this but the product description is incorrect too.  In fact it's incorrect in two spots, first where it lists a 9v battery is required in the description and then again in the product specification where is listed a 12 V battery.  Also the style number on this listing doesn't match the style number I received so beware if you're trying to replace an existing remote.  I'm sure if you're installing a new kit it's fine.  But on my 20 foot vaulted ceilings I'd really like to avoid that since all I need is a new remote.

I needed replacement batteries for a Viore 7" Portable HDTV (PLC7V96) - could not find the actual batteries by the name or number on them, so I had to order by size.  I ordered the 406080 battery two pack, and these 2200mAh batteries are actually a bit smaller than the original 1800mAh batteries!  The actual measurement of the 406080P batteries I received are: 3.96mm x 54.3mm x 81.9mm.

I have only had the new batteries in for one day, but so far they work perfectly - the originals were rated to power the TV for up to 1.5 hours, and these just ran 2.0 hours.  The batteries came very quick and were exactly what I ordered.  One arrived with a full charge of 4.03V, and the other was down to 3.87V, but they both charged up just fine in the TV.

Just a note on the installation - obviously I wired these up exactly like the originals, and they ARE connected in series.  The original plug is a three pin connection, with the negative from one battery to the black wire, the positive from the other battery to the red wire, and the series connection between the two batteries connected together to the middle white wire.  There is no reason why this should have been a concern, since that is the way the TV was designed, but I saw the question where the answer said they could not be connected in series, so I thought I would comment on it.  The attached wires on these new batteries are MUCH smaller than the ones on the original batteries, but I assumed that they had to be big enough for the rated power of the batteries, so I just spliced them into the larger wires on the original plug and powered it up.

One last comment in case anyone stumbles on this review for the same TV - once the batteries have been disconnected from the main board, the TV will NOT turn on again under battery power until the charge cord is connected the first time - this is true with the original batteries and these new ones.  I do not know why it is like this, but after connecting the cord and powering the TV on once, then it works fine on the batteries after that.

UPDATE:

TLDR; version: false asvertising, actual capacity 50% of the claimed 2500mAh, excellent customer service

Full version:

Powerextra has a very quick customer service, they contacted me almost immediately and sent me one replacement battery for testing. Initially, my test plan was to use a B&D Matrix circular saw attachment and cut wood panels until battery is depleted; do this with this new one and my old 1.5Ah B&D battery and compare total cut lengths. This would make a more or less "scientific" comparison.

Unfortunately, due to how easy it cuts 0.5in. particle board (like butter) I needed to cut, I finished what I needed to do before running out of battery. So, I wondered if these batteries simply have 18650 type Li-ion cells inside? First, I opened the original B&D battery (just four T10 screws) - and tada! inside are just five 18650 cells in a holder and a stamp-sized controller PCB. The cells didn't have any markings on the exposed side, however, and I didn't want to tear it down more and end up with a broken battery to find out.

Then, I opened one of the Powerextra batteries from my order. Inside were five LGDAHA11865 18650 1300mAh cells, so total capacity is 5*3.7V*1.3Ah=24Wh, half of the claimed 50Wh, and less than 30Wh of the OEM B&D battery. Perfectly in line with my intuitive guess based on actual use that it seemed to be about 1.0Ah, not 2.5Ah. My estimate was off only by 20%, actual capacity 1.2Ah, 24Wh.

Lastly, I opened the replacement battery, it had fiveICR18650P 1500mAh cells, slightly better, total about 28Wh (1.4Ah), almost like the original 1.5Ah, but again, far from the claimed 2.5Ah. This 1400mAh battery, I guess, is the "(Upgraded) Powerextra 2 Pack 20v 2500mah" version you can see in the new listing.

Powerextra generously offered me $5 as an apology; instead, I opted for another replacement battery to bring the total capacity I received to 100Wh as it was advertised (2-pack of unobtanium 50Wh batteries; instead, I get a 4-pack of obtanium ~25Wh batteries).

Zero stars for false advertising; one star for great customer service.

Original review:

Nowhere near the claimed 2.5Ah. I have a 5y.o. original 1.5Ah B&D battery with hundreds of cycles and it still lasts significantly longer than these. These, empirically, seem to be like 1.0Ah. Hence, 2 stars (1.0/2.5 = 2/5).

Works fine as a replacement battery.
However, the description says, "Replaces 14.4 Black & Decker Firestorm Battery PS140"
I have several of the Firestorm power tools and the battery is NOT a replacement without modification.
There is a raised bead/edge around base. (The edge that touches up to the tool, where the seam is.)
This raised edge has to be ground off in order for the battery to fit correctly into the Firestorm tools.
All other aspects work just fine.
However if the price is right I would buy again.

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.

The battery is fine but I ended up buying a lessor Mah, i.e., 1800 rather than a 2100 Mah, because the Mah rating was not disclosed in the information.  So I was somewhat disappointed in that.  I am giving the item only 3 stars  because of the lack of information on the web site.  One could argue that I was not forced to buy a battery when not sure of size in Mah.

What a difference a good battery makes.  Even though it's only 18 months old my wife's iPhone 6 had horrible battery life.  Sometimes.  Randomly a full charge would last her either all day or only two hours and we couldn't find a pattern.  I installed an app that reports the battery's actual capacity and that showed just how inconsistent it was.  Sometimes a full charge (100% on the upper-right battery meter) would be 1400mAh, other times it would be 700mAh.  Clearly the battery was flaky and after 950+ cycles that wasn't a surprise.

I installed this battery in her phone and there's no more shutting down when the battery icon still said 25%; no more dropping from 80% to 20% in the span of 10 minutes. It's almost like new again.  Why "almost"?  Because a full charge of this battery is 1751mAh, not the 1810mAh advertised.  That's less than 4% difference so I'm only docking it one star but be aware it doesn't hold as much as they say, or as a stock battery does.

One word of warning for the installer:  Be careful when removing the old battery - it's easy to nick the ribbon cable for the power switch/flash/volume buttons, like I did.  Then you'll be buying&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/one-of-these/dp/B00XHWWXYO/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">one of these</a>&nbsp;and you have a much bigger job ahead of you than replacing the battery.  It's not hard to do it right as long as you're careful.  I'll know for next time.

Functional, uses regular batteries, though its complicated with steep learning curve
