5 Stars Decent for the money
Not as good as Canon, but for the money this will work great for a backup battery! I would say it lasts about 75% as long, and have not had any problems with it.

1 Star The marked voltage worries me a great deal
The Canon Xsi ships with, and is rated for, a 7.4v battery. This is listed as 7.2v on the box, the battery and on the Opteka website. I was told by a Marketplace Vendor that the 7.2v is a “misprint,” but there is no way of truly knowing and it’s enough to make me worry. I’d hate to damage a $$$$ camera over a $ battery. This one is going in the garbage and I’m going with the Canon Equivalent LP-E5 Battery which is marked with the correct information (7.4v!), has a solid reputation, and is currently selling for a better-than-amazon price on Diamondback Battery’s website.

5 Stars Better than I expected
Been using this battery now for over 3 months with my T1i.

Holds its charge a looong time. I haven’t timed it, but it feels at least twice as long as the standard battery.

…and you can’t beat the price.

Advice: if you’re looking to get an extra battery, get this one.

5 Stars Works just fine – excellent value
Having a new camera for taking pictures of museum artifacts (primarily), I needed spare batteries to “feed my flash.” Problem was that the OEM battery (Canon) was ~$70 USD each which would reduce the number of spares I could pack. Also, the OEM charger was AC only, so would not allow for recharging while in transit. Opteka to the rescue! Inexpensive batteries and a dual AC & DC charger fit my needs exactly. I used the batteries for all day shooting of museum aircraft (lots of flash usage) and they performed at least as well as the OEM battery. Recharging was quick also, being less than 90 minutes in the car, so I could always have charged batteries on hand. Excellent value and performance overall, highly recommended for the amateur photog, perhaps even for the pro. Didn’t try the Opteka batteries in the Canon wall-charger as I was the Opteka charger, so cannot comment on capability. I recommend the charger & battery combination anyway because of the DC car plug.

2 Stars got what you paid for
Fully charged it after some use of it already and seems as if it has the memory effect. The XSi camera’s battery icon shows it has at least half of the juice left before the camera stops working. Well, you trade 1/2 of the battery capacity for 3/4 of the cost. A good deal? In the shooting field, you may have twice the chance to have to change the battery at that monemt you wish you were not, like I was. Not sure if other 3rd party batteries more or less the same issue…..

5 Stars A good original Nikon product
My Nikon EN-EL4a battery is used in a Nikon D3 body. I actually have three of these batteries, but to be honest, I’ve never even had to switch over to the first backup unit during any of my shoots. My EN-EL4a’s will not quite reach the number of shots as advertised by Nikon, but I easily get over 1000 shots with my auto-focus lenses attached and shooting mostly in manual mode.

There is a bit of a premium to pay for this original Nikon product, but I would not use any of the 3rd party units on my really expensive D3 body and risk the possibility of damage to the delicate electronics.

5 Stars Best nikon battery
By far a superior battery. Charges very well lasts for thousands of shots in Raw mode.

5 Stars Another great deal from Amazon, less than $100 for EN-EL4
I looked high and low for a good deal on the Nikon EL-EL4 battery. I sent for a “knock-off” for 54 dollars. Bad idea, it didn’t even work so I sent it back. Amazon finds me the genuine Nikon battery for less than $100! Got it in 2 days, like usual for Amazon, and popped it in my D300 camera (with my BL-3 battery cover which I also got from Amazon for cheap) and now I get 8 frames per second. Amazon is simply the best, and fast.

5 Stars Very Impressive
When I purchased my D3x I also bought 2 of these as extra backup. After using my D3x extensively in Greece I found I really didn’t need the extra batteries. On one charge I was taking 700+ photos per day casual shooting and I still had 75% charge left!!! This battery is quite amazing. I calibrated all three during charging and the accuracy is impressive, along with the information display of the number of shots taken on a charge. Highly recommend the quality and performance.

5 Stars Works with my film camera as well
I bought the battery, along with the associated charger and battery cover to work with my MB-40 on my Nikon F6. Unfortunately, I had to order it through B&H since Amazon.com wouldn’t ship the charger to Hawaii (seems no one has clued Amazon that HAWAII is part of the US).

5 Stars Perfect battery clone!
Holds the charge for ever. Fits the Canon Rebel XSi perfectly (just like the original batter). Excellent option over the pricey Canon one.

5 Stars Opteka LP-E5
Bought this as an additional battery for my Canon Xsi, the extra charger was just a bonus but a bonus that turned out to be even better then expected, not only is it an AC charger but also comes with the vehicle charger adaptor as well as the universal charger adaptor for over-seas.

4 Stars Works great
I bought this for a new Canon T1i and it works great. The car charger is a nice touch. I can’t say that it lasts twice as long as the Canon battery, but it lasts at least as long.

5 Stars Same as Nikon
I got this so I would have an extra battery for my Nikon D90. It looks and feels just like the Nikon battery; just a different color and lower price (and I did get a cover with mine). I used it after I charged it up overnight in the Nikon charger and it took over 400 pictures with an auto-focus, vibration-reduction lens and still had a little power left over. I recharged it and it did not get hot while recharging. I can’t say it is better than a Nikon battery, but I will say it’s just as good. Shipping was quick and the packaging was adequate. I can recommend this battery.

5 Stars Excellent battery
Inexpencive replacement battery. Everything works fine, the camera recognizes it, shows the charge, it holds out as long as the Nikon equivelant.

i would reccommend this.

4 Stars Excellent battery
I usually go for OEM accessories. But having spent 1100+ already on my D90, I thought I’ll take a chance with this battery. It turned out to be really worth it. As other reviewers have noted here the only difference I could find between this and the original Nikon battery is the label and an occasional twitch when inserting the battery into the camera. Used it to take hundreds of pictures on a single charge. Only when I used flash I had to wait for sometimes for the next shot. This happened with the original battery too.

5 Stars Completely Satisfied
Yes! Go ahead and purchase this battery! If you are reading this review and you are not sure if an off-brand battery is worth buying, let me be the one to assure you. This battery is pretty much the same as the one that came with my D90. Charges, performs and fits like the Nikon brand EN-EL3e battery. If you are stingy about the differences, the Nikon brand battery is a darker shade of grey than it’s Opteka clone. Let me remind you that this difference does not effect the performance or quality of the battery itself.

Having this battery is nice since I’m doing a lot of video work with the D90. I have an external Nikon SB-400 flash unit so i dont have to worry about the camera battery’s juice getting sucked up.

5 Stars GREAT PRODUCT
PURCHASED THIS PRODUCT A FEW MONTHS AGO AND I’M PLEASED TO SAY THAT IT WAS A PLEASANT SURPRISE TO ME. THE BATTERIES LAST MUCH LONGER THAN THE ONES THAT CAME WITH MY D200. I USE THEM WITH DARKROOM PRO TETHERED TO THE COMPUTER WHICH CAUSES THE BATTERIES TO DRAIN FASTER AND LET ME TELL U THEY DO NOT DRAIN AS FAST AS THE OTHERS. I STRONGLY RECOMMEND THESE BATTERIES AND I’M GOING TO PURCHASE 3 MORE ADDITIONAL BATTERIES FOR MY BACKUP CAMERA AND SINCE I USE A BATTERY GRIP I NEED 2 FOR EACH CAMERA AND A BACKUP. I CURRENTLY HAVE 2 OF THESE BATTERIES AND I’M GOING TO PURCHASE 3 MORE.
