Canon EOS Rebel t3i Battery

The LP-E8 is the official Canon EOS Rebel t3i Battery. It works with the Canon T2i, T3i, T4i, or T5i cameras. Canon switched to an LP-E17 for the subsequent "t" cameras, the t6i, t7i, and t8i

Whether you just found a t3i in your closet, or you're a beginning photographer on a budget, the Canon Rebel t3i can be used to take great photos and improve your photography.

The LP-E8 is a lithium-ion battery and has no memory effect, so partial discharges and charges do not affect it's memory capacity. That means you can charge after each photo shoot to insure it's got a full charge for the next time you want to take photos or video with your Rebel t3i.

LP-E8 Performance

A fully charged, new LP-E8 battery will last for between 400 and 500 photos, depending on your shooting tendencies, and whether you use live view to compose your shots. Using live view can reduce the photo capacity down as low as 200 shots .Shooting video requires a higher use of battery power and will shorten the life of the battery down to 90 minutes.

LP-E8 Specifications

LP-E8

Here are the specifications for the Canon Rebel t3i battery.

1. The LP-E8 is rated at 7.2 volts.
2. Storage capacity of 1120mAh (milli-amp-hours).
3. It produces 8.1 Wh (Watt-hours)
4. It weighs .8 ounce.
5. Dimensions are 2 inch by 1.45 inch by .58 inch

New OEM (OEM is the abbreviation for Original Equipment Manufacturer) Canon battery and any new replacement batteries will last a long time, particularly with shooting regular photos while using the optical viewfinder.

Canon EOS Rebel t3i Battery Alternatives

You have three options other than the LP-E8 batteries to power your Canon T3i camera.

1. You can use alternative batteries-that is batteries for your Rebel t3i that are not made by Canon. There just as good as the Canon batteries in terms of holding a charge. They're a lot cheaper in terms of price.
2. You can attach a battery grip. That will double your capacity to shoot and give you access to camera controls while you're shooting. Again you can buy a OEM battery grip or a third party knockoff.
3. Finally, you can employ an AC power cord connected directly to the AC current in your home, the ACK-E8. That means you'll have a wire connected to your camera, but also means you never have to worry about battery failure or battery charging.

Alternative Batteries

The alternatives to the Canon batteries are much more affordable. At the time of this post update, you can buy a pair of these Powerextra batteries for less than $14.

You can also purchase them with higher capacities than the standard 1120 mAh so they will last much longer than the originals.

I won't recommend a specific alternative right now, because there are so many good ones for the very popular T3i camera.  I buy all of my spare batteries from Amazon because of their liberal return policy, good prices, and their un-matched customer service reputation. 

Canon T3i Battery Grip

The Canon T3i battery grips and their alternatives can be loaded with two batteries to double your shooting capacity.

They also give you comfortable access to vertical shooting camera settings and will give you a better balanced feel when shooting with a long lens attached to your T3i.

Here is more about the BG-E813 Battery Grip for the Canon T3i.

Alternative Power

The ACK-E8 is a power adapter the plugs directly from your AC electric outlet to your camera. These are great for studio work and inside photography where you have electrical outlets available.

Once again, going with a third party is the smart thing to do here.  You can save quite a bit of money by going with a non-Canon power source.  

Just make sure the accessory specifications match the camera's power needs, buy from a reputable seller, and read the reviews of other buyers first.

Canon Rebel t3i Battery Accessories

The most important accessory for the LP-E8 or equivalent battery is a working charger. Canon's version is the LC-E8E. Lithium batteries are so easy to use because of their ability to be charged at any stage.

It was not too many years ago when re-chargeable batteries were ni-cds(nickel cadmium) and had memory issues. If not fully discharge and then fully re-charged, they would "remember" to stop charging before they were at full capacity, thus diminishing their shooting capacity.
