DSTE® LP-E4 Replacement Li-ion Battery for Canon EOS-1D C EOS-1D Mark III IV EOS-1Ds Mark III IV Digital Camera

I didn't have high hopes for an aftermarket battery. The price discrepancy between Canon and this one were a huge put off. I gave this a shot and found that it works perfectly. It fits as it should and hasn't given me any trouble so far. I say it's a win.

This is one of those you get what you pay for type products.First off, if you expecting an OEM battery you can spend 6x what this one costs to get those standards. I call these my back up batteries that I use first while on a shoot or out in the field.I have 2 Canon OEM batteries which can be recharged for years, have no problem communicating, and are my reliable sources of power. Along with those 2 OEM Batteries I have 4 of these inexpensive batteries that do the job when my shooting is a little more flexible. They probably hold about 80% of the charge an OEM battery has and after a 12-18 months I expect my camera may stops communicating all together or it will no longer hold a charge. That's the nature of the game.However, if you go into this purchase knowing that then you shouldn't be surprised if one dies on you. When you're out in the field and you need power I recommend using your OEM battery last and using these batteries first. They will more than likely give you all the charge you need for your shoot however you have the added insurance of an OEM workhorse sitting in your bag ready to go if you run out of juice. With one exception, don't rely on these batteries during a "no second chance shoot". Meaning I wouldn't have these batteries in my camera during the wedding ceremony or the start of a race, however if you are doing staged shots or won't be affected when the battery runs out of juice and you have to switch batteries then you will be fine.Again for the price they are offering these at you can have 5-6x the power in your bag, however they do not replace the reliability of an OEM battery, so don't assume they do.

Works great holds good charge at a very reasonable price

Works perfectly with my EOS 1Ds Mark III. Charged right up in the factory charger and powered up the camera with no problem. I like the added capacity over the stock battery.

It arrived half charged. I haven’t needed to use it yet but now I’m charging it to see if it’ll hold a full charge. Will update review when I know for sure.

Like the title states- this is a great battery. Cant beat it for the cost. Works well with the Canon 1D Mk4 and has no software issues with the battery meter as other knock offs might. Camera loves it- I love it.

Seems to work fine, figment isn’t 100% and I also wouldn’t trust this battery to seal out moisture. But it works it reports back how much battery is left I. The LCD screen. Since canon makes newer batteries that are compatible they no longer sell OEM versions of this battery so it’s a good as it gets. To go canon you gotta buy a newer charger that is $300 and then the batts are ~$160 so this solution is less than 1/10 the price

Outstanding service and the battery is working fine
