The situation is known to every photographer: the camera battery is dead, there is nothing to charge it with, but you need to shoot. Alternatively, there is charging, but the nearest outlet is very far away. Of course 2–3 spare batteries will help. But what to do when the spare batteries run out? A battery with a built-in charging connector will come to your aid. Cheap, capacious and convenient — Canon LP-E6 in my case. Let me tell you about him.
The product is simple, so the review will be short.
Packaging and appearance
A cheap cardboard box, inside of which lies a plastic box with the battery itself and a charging cable
Unlike the mass of outright clones, this battery does not try to impersonate the original. It follows the general layout of the Canon LP-E6 battery exactly because otherwise it would not fit in the battery compartment. Otherwise, everything is its own — red color, rough plastic and — most importantly — a built-in charging connector!
The Batmax office that produces it also offers a lot of other batteries, and every little thing for cameras too.
Please note that the original has a 13 watt * hour capacity, while the Batmax 20.7
Micro-USB, of course, is better than nothing, but I would still like it to be more convenient in general (and even more so when charging “in the fields” and even more so) Type‑C. In the new ones, as I understand it, already type‑C, nevertheless.
More recent batteries for cameras with built-in charging connectors from Batmax already boast 3‑segment LED indicators and a button that turns them on. This is much more convenient, as you somehow can evaluate how much the battery is charged, and the charge level of stored batteries without inserting them into the camera.
In my case, the indication is the simplest red-green eye.
Photo battery charging test
The charging current is small, only 0.5A, so you should not rely on fast charging.
I don’t shoot much, and I have 2 other spare batteries, so I’ve only charged the Batmax battery about ten times in a year. So, technically, the battery is not new, but it’s also impossible to talk about some kind of intensive use that eats up battery capacity. If the capacity during this time sank, then I am sure that it is quite insignificant.
So, let me remind you, they promise a very good capacity — 20.8 watt * hour at 13 watt * hour for a native battery.
For those who are not in the know, here is a simple explanation of how to correctly calculate the battery capacity and why it is wrong to calculate the capacity in mah. In the latter case, the numbers will jump strongly depending on the voltage. And if the last is unknown, then all these mah at all are meaningless, because the same capacity of 3.7v and 12v batteries expressed in mah will differ by 3 times … But watt * hours are always the same, despite the battery voltage.
So, a year later, 11 watt * hours are poured into the battery. Of course, the real capacity is less, because there are still charging losses. And in order to accurately find out the capacity of the battery for the camera, you would have to disassemble this battery and separately measure the capacity of each of the two li-ion cells included in it. Since I use the battery and will use it, I have no interest in this. Such approximate figures will suffice. Most importantly, the capacity suits me quite well.
The battery with built-in charger for the camera is a real salvation. All you need now is a power bank or a solar panel, there is no need to take a separate charger with you. Now you can charge the battery for the camera right in the car, on the go, in the country — anywhere. And the space occupied by a separate charger can be useful for something else. For example, two additional batteries will definitely fit.
The only thing worth noting is that some external chargers for photo batteries will allow you to charge faster, with much higher currents. And, technically, they can also be used on the go or “in the fields” since they have a type‑c input.
Whatever it is, I’m satisfied. I don’t want to return to external chargers after buying this battery with built-in charging, although I have 3 of these and 2 of them are modern and fast. It is much easier to insert directly into a block with USB outputs (if you need a powerful one, here review 100w GaN charging Ugreen)
By the way, if you often shoot “in the fields” and edit the footage in the same place, then for sure you will find it useful to review the most powerful power bank with 100w and 220v outputs, which will also pull a laptop.
