EOS80DLCDBCKBattery info

One of the screens found in the menus of the later EOS models is ‘Battery info’. This first appeared on one of the professional models in 2007 and has been included in all of the higher end models since then, as well as others from across the EOS range. So just what can this menu option tell us about the battery performance?

Professionals are hard on their Canon gear, and no other single piece of equipment shows the wear and tear more than the humble camera battery. That's why, with the introduction of the EOS-1D Mark III in 2007, Canon added a new menu item. Called 'Battery info', you can now get information on just how much life your battery has left, both in the short term and long term.

The new menu option was then added to the EOS 5D Mark II with the introduction of the LP-E6 battery. Canon has now launched the higher capacity LP-E6N battery with a slighter increased mAh rating.

The ‘Battery info’ menu option has filtered down to enthusiast models and can now also be found on the EOS 750D and 760D cameras, introduced in February 2015. These were the first of the entry-level models to offer details of battery performance. They use the new LP-E17 battery which includes same technology as the LP-E6N.

‘Battery info’ tells you

Batteryinfoscreencanoneos

When you select ‘Battery info’ from the yellow Setup 3 tab and press the ‘Set’ button it takes you to the screen which shows you three key items:

Remaining capacity
The first item is the remaining capacity of the installed battery. Special circuits and a memory chip in the battery communicate the precise percentage of charge remaining in the battery, in 1% increments.

Shutter count
The second item on most screens is the ‘Shutter count’. This shows how many times the shutter has been fired for still images (movies are not counted) on this particular battery on this charge. When the battery is recharged the number is reset, so it cannot show you the total number of shots that the battery handled. The ‘Shutter count’ is useful as it shows you how many shots you are getting from a single charge of the battery. If this number starts dropping it is a sure sign that the battery condition is starting to deteriorate. This feature is not included on the EOS 750D, 760D and 800D.

Recharge performance
The final and possibly most important information is the recharge performance. This shows the battery’s condition and its ability to supply power.

Photographers often think that you can buy a battery and it will last forever. This is not the case. Batteries have a finite number of times that they can go through a recharge and discharge cycle. There is no exact figure as lots of things influence the expected life of a battery, but it is generally agreed that they last for between 500 and 1000 recharge/discharge cycles.

One of the key factors that can affect battery life is constant topping up. Shooting a few images and then charging the battery will shorten its life far quicker than using the battery until it is almost flat and then recharging it.

Battery age

Many batteries in current use could be quite old. The LP-E6 battery first appeared on the EOS 5D Mark II, which came out in September 2008. If you have this model, or a model out at around the same time, the batteries you are using could easily be over seven years old and in that time they might have been recharged hundreds of times.

Batteries can also deteriorate if left flat or stored for a long time without use. This means that even if you have not used the camera much the battery condition may still have suffered.

Battery condition becomes especially important if you are going to a country where mains power availability is limited. You need batteries in tip-top condition so that they will last as long as possible.



Performance guide

Here's what the coloured bars mean on the Recharge performance item.

Battery is providing full performance each time it’s charged.
 

Battery still producing good power each time charged, but not to the level of a new battery.

Battery is nearing the end of its useful life; a full recharge will not deliver the same performance as a new battery.

Battery has reached the end of its useful life, and should be discarded and replaced with a new battery. Recharging or re-conditioning will not enhance its performance.
