Weak LP-e6 battery
« on: June 21, 2013, 07:31:47 PM »
At least I wonder if it is weak.  Battery check on my 5DM3 shows 2, not 3, bars as condition.  Does this mean anything?

Thanks

Just means it's getting up there in cycle count.  It still has quite a bit of life left, so keep shooting!

Thanks. I downloaded the manual onto iPad and read up on.

I should remember engage brain first (or do a google search) before asking a question

I've never noticed a issue with a two star battery, it happens to me after a year or two.  I've never actually had to replace a LP-E6, I've sold my cameras with batteries before any failed, which means some lasted at least 4 years.
 
I've learned to write the date I put them into service on the label just so I know which is new and which is old.  Canon now puts a date on the battery, but I still mark them.

Both my LP-E6's dropped to 2 squares recharge performance instead of 3 after 12-18 months approx. use on my 7D, they've been doing that for the last 18 months or so, have had no battery issues so far, like Neuro says, just means they've had a bit of use and aren't recharging quite as well as they did when new.

I suspect these batteries would benefit from calibration.  Apple has recommended periodic calibration of the LiPo batteries in their laptops (charge to full, drain to empty, recharge to full).  The LC-E4N charger can run a calibration cycle, and the 1D X tells you when one is needed.

Possibly. But ... original Canon LC-E6 charger for LP-E6 does not offer anything other than "regular charging" cycle. It can neither discharge nor calibrate.

I don't know whether third-party chargers with calibration cycle capability are available. Based on a bad experience with a defect third-party battery for Canon (NB-2LH ripoff) I will personally not again experiment with third-party batteries or chargers for Canon cameras.

My 3 LP-E6 batteries are all down to only 1 "health bullet" after 4 years of use in my 7D [somewhat more than 30k klicks] although I mainly used 2 of them in the battery grip and the third one only as spare, rarely used. But so far all 3 work OK.

I have had to recalibrate batteries for my 1D series cameras.  I don't think there is a calibration for the 5D batteries

The LC-E4N and LP-E6 have the same internal chemistry (as do their other batteries).  Canon provides an easy way to calibrate the 1-series battery, but not the others.  I'm just saying the LC-E6 would benefit from calibration, not that Canon provides an easy way to do that.

Good point.  Canon unfortunately removes any key features from it prosumer cameras.

I try as far as possible to completely discharge the LP-E6 in camera (so it will no longer power the camera) before I recharge it, though I'm not sure if this really makes much difference to battery life/ recharge performance.

If anything, that's worse.  Li-ion batteries are better used frequently but lightly. Frequent full discharges will actually reduce overall longevity.

I saw this on a DP Review Forum:  I can't attest to the authenticity... but it does make sense to me.  Original thread:
http://www.dpreview.com/forums/thread/2506860

"I sent a note to Chuck Westfall asking:

"How does one "recalibrate" an LP-E6?"

His response was:

"...The answer to your question is; "You don't."

The section of the article you referenced is in error on this point, and it will be changed soon. Our apologies for any confusion the article may have caused.

Meanwhile, please refer to pages 28 and 192 in the EOS 5D Mark II instruction booklet for information on using the Battery Info screen properly. Bottom line, if the Recharge Performance indicator turns red, that battery pack should be discarded...""

This morning one of my LP-E6's dropped to the last 'red' indicator. I've been shooting with it all day - 242 photo's and I'm at 76% charge. I wonder what's the benefit of this feature other than making photographers unduly worried and tempted to replace batteries that are still in good working order. It definitely is a drawback if you want to sell used kit...
