This morning, I put my LP-E6 battery for my Canon EOS 7D camera on to charge in the standard LC-E6E charger, but it did not charge at all.

The charger has a single LED which shows the charging state of the battery. While charging, the LED is orange – it flashes once and pauses when the battery is less than 50% charged, twice and a pause when the battery is less than 75% charged and three flashes and a pause when the charge is less than 100%. Once the battery is fully charged, the LED turns green and lights continuously.

*   *   *   *   *  < 50%
**  **  **  ** ** < 75%
*** *** *** *** *** <100%
******************** = Problem!

When I connected the battery, it flashed orange rapidly with no pause.

To fix the problem, I unplugged the charger, I cleaned all four contacts using a dry duster. There are two copper ‘blades’ and two silver ‘bent wire’ contacts. The charger seems to gather lots of dust. I also cleaned the contacts on the battery taking great care not to touch them with anything conductive. The exposed contacts can be rubbed gently with a cloth, but the two slots which connect to the ‘blades’ on the charger are harder to clean. I folded a clean piece of paper in half and gently pushed it into the slots – there was a small amount of fluff which came out of the slots.

When I put the battery on to charge again, it was showing 50% charged and after a few minutes showed 75%.

I hope this will save you spending £75 on a new battery, or £50 or a new charger!

  1. doesn’t work for me, do you think there are other ways to fix this? i just bought this today never used it ugh

  2. You could try a different charger, and a different battery to work out whether its the battery or charger at fault.

  3. I just repaired an LP-E6 battery (third party) that exhibited the same symptom (constant flashing led). First I cleaned the contacts – no change.
    Then I decided (just out of curiosity) to short the contacts of the hard to get to pair (I had to slide a thin metal ruler, and a metal nail file in the slots). Now it is charging again!
    Maybe I was just lucky.

  4. I have the same problem with my 2 Canon LP-E6 battery’s. So I thought problem is in the charger. but I let the battery discharge fully by connecting a PC fan and let it discharge completely(short circuiting a battery can led to a explosion) . it took me one night. then the battery charged fine but newer accomplished the 100%. and my 7D say the condition of the battery is two stars (I used this battery’s more than a year, back then always the condition of the battery is three stars)

  5. Same problem here, with both lpe6 batteries I have I always have to watch the charger to make sure it does not all of a sudden start flashing continuously, mostly when it does I pull it out, put it back in and it works again, sometimes it takes a couple of tries but now there is one battery that I often plug and the charger doesn’t react at all… I tried cleaning and it didn’t really change anything, am afraid to try the shortcut method though…

  6. I just experienced this problem with a relatively new battery and charger.

    After reading this blog, I took a close look at the 2 spring loaded contacts in the charger and noticed that one wasn’t springing up completely. I used a narrow blade to wiggle the contact (with the charger off!) and now it has sprung out and the battery is charging properly

    Hope this helps someone.

  7. I took My shirt and began to wipe the metal contacts on the actual charger and found the battery started to charge after that. So again I took my shirt and wiped both the battery and the charger metal contacts and it worked hope this helps .

  8. I just purchased three new LP-E6 batteries (Canon) each one won’t charge, constant flashing amber lights, I am not happy with Canon, what gives?? I am using the correct charger supplied by Canon. So I unplugged it, removed the battery, plugged it back in and rammed the darn battery back in, now it works! I am dumbfounded!! Also dumb I could have broken the charger although I am not that strong really. The battery light is showing at one flash. Awesome!! Hope the rest will respond the same way.

  9. Just bought a 60d and had same problem.

    Wiped leads cleaned with a clean towel and paper towel for the slots in the charger. I also pulled the charger prongs out a bit with a pointed knife and now the battery is charging fine.

    Thank you for all the advice above.

  10. facing the same problem , my canon 60D wont turn , sometimes it work ! battery showing full charged after few pictures its become 0% ! then a shutdown , when i charge it again , it doesn’t work ! after a time it work , WTF is that !!!

  11. This seems to have worked for me.

  12. I just bought another Canon LP-E6 battery for my Canon 70D camera. When I charged this new battery for 203 hours with LC-E6 charger (as I did for the orignial one caming with the camera), I got a big trouble: My charger and the battery got very hot with orange light flashing quickly; it showed about 50% charged. I took it out and followed Canon’s Official Instructions to fix problems, but the same problem remained unsolved. Then let them cool, and re-charged it witha a fan aiming at the charger place was running. This time the charger did NOT become hot, after about one hour, the green light is ON, and I checked it and it showed 100% charged. This evidence indicates that the trouble was due to increased temperature in the charger. I hope this problem can be solved. Keep the finger crossed for next battery charging.

  13. Hi everyone,

    I’ve fixed the problem with my electrician co-worker teacher’s help.

    If any of others suggestions and solutions might not seems to work with you guys try these:

    THE PROBLEM:
    The battery is dried out, meaning the battery is dead.

    THE SOLUTION:
    You need to SHOCK the battery like a dying man being shocked by “Defibrillator” in the hospital.

    EQUIPMENT NEEDED:
    -Regulated DC Power Supply
    -Continuity tester cables
    -Alligator clips

    IF you don’t have these resources just go to an electronics shop and do the same procedures OR just buy a new battery. XD

    PROCEDURE:
    Step 1: Set the Regulator to at least twice the batteries needed voltage(Depend on you)
    Step 2: If you see that the battery is alive lowers the voltages to the battery’s need for about 20-30 minutes.
    Step 3: Try the battery in the charger if the blinking stops, if not repeat step 2(But I think 20-30 minutes is enough)

    And there you go. You battery is alive and ready for work!

  14. it works for me, I cleaned the contacts both battery and charger then press the battery harder to the charger, it start to charge in normal mode.
