H System Battery reset

Ok, will give the contacts some booze...

forget about Bourbon. It's too sticky ahahaha
I used pure ethanol at 99.9%. Hard to find and to buy but works well.

Redid the reset 2 more times, and rubbed contacts with methelated spirit for good measure. Battery shows 100%, went for shoot...at end of shoot...165 frames, battery shows 65%. the battery lives to shoot another day.

Thanks for tips.

nice !!

This is a great thread, very useful information for a location guy like me running 7 batteries for my camera.
Thanks to all!

I just charged two batteries. The camera indicated that one was at a 100% and the other at 5%. Does this mean that the second battery is spent or just that a reset for this particular battery is required? Thank you.

I would charge both batteries again, for at least 12hrs.
After that, a reset for both.

I also had some trouble resetting a battery on my H3DII-39 but after resetting different battery successfully, I was able to reset the problematic battery and got the 100% back from it.  Right after I reset them, I re-charge them overnight just to be sure of getting them fully charged.

Performing this with no lens and no viewfinder is the trick!!!

Thank you.

damn...did i kill my H2?

just got a new (to me) H2 with battery.  i have two other H batteries from my previous H3 (H3 now gone).  charged one battery for four hours, checked out the H2, worked great.  charged two batteries 12 hrs.

then I read this reset thread, thought i should get my batteries up to snuff:

flash/menu, insert battery, got the fast beeping, did all three

now H2 will not turn on with any of them, even after 4 hrs more charge (slow blinking light on charger)


oops...got it to work, must be a senstitive on switch as persistent push-hold did the trick

I doubt very much you have killed your batteries.. Are you pressing and holding the power button?

I did the reset trick as described by Nick, and then recharged my 4 batteries, but then I thought I'd check them by doing the reset thing again. A couple of them gave off the fast beeps again, so I recharged them again.

Is this to be expected - that we may have to reset them more than once? Or is something else wrong?

The H batteries are a consumable item they have a limited life span like all rechargeable batteries made by every other manufacturer on the planet.

Just because you can reset the battery to show a 100% charge does not mean that it is holding a 100% charge of a new battery.

Think of your cell phone, it has a rechargeable battery but after a few years of service you will have to replace the battery because it will no longer hold a charge.

Hi - Make sure you remove the viewfinder when doing the reset

[cerett]

One more thing - I believe the beeping will occur whenever you do a reset. It has nothing to do with the ability of the battery to accept a charge or the current status of the battery. BTW, anybody know when the new batteries will be available?

In my experience the batteries lasted very well and rarely fell below 80% nominal capacity when checked with a dedicated battery analyser. Keep the contacts clean, perform a reset from time to time, don't drop them, there is not much else to say.
