Washed 2 of my cameras batteries, any chance will these still be good?

5 years 2 months ago #628569 by Tim Wiener
I'm so in disbelief that I did this.  I have never forgotten about my camera batteries and washed them before.  EVER.  I've heard about people washing memory cards and them being OK.  But batteries?  

These batteries are for my D810. 

I have them sitting out right now.  I'm nervous about putting on charger or in my camera. 

I've seen some helpful post here, so putting this out there for some sound advice.  

Thank you!

Tim

I would let them sit for a couple days in some rice.  Then stick voltage meter on them.  If that looks good, toss on the charger.  Should be OK.

OK, I'll try that.  Thank you. 

I'm still in shock that I did this!  :pinch:

I assume you mean the "original" pack?

First, use the voltmeter. If you get a reading good but
to be on the safe side, have them sit a day in circulating
warm air.

If not, I would let them sit on a heating body for a couple
of days in a warm (no more than 30° C is necessary) and
circulating air checking the voltage say every day. if after
three days you still have no reading, try to charge it using
the kick starting technique; the pack may be dry and emp-
ty. If you can't kick start them… you'll need a new one.

Huh?  I leave my batteries charging over night all the time.

Quick and complete drying is the key to success.  Complete is slightly more important than quick.

There are photographs everywhere. It is the call of photographers to see and capture those images.

That is a great risk you take every time… even with the
best batteries. Batteries may heat up, and burst or set
fire. One never knows when something is going wrong
in a tight shut cell! 

I charge mine after a shoot if necessary and the charger
is beside the working station; they have time to recharge
and go back in the camera, along with the cards, so I am
ready for the next day.

Now don't most battery chargers move to a trickle charge once they have been fully charged?  Are you using a camera manufacture battery charger or 3rd party?

The safety issues are what I experienced when working
in a charging technology lab as consultant.

I agree, many safety disposition were easy to implement
in the past 20 years but ONE was not implemented and
that is temperature control.

The trickle mode is, roughly, started when the battery has
reached about 80+% and is a good safety measure as well
as a maintenance mode… but don't forget that this is an en-
closed cell though with safety "valves".

When it come to the safety of my home, my family and my
studio, I will afford — in my case built because I can — only
prime technical equipment that will charge with temperatu-
re monitoring. Sometimes, I also go to bed forgetting about
them.

I've done this.  Batteries were completely fine after I let them try out for a week.  Might have been fine sooner, however I just let them out while I was traveling.

I washed my memory card once and my wireless trigger.  Not at the same time.  Memory card survived and the trigger wasn't so lucky!

Hey Tim, what's the update on this?  Did you try them out after you let them dry out?
