Railfan Technology > Dead Nikon D80 battery help

I sent my Nikon D7100 in for repair and adjustment yesterday and I got out my old D80. I went to charge the batteries and 1 of them took a charge very well and the other was very dead. When I put it in the charger the light would flash 3 times then go out. the charger would not charge it. I tried to charge it in my Maha charger and I let it go for a few days and all it did was put 5 milli amps into it. I have read a bit about Li-po batteries and it seems that they might not be able to be rescued.

Does anybody know if you can rescue a dead Li-po that has been in storage for about 3+ years?. I will not be buying another battery as 1 works and the D7100 should be back in a little bit hopefully less than a month.

You could try searching YouTube for a way to charge it. There seems to always be someone with a fix for these problems.

I have also experienced a suddenly-dead EN-EL3e. Curious to hear if anyone has a solution.

... Or just keep your batteries charged. The
D80 has to be about 10 years ago.

John.

Battery packs can be rebuilt, and the result is like new. Retail stores like Batteries Plus Bulbs can do it. I don't know whether it saves money over buying a new pack, but it is worth exploring.

I just traded in my D90 a couple months ago, but I already gave away my spare battery. If I still had it, I would have offered to send it to you. Having two batteries is always better, even if it wont get much use.

Last week, the six-year-old Delco Group 90 in my Chevy expired almost exactly at six years after installation. It was the third battery in the car since new.

That Delco had replaced a Delco that failed in about seven months after installation.

The seven-months-to-failure Delco had replaced a five-year-old OEM Delco that had experienced no problems but was replaced proactively to avoid a late-term failure at an inconvenient time.

Go figure.

Batteries, you can't live with them and you can't live without them.

Yes, but still functional and suitable as a "beater" camera to keep in the car. Battery-life indicator still showed "new" condition, and I have a pool of them that I rotate regularly between D80, D200 and D300S.

The Utube solution for power tool lithium batteries is to take a battery which works and run jumper wires from + to + and - to - between the working battery and non functioning battery. You only need to leave the jumper connections for 30-45 SECONDS.

This operation establishes a reference voltage on the weak battery so the charger will recognize it as a functioning battery and try to charge it.

I have had 50% success with this method on a cordless power drill. You do this at your own risk and I never let these batteries out of my sight during the jumper or charge operations.

You can find replacement batteries on Amazon for $50 - 70 for a brand name battery or a fraction of that for a 'knock off' brand battery. I've had reasonably good results using the off brand battery in my Canon bodies...
