i have a couple of batteries that are fine most of the time but sometimes just refuse to charge.
i have tried them on 3 chargers but no joy.
when i can get them charged they run fine.
i have 3 ABC800H chargers, maybe they need to be upgraded or something...?
any ideas?

Try cleaning the contacts on the batteries and the chargers with a pencil eraser or a sharp object.

Hi Morgan,

He is correct, you can try and clean the contacts and see if that works. Clean the contacts on both the batteries and the chargers.

If that does not help, I would suggest that you contact our Customer Support Department at (800)541-1667, give them the serial numbers of the batteries and chargers, and they can give you some more suggestions.

Regards,
Paul Dudeck

Hello Morgan,

Being a battery pack assembler and also a consistent recell specialist in the broadcast industry for the last 17/18 years we sometimes see these issues. If your battery is out of warranty...

We have seen issues with several of the digital type batteries.

Your H50 is built by AB and obviously promoted with an AB charger.

In the last two days our people have talked with customers in the field with many Ni-CD and Ni-MH Digital battery packs that are sitting on shelves because their complimenting smart charger and those batteries are not communicating with each other. Each is sending in several now for rebuild and repair. We have written in this forum about these issues before. Hope I do not make any made this time.

Rough Draft:

Some of the issues are that:
The battery goes to "HOLD". If it goes to "HOLD" it will not charge. We and several of our staff have personally seen instances where a particular problem battery reads "HOLD" but the 2702 with DDM continued to charge the battery. We would not pretend to know exactly why we have seen this happen but suspect it to be a glitch. We have an article on our Hytron 50 recell page about H50 Precautions. Too much for here.

THis can be because the contacts are oxidized and need a simple cleaning. If that fails your issue is internal. It could have been caused by being dropped damaging a circuit board component, a thermal sensor, pinched wire, broken board components caused by the stress and extreme tight placement of the weld tabs against the bottom of the cb which, unlike other boards, has components on the bottom of the cb, or it could be damage from an ameteur rebuilder. We see it all.

You may not be paying attention to your charger LCD read out when the battery has finished charging. The final charge should read a delta cut-off, a TCO, a VCO, or a CCO cut-off. The delta is your first line and the preferred cut-off. TCO and VCO are still OK and the battery is reaching full charge potential.

But if it reads CCO this is a cumalitive math formula. CCO really means that the charger has finished a safe charge on the battery but the battery has not been charged to its full potential. We normally see a CCO to be approoximately 25% less than required for a proper maximum charge.

When testing a clients battery or testing a clients battery with a new insert and we see CCO cut-off we take the battery pack to a PAG or Cadex analyzer and run the test again. The PAG and Cadex units will safely take the battery to full voltage and capacity and the battery will work fine on your cameera. When we do come across a battery that displays "HOLD" or "CCO" on an AB 2702 with DDM and we cannot correct the problem in-house we remove internal componets from that battery that allows an AB charger to recognize the battery. Thus removing any unforseen potential safety issues due to the "HOLD" reading if they were placed back on an AB charger.

When a customer sends us a problem battery that reads HOLD or CCO they either buy a pre-owned shell from us and we install a new insert in that shell or they purchase a PAG or Cadex analyzer from us.

Your AB battery manual and charger manual has all this information about the Delta, TCO, VCO, and CCO.

IF YOUR BATTERY STAYS ON HOLD REMOVE IT AND DO NOT PLACE IT BACK ON ANY AB CHARGER AGAIN. These batteries will continue to charge just great with a PAG or Cadex analyzer. PAG and Cadex analyzers do not require a logic board or thermal sensors to manage their analysis or charge routine. Thermals are a great back up for the battery and their real job is with the battery, not the charger.

See our web site for our article, the negatives of lithium ion.

We repair battery chargers, repair / rebuild battery packs, sell new PAG and Cadex chargers, rebuild Dionics, service and repair Focus Enhancement Firestorm and Firefly units, electronic lamphead ballast, smart washlamps, and have several other electronic services. More information can be found at www.rathboneenergy.com or www.batteries and circuitboards.com

We do final assembly for any company keeping jobs in the Applichias of America. No Chinese cells. No Chinese Labor. We do not receive or pay exorbidient salaries that run companies off shore.

Our HubZone company here is a true small business, not the 6.5 million dollar small business. Our area average income is under the national poverty level. Our area average unemployment is > 10% most of the time. We would like to gain your business and your corporate and individual referrals.

I hope I have been helpful. I was hoping our Chief Technology Specialist Jim Burns would chime in. Where are you Jim? Jim also does NAS upgrades, etc.

Sincerely,

Have you tried to reset the Hytron 50 with a paperclip in the small hole above the lcd panel???

This fixes some issues that I have had.

Hi Morgan. I've had almost all reciepes of AB batteries. I've found that some chargers don't like batteries to be too depleted of charge. If the battery is too low the "Dumb" chargers don't know how to slowly bring the charge backup. I've had this happen with ABC chargers with panasonic labels on them. It's not a smart charger.
I own two Titan 4 port chargers and a 2704 with the DDS module. Both work well with all AB receipes. Paul Dudeck from AB did send a chip to upgrade my 2704 to charge Dionics.
So if you can borrow a smart charger do so. Try that and see what happens.

Good luck.
