Upgrade battery cells

I'm thinking about upgrading the cells in my dead ProFormers, and I cam across some 5000 mAh NiMH cells online.

 

My question is: Does anyone know if it's alright to pop these new cells in as-is? Would there be any possibility that the charger won't recognize their chemistry, etc?

 

I don't mind destroying my already dead ProFormers, but I definitely don't want to blow up any cameras, chargers, or myself!

 

Thanks!

Thank You for the referrals/endorsement !!

 

The NiMh cells can be installed in the ProFormer, just be aware that the cells are slightly larger so the case will have to be modified.

 

I have 2 Proformers with fresh cells (NiMh-55 watts) available ready to go if you need them in a hurry, plus I can provide another 6 with a 2 day lead time, no trade in required.

I can also Re-Cell your dead packs (3-5 day turn around, plus shipping time).

 

I also do all of the Anton Bauer Battery line; pack/VCLX/Dionic repairs/Re-Cell and any other manufacturer (IDX, RED, Sony, Frezzi, Tiffen, Blue Shape, BeBob, Swit, Switronix/Pro-X, Varizoom, Imports

 

I am also an authorized repair station/dealer for Blue Shape Battery products.

The Ni-Cd charger will charge the Ni-MH batteries but at a price.


Heat KILLS batteries. If your charger does not turn off at a certain voltage point (Ni-MH charger) it will keep charging until a certain time has passed (Ni-Cd charger). This excess energy translates to HEAT in your battery and diminishes its life and then you have to get it re-celled again sooner than you would have if you had just put Ni-Cd back into it.


You have to weigh out the cost of either:

1. Having lots more watt hours to work with right now with a Ni-MH re-cell and possibly having to re-cell early,

2. Or putting Ni-Cd chemistry back into it with less watt hour to work with and having probably longer life.


Make sure and charge the batteries up fully before you build your battery pack. Many batteries have been sitting on the shelf for a while and have naturally degraded over time. Charging them up first before building the pack will assure that they are all close to being the same voltage as each other and you will have a longer life span from them.

I use real Anton/Bauer battery chargers, so I assume that I wouldn't have to worry about this.

I have successfully re-celled my Proformer! This was my first attempt, and minus one ground incident that caused some sparks, it went on without a hitch! I replaced the 30 Wh NiMH cells with 5,000 mAh NiCad cells, bringing the Proformers to 72 Wh. It took me two hours, and I had to modify the case as John mentioned. For a first try, I think I did well.

 

Here's are some pictures of the process: https://plus.google.com/photos/105188795616289789466/albums/5980828415844421121?authkey=CK33meHWuK-0IQ
