Help to find NIMH charger

Hello Guys,

we have problem with NIMH batterys. In our product we use pack with 6 units in series.
The packs are emersed in resin because standards. Therefore we have problem with gas generated and some packs increase your volume.
We bought a smart charger that have many functions and with it verified that batterys need cycle to active your chemical.
This is the point, I need equipament to charge and discharge battery some times, so I can assembly the packet, but the equipament have to many channels because I have a medium volume of production.

Any body know any?

There are storebought 'smart' chargers for batteries. Do your batteries have tabs attached? Then they may not fit easily into the charger.

This probably requires a custom-built charger. You'll want to set a certain number of cycles, charge rate, discharge rate, etc.

Are you testing all your cells, in order to find ones that perform best ('pushed' cells)? Then your charger needs to be heavier duty, so it delivers faster charge/discharge rates.

Tnx Brad, for your answer.

I forgot talk to say a important information. We use AAA batteries. So is easy fit it in charger.
I Have a smart charger (SKYRS NC2500) that make cycle. But it is expensive and only work with 4 batteries at time.

When I test new batteries I realized that it are diferent capacity. Using NC2500 with 4 news batteries, one of them charge in 20 minutes (my batteries are SONY Cycle Energy AAA, sold pre-charged) and other delayed 40 min to finish charge. After it, we use discharge function and measure capacity of group. One of the had 560 mA and other 770mA.
We use charge function again and we note a equalization. The bigger capacity was 811 and smaller was 789 and only 2 minutes of difference between them.

So we want cycle all AAA before do packet, to Avoid overchargin any cell during charge in series.

Yes, good idea to test them. I believe I read that it requires a few cycles for a rechargeable battery to reach its maximum performance.
