Hi guys,

I hope that some one can help, it is off topic but relates to chargers that I use for my T-Rex.

I need to charge 10 x Sanyo AA batteries for my Meade Telescope and I am having one hell of a time using my Schulze ISL6-330DE and Swallow Digital chargers to get the job done.

I have tried to charge the cells in series in those cheap plastic battery boxes that you can buy from electronics places but they're not charging as they should. For a start, the schulze on Auto D/C charges at only 0.3 amps. Also, should it not automatically detect the number of cells, seems that it is always off, like 6 or 7 it sometimes reads. Would these charges have trouble detecing necessary voltages because of the way the box is wired? What is the best way to charge these individual AA's? Someone said that I need to get tin and solder them in series, but what a pain!!!
As for the swallow charger, it worked ok but did not stop after putting back 2500, they began to get darn hot!!!

I realise that this is confusing and off topic but I would really appreciate info from you experienced AA chargers out there

Regards.

Logan.

Ok, problem solved, hope this helps someone

Instead of using the $300.00 Schulze charger that shuts off automatically after 4+ hours I had success with the Swallow Digital Charger as this has no timer cutoff. I charged the 10 x Nimh batteries in a cheap plastic battery box with + and - cables on a charge rate of 0.25 amps for around 14 hours. The charger stops charging these packs when it has put back in around 2575mAh. Success.

Not so complicated after all

Slow trickle charge is the only way I have found to make it work. Run 3 x Discharge/Charge cycles to break in the cells. It takes time but this is the sure fire method.

Cheers.
