The Synergy advantages are even more glaring when compared to typical NiMH batteries: not only are they ready for use right out of the packet, but they generally last longer than most NiMH batteries (continuous and frequent recharging can destroy other NiMH models) and save both time and money (traditional NiMH charging is slow when you're in a hurry, while rapid chargers are expensive). All told, you can recharge these batteries up to 500 times without experiencing a memory effect; just charge the amount you need and you're set." Most are claiming a typical NiMH chemistry. One I had read claiming Li-Poly (and can't find that thread now). It could be I read that page too fast and confused it for a Li-Poly chemistry. Which had me wondering because Lithium chemistry will define 3.7v. Though I couldn't figure out how they got 1.25v base voltage from HiMH chemistry either. Then there's also the "Mignon" (not Synergy) brand name from Hahnel that also claims NiMH chemistry. Maybe they're just a new NiMH configuration and not Li-Poly. In either case, they seem to be an improvement over the more recently popular "Eneloop", "Hybrid", and other "pre-charged" NiMHs out there. The rated 1.25v strongly suggests a different chemistry. So I was wondering if anyone's been using them and if they perform up to their claims. I do a lot of near-arctic-temperature photography at times (down to -44F) and any improvement in cold weather performance, as well as reliable fast-recharge times, intrigues me.

We all know you are incapable of judging photographs. http://www.arumes.com/temp/nimh.jpg -- Regards, Robert http://www.arumes.com

Oh, and Mignon is not a brand name. It's just another name for "AA battery". -- Regards, Robert http://www.arumes.com

There appear to be two "Synergy" battery product lines, one produced by Hahnel in Germany and the other by Synergy Digital in Brooklyn, NY. The Hahnel product appears to be an Eneloop clone while Synergy appears to be importing Chinese-clone OEM-replacement camera batteries.

The Sanyo Eneloop low-discharge NiMH battery technology is being licenced more widely nowadays. Initially such cells were sold by name-brand battery manufacturers such as Rayovac's "Hybrio" or Panasonic's "Infinium". Nowadays I'm seeing more and more online suppliers of tech gear such as the British-based Maplin stores offering similar low-discharge cells with their own branding (in Maplin's case they're called Camelion). I'm guessing that the Synergy cells mentioned are the same as everybody else's, run off a single production line and only labelled at the end to differentiate them from the other people selling such batteries. -- To reply, my gmail address is nojay1 Robert Sneddon |
