Ricoh GR Digital II battery life with AAA NiMH. Hmm.

[Dante_Stella]

I ran a quick test of the GR Digital II with 2 x Energizer 800Mah NiMH AAAs. Much to my surprise (or maybe not), the camera got through over 200 pictures (non-flash). Test condition was with SanDisk Ultra II 2gb, indoors, with about a 10 second interval between shots.

My test with alkalines was pretty true to the 35-40 frame figures I have seen.

My surmise is that MiMH cells are much flatter across their discharge cycle, although they (nominally) start at 1.2V - and alkalines start high but rapidly dip below the voltage that the camera sees as "ok." I had a similar experience with one of the early Konica "flat" (folded optic zoom) p/s cameras that took AAs.

When I get a chance, I will measure the start and end voltages for each type of cell.

The NiMH thing (assuming it is not a fluke) is big - since you can charge 4 AAAs in 15-30 min (assuming you are not worried about shortening the battery's life cycle) - and it takes a couple of hours to fully charge a DB-60 battery. Good emergency power. This also says good things about the survivability of the camera after DB-60s are discontinued.

Has anyone dropped in the Energizer E2 Lithium AAAs? How did that work out?

That's impressive. I just bought the GX100 and will be keeping some NIMH's around just in case.

for a 2 AA camera. All the P&S's I've owned use AAs or proprietary batteries.

I've used dozens of name brand and generic NiMH's and like the Sanyo Enerloops quite a bit, though for toys or applications where I may not recover the batteries, I like cheap alkalines, usually < USD $0.20 each in bulk.

I bought a pack of AAA lithiums for my GRD over Thansgiving when I realized I'd left my spare battery and charger at home. I haven't been overly impressed with the Ricoh battery, and am very unimpressed with the generic spare, so I needed the insurance. Oddly enough, I went that whole weekend on the one battery.

So, long store short, I'll let you know ;) I keep the lithium AAA's with me now, so I'll need to use them eventually.

I've had great luck with Maha chargers and the Powerex brand of rechargeables. So much so its all I use now when I need a regular sized battery. Outlasts everything else NiMH. I've only seen them here: http://thomas-distributing.com/index.htm
