Default rechargeable Lithium Ion

Double AA Batteries. Do they exist?? my Fuji takes Double AA's and I use Rayovac rechargeables right now, they work, but I like L'ion for no memory.

Don't know of Li Ion AA cells, but if your camera can use CRV-3, there are rechargeable versions of that. Check first, though for compatibility, as the cell voltage may be a little too high.

G'day mate

I use lots of rechargable AA batteries in cameras, torches, tranny radio, etc. All mine are NiMh from a variety of makers

Common are radio shack, best without doubt are Sanyo Eneloops, worst [consistently bad and very not recommended] are EverReady Energisers

My batteries are of varying ages and capacities - 2000 to 2500mAh range
ps- I recently had to dispose of my oldest set of AA rechargables - 2 of the 4 started playing up. Sad as they have been doing great service since 1986: they were RadioShack brand

I refuse to use Energizer batteries, they're garbage.. I had a set of their recharge-ables only last me 4 months.

My Rayovacs have last about 15 months before they have to be replaced.

No the Fuji HS20 wont take a batterpack at all. it has to be AA's as the slots are 4 individual, and designed only for the AA's.

I'll get a photo of my camera battery compartment

LiION cells are 3.7V ... happy using them instead of NiMH-AAs :-) (1.2V)

I have had good results with the Energizer hybrid rechargeable cells, marked 'accu'.
Very good charge retention up to about six months. The Duracell pre-charged (also a hybrid) have given me similar service.
I haven't run across the Li-ion AA size cells here in the U.S., probably because of the potential problems with lawsuits by the litigation happy uninformed.

Please clarify as you say you are happy to use a cell with a voltage THREE times higher!? That would mean that my Pentax DSLR designed to run on four 'normal' NiMH AAs delivering a nominal 4.8 volts, would almost certainly be bricked if I put four 3.7 volt LiION cells (14.8 volts) into it!!

G'day Scoot + others

As I see it, you are quite correct in the presumption that if you use 4x Li-ion batteries you would zap the Pentax in a big way

I use these batteries [at least their big-brother, the 18650] in my cordless, 12v drill
The original Nicad batteries failed after one year; replacement ex-factory batteries were quoted to me at $65 ea, so I got 2 sets of 4x 18650 batteries for $40 delivered to my door and a bit of DIY soldering to make them into a 12v 'gang' and I have a new set of 12v batteries up and running

They last longer between recharges than the original batteries and with no memory issues should keep me going 'for years'

Hope this helps
Phil

Hello there, Phil and am pleased that my ISP seems to have corrected the fault/s that has plagued me for the last 24 hours or I would have replied sooner.

What really surprises me is that no one else has commented on DD's apparent claim that a cell with delivering 3.7 volts will substitute for one with 1.2 volts which can lead to the destruction of any device designed for 1.2 volt AA's - not to mention the fire danger!

I, too have a few devices taking expensive rechargeables and have cobbled together a number of Aldi's and Lidl's own-brand el cheapo NiMH AA's in series and series/parallel arrangements. Don't tell me - NOT recommended to connect these sort of cells in parallel but it doesn't seem to make much difference as my 'battery packs' are in fairly continuous use and therefore recharged often.

Thanks for your most interesting post, Phil in New South Wales..

It seemed fairly obvious that DonalDuc was making a joke. At least to me.
