I think a lot of this is over-complication. I have a box of batteries at home, mixed Energizers and DSE brand (orange and green), all NiMH, mixed 9v, AA and AAA. I have two five year olds, so the batteries go into doorbells, cameras, remotes, firealarms, toys, toys, toys, torches etc. all requiring 1.5v in various multiples. I am aware that the rechargables are only 1.2v. I have an Energizer recharger that came as part of a bundle. I haven't replaced or thrown out a battery in some years, literally. On the box of batteries, I have handwritten:

Only charge in matched pairs of similar strength.
Never mix strengths of batteries.
Only use good batteries in matched pairs (strength, brand and model).

Can't say I've had a problem with any electronic devices and I haven't had an urge to go out and buy alkalines or 1.5v batteries. The fire alarms go all the way to the DST change as recommended (I do test them about every other month) and the remotes, doorbells, remotes toys etc seem to last months on end.

I'd say - go for something midrange and manage the charge cycles well. My kids enjoy using a simple battery checker and 'hunting' for low batteries, then charging them.

Good luck.

On another note (and mods, feel free to move this to a new discussion if you think I'm hijacking this one), I've got a AA/AAA battery charger that also has a function to act like a powerbank and charge my phone (Galaxy S4)

I charged up 4 x AA Energizer Recharges (2450mAh) to see how well it would charge my S4 - the results were disappointing. At best it charged the phone very, very slowly - maybe 1% in 15-20 minutes. 

By my calculations rough calculations, 4 x 1.2V = 4.8V which is close enough to the USB 5V spec. The 2450mAh stays the same. Does this have any bearing on how fast it would take to recharge the S4? The S4 Battery is rated at 2600mAh. 

The slow recharge rate is really a black mark against the usefulness of the product. I really want something that will charge my phone in 1-2 hours ideally or keep it from going flat when in use.

TLD: I can't find a local supplier for the LaCrosse charger, but  Amazon has them for US$60.  I just ordered two of them — NZ$160 with shipping.


Presumably any battery chargers you'll buy from Amazon (or eBay) will have American plugs on them and will require changing or new adapters?  Sounds like too much trouble to me!  Shame there aren't any local suppliers that have already done the hard work.  Or do you just use a travel adapter?

So is this Sanyo Eneloop XX 4 pack on Amazon the same as this Sanyo Eneloop XX 4 pack from Jaycar? If so then it's cheaper and faster to buy from my local Jaycar store.

I use the white eneloops. With Maha C801D you can just swap a standard power cable in (the little figure 8 one from memory), the C9000 from memory has a plug pack. You'd probably just need the physical adapter, most work with 110/230V.

Ah yes, I see how the adapter works on the Maha C801D, in fact they advertise is as being worldwide.  I'm sure I've got a spare figure 8 cord somewhere, otherwise they're cheap to buy.  I think I might have to spend some of my Amazon credit on one of these.  Thanks!

He is cheaper than recharged.co.nz although his range is smaller and he charges for some things that are included with recharged. For example He only has PowerEx in AA, everything else is Imedion (not necessarily bad). Also all my batteries from recharged have come in the plastic holders, he sells them separate. They're actually very handy.

I'm interested in how you are using them?  Are you talking about single AA for phantom power in something like an NTG2, or transmit/ receive power in something like a Sennheiser G2 or G3?  I must admit I've never really looked into it, but I always use reasonable quality alkaline in all my sound gear from phantom power through wireless and including my field mixer.  I even use alkaline in my Pocket Wizards, and this is despite having heaps of rechargeable batteries. 

I think I'll go ask the lads on DVInfo, because if they work OK, it would definitely work out way cheaper, but I'm thinking it would compromise battery life.

Borrowed the Maha C9000 from Timmmay during this weekend - still going through the last four batteries but as expected all my old Energizer batteries are basically good as dead - all rsulted in "HIGH" status (meaning high internal resistance, good for disposal). Also a couple of Panasonic AAA had the same results.

A couple of Enitime batteries are still good - taking them through a cycle now. The Eneloop batteries I have have here all tested well and are charging as well.

Now to get a few Eneloop AAA for the Amazon Fire TV remote (the only electronic here using AAA really).

Sometimes if you put the batteries into a "dumb" charger it will force charge in and wake them up, but there's a risk to that.

If you have a good charger and refresh your calls every so often (6 months/10th charge) they last aaaaaggeess.

These cells are probably around eight years old now... Not worth it the time I think.

I've just bought a pack of eight Eneloops last month so that will be a good "refresh".

I managed 5-6 years with good treatment, but they were well used in high powered flashes. At 8 years they're ready for the bin.
