I've not ever seen a single thread on CR with as much consensus as this one.  I think I know what I'll purchase next for batteries...

I have a LaCrosse BC-700 charger.  It makes me happy every time I use it.  I might possibly be a geek, though.  I guess it's expensive for a charger, but it's less expensive than a nice UV filter and negligible compared to most other camera gear.

I use Eneloop batteries, sometimes Pro and sometimes regular.  I can only agree with what others have already said about them.

I'll add to the Eneloop chorus.  I use the Pros, no problems ever.  I've been using them for around four years or so.  For chargers, I use Pearstone, which later got rebranded (?) to Watson.  B&H has them.

I have the Technoline BC1000 charger and about 30 Eneloop Pro rechargeable batteries and was wondering what setting would be best to charge at?

I'm never usually in a rush to charge them so would be looking for the best setting for optimum power retention and battery longevity.

I see choices for 200mA, 500mA, 700mA and 1000mA when charging 4 batteries and also for 1500mA and 1800mA if charging only two batteries.

I think I know the answer to this even before I asked as the lowest rating will probably be optimum when time is not a priority but thought I'd ask the question and see what you Eneloop experts recommend.

There are four modes of operation according to the manual, Charge, Charge/Test, Discharge & Discharge/Refresh 

As the batteries are brand new & unused which mode should I use the first time around?

And when they are in use which mode then or should I alternate the process?

The intended use will be in Canons Speedlite system including 600EX-RT, ST-E3-RT, MR14-EX II along with some battery operated candles and a couple of soap dispensers that chew through batteries like they are going out of fashion! :)

Thanks & kind regards,

Charger Technoline (LaCross in USA)

Batteries Eneloop & Eneloop Pro.  The plain vanilla Eneloops have many more recharge cycles, the Pros hold about 20% more capacity.

There are some alternative to Eneloops though.  On the following link, someone tested a boat load and posted the results, BUT recharge cycles are another thing entirely.

Regarding Eneloops..  there are fakes around, DO check up on your source, some are cheap for a reason.

I power my Yongnuo 600s from eneloops and they just work for ever on them.

Always aim for a 4hour recharge time.  Faster = bad for the battery, slower = charger can miss the "end-of-charge rate-of-change of charge-voltage" and end up overcharging them (bad for the battery)

I'm using the  La Crosse Technology BC1000 and the only fault I find in it is that if the battery (eneloops...) is drained the charger will not recognize it. I need to charge it in a simpler charger for 10 min, or so, and then move to the  BC1000. Anyone else sees this?

yes

or you can briefly short a good battery across the terminals of the "dead" battery (+ to +, - to -) which will give the cell a small charge and get it recognised..  the good battery will have about 1.3V on it, the chargers put between 1.3 & 1.5 volts onto the battery, so it's at the safe end..  you won't start a fire or kill the battery or anything.

The charger just wants to see a bit more than some low voltage to "prove" there's a battery present.

Exactly same for me too, just jump it with another battery for ~5-10 seconds.

A clone of this thread seems to pop up once or twice a year. But it remains a valuable question. Which AA's?

Over time I've had equally strong performance from Eneloop Pro's and MAHA Powerex. They all get charged in a smart MAHA MH-C801D 8 cell charger. By strong performance I mean decent life from full charge while on a job and also longevity which is measured in years. Honestly I can't split the two. When I get new AA's, I write the month and year on the cell with a Sharpie.

For extended projects or ones where very rapid recycling is a priority, I hook up to an external power source as well. I used to run with expensive, utterly reliable Quantum Turbo T3 batteries but have switched to the remarkably good Godox Propac PB-960's that came with my pair of Godox Witstro AB360 flashes. A $10 cable connects the pack to your Canon Speedlight. It's light, has a belt clip, two power outlets and probably exceeds the performance of the Quantum Turbo T3.

I used to buy brand name ones. I have since switched to the amazon brand. They are around 2300-2500mAh.
I purchase about 30 and they are all still working great after approx 1 year.

I have switched from eneloops to amazon basics too.  They are amazingly cheap, and seem to work great.

Just a late and minor addition concerning reliability.  Some of my rechargeable AA batteries are pushing 10 years old now.  I have learned this:

1) No Eneloop has ever failed for me, though some test with 10 or 20% less capacity than when new.
2) Another brand (Ray-O-Vac?) did have a few failures, but only after several years - probably 5 or more.  This was out of about 24 bought to drive a home-made LED ring flash, and probably not treated very well.

My policy is:
  • Shooting underwater in a place I may never get back to: nothing but nearly-new Eneloop pros.  One set in the flash, one safe and dry.
  • Fairly serious photo trips: 8 Eneloops, any model (I never need more than 4 at once).
  • Maybe I'll want the flash today: 4 Eneloops.
  • Around the house: whatever is handy.  They all work.

Admittedly, I'm not a pro.  If my income depended on batteries I'd have more backups.

I use Powerex AA - newer batteries hold 80% of their charger for about a year and are rated 2600 mAmp

AmazonBasics - the 2400mah high capacity ones.  You can get them on subscribe and save for 10% off (if you buy a total quantity of 5 items of anything for that month's subscription).

I have a stupid number of them, more than 100; they work just as well or better as Eneloops, my previous brand of battery.  I tried the Amazon ones on Prime Day or some such, when they had a big sale on all AmazonBasics stuff, and found that the flashes with the Hi Capacity AmazonBasics lasted about the same number of flash cycles as Eneloop Pros at 2550 mah.  But, they cost less than half the price.

The power retention on them (when you just have them sit on a shelf) is good too.

I use them with 600EX-RT's, both Canon and Yongnuo, and with E3-RT's (where they last a very long time).
