[quote=fourlocks]Wow! Aside from cameras, I fly radio control aircraft and I'm an instructor for people just starting out. Many transmitters use AA batteries and weak batteries can turn a $500 aircraft into an expensive lawn dart if the signal strength drops off too much. I'll pass this on to the members of my club because students often ask me which battery they should use.

If you ever find yourself down in Jawja, visit us at CCRC (https://ccrc.clubexpress.com/content.aspx?page_id=0&club_id=438730&sl=600100472) and/or PCMA (http://www.pcmaviation.org/).

I saw this Wirecutter review when it was last published. At the time I needed more AAAs so I bought the EBL 8 pack from Amazon. I am in no position to rate them vs my supply of Eneloops but the price was nice! Since I make it a habit to check all my battery operated items at least once a year and refresh them with fully charged batteries I will never be able to tell which is better. AFAIK I have never had to discard an Eneloop so I'm not exactly a power user! But I sure have saved money over buying those huge packs of Duracells at Costco.

How in hell did RC airplanes, sailboats and submarines get in this discussion?

Or, maybe you'd prefer Energizers.

There isn't a great deal of difference between them except for price and mAh.

I need more batteries, so I'm looking for comparisons.

I've been buying "Amazon Basics" lately, and they seem to be fine. Most of my cameras use dedicated rechargeables nowadays. The comments about Eneloop are certainly true---but as observed, most battery technology has kept up.

Actually I just get Duracells.
Never had a problem with them.
And years ago they lasted longer than other brands.
So I simply stayed with them.

I used Duracells until I had more than one leak. They no longer have a place in any of my gear.

Because the subject is "AA Batteries"!!!!! (It doesn't specify for what purpose.)

It should be noted that the fully charged voltage of rechargeable batteries is not high enough to operate some devices. They are 1.2 volts, as compared to 1.5 for alkaline batteries. However, the alkalines have dropped to around 1.2 volts by the time they are 50% discharged.

Nope! An alkaline measured without load at something like 1.4V is dead.

Not true!!!

"Notice the voltage reading on the voltmeter. If the reading is more than 1.3V for alkaline battery (not rechargeable battery) then the battery still has some juice left in it, don't throw it away. Otherwise, properly discard of the battery."

Panasonic Eneloop for me...use them in my flashes. I have an SB-700 and an SB-5000. Both chewed through normal alkaline batteries in a few hours. I've had a set in my SB-5000 for over a year now and use it often...I can't believe how long they last. Their shelf life is amazing as well.
I bought 2 sets with a charger a few years ago.

I like chargers that let me charge one or three batteries.

Yes I do too but not because I need to charge one or three batteries but the charge current should be for individual cell as their remaining charges are different.

The chargers I use will charge 1 to 4 batteries - independently, with a light for each.

I have a LaCrosse charger that has a little information window for each battery. I'm assuming that it does a better job than the standard 4-battery charger.
