I've had the same 12 eneloop pro AA batteries for over ten years and they are still stronger and better than ANY other rechargeables I have bought since. Never a single failure and each and every one is still in everyday use

Thanks for the review ! That's a very underated subject that is not enough discussed.
In Europe I use rechargeable Duracell HR6 NiMH 1.2V / 2500mAh
It gives me almost an hour of play when in my Tamiya quickdrive and has a pretty good shelf life.
I might give this product you presented a trial. Thanks again !

FANTASTIC review! Just what I wanted to see. I can now pull the trigger on the XTARs.

[michaeldorich]

This is a very thorough, useful and practical review. Thank you.

It seems to be very helpful in choosing AAA batteries. It's a wonderful video.

I bought the ISDT N8 8-Slot Speedy Smart Battery Fast Charger and that tells you the internal resistance of the battery. My wife uses AA & AAA batteries on LED candles nightly and kept burning through batteries, mixing good and bad batteies which just cause bad performance. Now that I showed her a bad battery IR rating, she seperates them and only uses good batteries. A bad IR would show over 1000 to 2000 ir. A good battery would show usually in the 200 to 300 ir. We typically use Amazon.

Not heard of xtar but seeing as our household is a high user of batteries I will be checking them out!

[ShenRC]

I like the Xtar batteries and chargers they always worked great for me.

I learned about the 1.2v issue when I bought some Energizer Nimh AA batteries for my Mini Maglite LED Pro. Fully charged, they were almost useless.

I'd seen the Pale Earth batteries all over Facebook, and was "this close" to buying some. I'm so glad I didn't

[pault]

The paleblue are specified correctly because 450 mAh * 1.5 volts = 180 mAh * 3.7 volts. If they are going flat, the problem is likely the quiescent current of the DC-DC converter is too high. These cells are actually the exact same thing as a USB powerbank. Only difference they are stepping the voltage down to 1.5V instead of stepping up to 5V.

[ValleyRC]

Apparently these work well in old toy grade RCs and give the fresh battery feel for the whole run!

Im currently using the white/ blue 3300mwh AA xtar li-ions. So far they available.

[Lee.gRC]

Very interesting info, thank you for sharing this,
It took me a while to actually notice that rechargeable batteries hold a lower voltage, and it took a while to find 1.5v ones and the price reflected it, but then I took notice in the difference in chemical compounds, where 1.2v are mainly Ni-Mh and the 1.5v where Li-ion

[trollk]

The AA Xtra batteries you showed are 2700 milliwatt hours(mwh) NOT 2700 milliamp hours(mah).They are not the samre thing.
Divide mwh by the voltage to get mah.In this case you get 1800mah.

This video saved me from making a costly mistake as I had just ordered a set of 4 Paleblue AAAs, though mine seem to be rated higher at 750mAh.
Yet, they look identical to be ones you have and I bet they've got the same problems.
Looking at their website it seems they have a new design which is rated at 600mAh.

Anyway, I cancelled the order for the Paleblue's and ordered the XTAR AAAs with the charger and an extra 4 batteries as backups.

[seadsejfovic]

The paleblue batteries, like all other rechargeable Li-ion batteries are very different from a regular AA battery. they have a built in buck converter to get the 5v lithium down to 1.5V, that buck converter is always on and drawing a little bit of power hence the bad shelf life. but the reason you read 0V is not because they are dead like would be the case for any other AA battery, its because the buck converter has switched off to protect the actual lithium cell. they can be recharged and will be good to go

[sxRamar]

I've used eneloop batteries and a Maha C9000 charger since they both came out. 😮

[KorrakotK]

I paired a normal 14500 lithium cell with a dummy battery in my electric sprayer and it works fine. 1.5V Xtar cells are too expensive.

New sub here. Thanks for your review. I have been using I think it is EBL batteries from China and they have mostly been okay. Have to recharge them quicker than I like. Lately the 1.2v limit bit me on some temp sensors I have in my outbuildings here on our Texas property. All of the 1.5v rechargeable ones looked okay but the octopus style usb charging cable seems unwieldy to me. So the XTAR have me curious. I think I am going to order some and give it a whirl. All the best from north Texas.
