Electronics, Lighting, & Gadgets - Rechargeable AA (for Dinotte 200L)

Best ones out there? I use commerical store brands but run time isnt that great... appreciate any help. thanks!

I swear by Eneloops. Costco carries them in a multi-pack with a charger for $28 here.

Eneloops are great for holding a charge for months, but they are smaller capacity than normal batteries.

I use regular Duracell 2650s with a $11.00 mini-charger. I get over 3 hours on Turbo mode when the batteries are reasonably new. I got a new set after about a year. The old ones still work, but they make the red low battery light come on after 15 or 20 minutes, even though they still last at least an hour or more. So they are my spare set now.

See my review (http://www.bikeforums.net/showthread.php?t=357328&) from last year.

Maha Powerex 2700mAh NiMh AA

And they hold a charge for a long time too.

Maha Powerex 2700mAh NiMh AA have had some good reviews especially on capacity.

+1 for Powerex

What are the chances that MAHA does not really make or design the Powerex?

What does that have to do with anything? Do you know of a battery that compares?

exactly. it doesn't matter.


eneloops rock. even though they have a lower rating, 2100, they run great and are easy to
leave laying around for weeks and grab them and they don't fall flat like a regular rechargeable.

same with MAHA Imedion. rated 2100 but don't just stare at that number. the real world use of the
battery is great. u can have a 2700 rated AA and it can still die sooner than a 2100 eneloop will.





anyway MAHA makes their own batteries....so there....

I have Sanyo's non Eneloop (http://www.thomas-distributing.com/sanyo-2700-aa-rechargeable-batteries.htm) model and they work great.

I like the duracell 2650's and Titanium Brand 2700's..

Its all about business. MAHA has a business strategy. It either makes it own or doesn't. MAHA may put in their engineering and send it out to a battery manufacturer. The consumer wants to know for the price what he is getting. Just like those Sanyo batteries.

How is this a bad thing? Do you think they are out to screw you?

Never said it was a "bad thing". In the olden days when I would buy blank CD's there was a perception that certain brands were somehow better than others. But I also found out that some CD's were manufactured by the same company but branded different. The name alone allowed a pricing premium passed on to the consumer.

Which brands do you think offer the same quality, capacity, and low self discharge as the Maha at a better price?

There are even worse examples. There was a case where a company who made contact lenses sold what was supposed to be two different lenses with one costing more than the other. It turns out the only thing that was different was the packaging--exact same lenses.

Even if MAHA did sub their manufacturing out their batteries are good quality do the company they subbed out to is decent.
Supposedly for low self discharge batteries there are only three places making them, one in japan and two places in china. The japan one makes sanyo eneloops and others like the rayovac hybrids are made in the china plants.

I have Sanyo's non Eneloop (http://www.thomas-distributing.com/sanyo-2700-aa-rechargeable-batteries.htm) model and they work great.

I have these and PowereX 2700 and think the Sanyo 2700 are longer lasting. Both are good. The Eneloops are only necessary if you don't ride often. I ride in the dark all winter long so I want a longer lasting battery. I recharge everyday. If you ride often go for the more powerful battery.

FWIW,in discharge tests of the eight Sanyo 2700 and eight Maha Powerex 2700 the Maha have always come out on top as having more capacity. I'm using a Maha C-9000 charger to do the testing.

Both are excellent but I see the difference everyday when I ride. I'm using 2 Fenix LD2 Q5 to do my test. I would not hesitate to buy ether one though.

Funny enough I had the exact opposite results with my LD2! Maybe one of us has a bad cell somewhere.

So, if the Mahas or Eneloops are the best, what's the best value rechargables?

They both are rechargeable. Take your pick depending on your needs.

awesome.. I had expected 2-3 responses but nothing like this.. thanks.. I ll check out the Mahas and will report back how I like them.

I have been using the Powerex 2700 for several months. I love them. They consistently charge to something well in excess of 2700 - 2800 to over 3000. But they are very close to each other when I charge four at a time.

When I first started with rechargables I bought a gross of Energizer 2500. What a piece of crap. I see Energizer still sells NiMH batteries but I don't see the 2500mH capacity as much. I believe the issue was with this one capacity point and I recall reading that it wasn't just with Energizer but with all brands.

I vote for Powerex and I really like my Lacrosse BC-900 charger.

The Eneloops are slow discharge. They hold their charge for a long time while sitting idle. Sanyo makes them. Sanyo also makes a 2700 as does Powerex. These batteries have a higher mAh so will last longer while you are you using them. However they discharge quicker while sitting idle. SO if you often ride at night get one of the 27oomAh but if you ride occasionally then get the eneloops.

Do not neglect to get a decent charger. The highest capacity batteries in the world will not perform well if they are not fully charged. I've found that the cheap $10 chargers commonly found are OK if all one needs is some charge in the battery. However, for consistently good charge performance, the Maha 800S, 801D or 204 chargers are well-regarded and doesn't cost too much.

only eneloops for me

any other type just loose charge sitting idle. you only get the benefit of high mah if it just came off the charger. after sitting a couple of days your not really getting 2700mah after a month or so its discharged to almost nothing. not with eneloops it can sit for a year and hold charge.

as for battery chargers MAHA are the best as their high end models charge and monitor each cell during charge toping off "each" individual cell to capacity.

the cheap chargers will batch charge a set of cells and if it detects a high voltage on one cell it shuts off so you'll more likely have an unbalance charge state on the set. thats not good. you'll end up riding in the dark

Not only that but some chargers that charge one at a time and charge slow enough to not cook the battery can still not be a good charger. I wastes $30 on a rayovac PS4 and wondered why my batteries weren't lasting very long until I found a web site that said it terminated the charge too soon and didn't fully charge. I verified myself and it was only putting around 75% in them. The couple that with high self discharge of the batteries they were too low within a few days to power anything.
