Panasonic builds record-breaking battery
January 16, 2008 - 11:09AM

Japan's Panasonic has created the world's longest lasting alkaline
battery, according to Guinness World Records.

Panasonic promises its new Evolta battery cell - whose name is derived
from evolution and voltage - will keep gadgets running 20 percent longer
than offerings from rivals Duracell and Energizer, as well as its own
upscale Oxyride batteries.

Guinness certified Evolta in a Tokyo ceremony Tuesday as "the longest
lasting AA alkaline battery cell," based on testing under guidelines set
by the industry's International Electrotechnical Commission.

The battery also has a 10 year shelf life, making it suitable to store
in preparation for disasters. Other batteries have about five to seven
years of shelf life, according to Panasonic officials.

Evolta goes on sale in April in Japan, and is planned for overseas
markets later this year, according to Matsu****a Electric Industrial,
which makes Panasonic brand products.

The batteries will cost about 590 yen ($6.30) for a pack of four in
Japan, or about 15 percent higher than regular batteries and 3 percent
higher than Oxyride. Prices in the US and elsewhere aren't yet decided.

Matsu****a, set to become Panasonic in October, plans a major marketing
drive for Evolta. It still has a minimal share of the U.S. market in
batteries, and hopes to raise that with Evolta. Matsu****a has sold 700
million Oxyride batteries worldwide so far.

I've switched over to AA rechargables entirely.

2 amp types last 200 to 500 precent lomger than non-rechargable alkalines.


That covers my camera (4 AA) 2 sets of powered speakers (4 AA each) an
iHome for my iPod (Merry Christmas!) (4 AA) and a pair of AAA each
for my hand held VHF marine radios (3 of them).

In addition, I purchased a 10 cell battery charger pack (iSun) that
plugs into the solar cells on the boat. AA and AAA cells recharge now
without draining the house battery or using an inverter to drive an AC
adapter.

So while a 20% increase in life of an AA battery may be fun for
Panasonic, I don't think I'll be buying any of them...

Are you aware of the new Eneloop NIMH that Sanyo recently brought out?
They apparently have solved the leakage issue..they dont go dead
sitting in the drawer. Ive been changing over to these from basic
NiMN bats, as Ive charged the old style, and a month later tried to
use the digital camera, only to find em deader then a popcorn fart.

These go a long time without bleeding down.

Interesting, Sanyo have solved the 'must work out the draw issue'. I
still dont see them replacing the backup set of alkalines in the
grab-bag for the handheld GPS. (the Handheld VHF has its own spare
Li-ion pack).

I dont know if its cost effective to go rechargablethough as we seem to
get through abut 30 AA alkalines a year (a UK chain 'Halfords' do a 30
pack) and they seem to last at least 80% of a Duracell's life at 2/3 the
cheapest online price and less than 1/2 of the average retail price for
Duracell. Its tough to beat most of the performance for a small
fraction of the price . . .

Mm, yes - its getting to be a major problem in this household, SWMBO
has a digital camera, as do I - nimh seem to have a relatively short
useful life, exacerbated by my wife leaving them in the charger
cooking until her camera ones go flat....and, as you have observed,
they seem to self discharge pretty fast, even tho thats not supposed
to happen with nimh, nicads, yes.......got to the stage theres a pack
of alkaline AA's in the drawer, and in the car , for when the "you are
responsible for this" (somehow) cries rend the air.......and as for
her resetting the date/time thingy on her camera, thats my
responsibility too...

I got an OLYMPUS FE270 for xmas, it takes a nice picture, but the
manual is bloody hopeless - I am SURE the one I played with in the
shop had variable shutter speed, and it did the aperture thing itself
- cant find it in the book, or the CD.....made sure it had a decent
macro setting for project pictures. That werks ok, thankfully.

Its very cost effective to go rechargaable for me, as I use a digital
camera a LOT. Also handheld comms and flashlights and....

A charger and a basic load of batteries, particularly off Ebay is very
inexpensive.

Great, if it's from Panasonic a.k.a. Matsu****a, about 33% will have
failed before you even open the package and another 33% will fail within
a week. The remaining 33% will work properly, but you'll be so disgusted
with the lack of QC that you'll never use a Matsu****a product again.

What do you mean by "last 200 to 500 percent longer"? Rechargeable alkalines
have about half the amp-hour capacity of regular alkalines. Do you mean
their entire service life is 2 to 5 times longer? If so, you should be
getting much more life out of them than that.

I use them for a few things, but the low amp-hour capacity is a problem for
some applications.

I have alkaline batteries in the weather station display, the
indoor/humidity sensor, and all the remote controls. These are low draw
applications where swapping in charged NiMH would be a PITA.

My digicams, GPS, Maglights, FM transmitter (for mp3 player) and such use
NiMH and I'm very pleased with the performance.

A flashlight kept in the car for emergencies should have alkaline batteries
along with a transistor radio for emergency listening during a power
outage.

There is Rayovac Hybrid too. See:

http://www.rayovac.com/recharge/hybrid_technology.shtml

I've been playing around with a set of four AA size now for
several months. They seem to work okay. They had a decent
life span right out of the bubble pack similar to the
average alkaline.

The local store (Meijer) where I bought them dropped all
Rayovac batteries just recently. Don't know what is up with
that, but I think it was because they now offer their own
house brand. I noticed right off that the house brand has no
mention of any kind of warranty on the package. I won't buy
any batteries that won't replace stuff that is
ruined/damaged by them leaking...

You'd better do some more research, Richard. A new-technology RAM
(rechargable alkaline magnesium), the best of the lot, may be rated at 2.2
Ah the first few times, and if your drain rate is 30 mA. But at those
parameters a non-rechargeable will deliver a lot mo 3.0 Ah or so.

If you draw your RAMs down all the way, capacity falls off fast after a
dozen re-chargings. And a drain rate of 300 mA on a Pure Energy brand AA
cell (latest technology rechargeable) will give you only around 1.2 Ah
capacity:

http://www.pureenergybattery.com/press/oemguide2007.pdf

As far as I know, no rechargeable alkaline has reached the capacity of
primary (non-rechargeable) alkalines, even when they're brand-new. Unless
you use them in a capacity-limited application, where you're never drawing
them down to less than 75% of capacity, their capacity will start to drop
significantly after a dozen or so recharges. To get performance and long
life out of them you have to really limit the percentage of their capacity
that you use.

From your figures it looks as if someone is comparing the perfect-case,
first-use, very-low-discharge-rate capacity of a Pure Energy rechargeable
with a Chinese primary alkaline operating at ten times the drain rate. d8-)

watch the quality drop on these batteries. If they're not stamped "HR" on
the bottom, they're not the high quality Sanyo cells from Japan they've
usually been selling. They'll be changed to some sort of no name garbage,
and the process has already started.
