Battery Life

[Ty Ford]

Hi,

I was recently talking to some folks who have tested a lot of batteries on
their gear. They said Varta was the longest lasting and that they saw no
difference between the Duracell and Duracell Pro.

Any comments?

maybe it depends on the country and stock , but they last less then
Energizer and lees then the Duracell
on 400 tx they last about 4+ hourse , the Duracell about 4.5 + and the
Energizer about 5.-5.5
but since they about 60% in price here they are much better bang for the
buck
another thing they stand much better then the Duracell in hi ampere drain ,
but still don't enough for 201 receivers witch only loves the energizer for
less then 3 hours :-)

Oleg's numbers agree with ours on the Eveready and Duracells. We have
not tested the Vartas.

In their jobs, are the batteries pay for you or for the production?

So the Engergizer is the way to go? I am the verge of buying a gross of
batteries (9V)--any other opinions? I always thought the ProCells were
the best---

Urban Myth?

I always understood that the ProCells were just regular Duracell
repackaged for quantity distribution.

I'm trying to post from a different computer. Sorry if this shows up
twice. Am on vacation for two weeks.

Energiser lasts about 10% longer than Duracell in load tests on our
transmitters and receivers. Our transmitters will suck a battery down
in about 5 hours. Duracell told us that the batteries are not optimised
for high drain applications the way the Energiser is. As I understand
it, Duracells will do better at medium loads though we have not tested
that.

I've had great experiences with Energizer Industrial 9 volts, AA's and
AAA's. You absolutely cannot beat the pricing offered by Westlake
Electronics in Seattle. So low that it's worth buying online and paying the
shipping.

I don't have access to it at the moment but somebody keeps a battery
comparison page on the web. Varta, IIRC, isn't the shiniest star.

I get the Energizer Industrials for .95 each and they last well over 4 hours
in my Lectro 205 transmitters. No way a lithium battery is a better deal
especially because there isn't a good way to judge how much life is left in
the lithium you used for a few hours one day and few on another. Maybe you
number yours and keep battery logs...but I just plop in a brand spanking new
.95 cent battery every time I tag someone with a wireless and change it at
lunch if they are wearing it all day. For me, lithium's are only used when
the transmitter has to be on and unattended for more than 4 hours...or when
I'm using my 250mw transmitters.

My two cents.

John,

Which 9v do you recommend ( EVE-L522FP LITHIUM 9 VOLT)? And what charger do
you use for those? (Having a tuff time finding the chargers for Lithium).

Thanks,

Richard

[remoove that shit@netvision.net.il Oleg Kaizerman]

you cant charge 9v lithium's
that's one time battery

Also, the lithiums can swell when discharged--- be sure to take them
out at the end of the day or you may need a cork screw. I have had a
couple last 10 minutes. Do they degrade once the pouch is opened? I
took mine right out of the package and got twn minutes-- maybe there
was a pinhole in the package?

George

[Philip Perkins]

When I'm working alone I pretty much only use Lithium 9v
batts in the transmitters these days--their longer life means that I
can change the batts when convenient rather than
have an Alk battery die at some inopportune moment.
Ditto for mic power supplies, Denecke sync boxes, and
wireless RX that I use for links to miniDV cams w/o power taps.

It's a 1/8 trs right angle connector! Unlike the ones we all have on our
beta-snakes (molded housing), this is just the connector, so when it gets
damaged, you wont have to replace the whole molded connector/cable.

Do a search on the Westlake Electronics website for SWI-35HDRANN
SWITCHCRAFT and make sure you switch the 2nd pulldown menu to "match all
words"

Canare also makes an awesome 1/8" straight (mini-phone) stereo
connector-- may be too fat for tight quarters. Works with BetaCams and
DSR-500 for sure. Has nice strain relief with fancy spring. The best
one I have ever seen.

But I digress.....

Way too much work for something so easy to fix. Go to Radio Shack and
get their 1/8" trs headphone"Y" connector cable assembly, about 3" long
for maybe $5.00.

Male goes into camera, return in one leg and the other leg for cameraguy
to plug into if he wants. Point is, if gorrila camera op yanks the
return he's not going to ruin the connector on your snake.

Thanks guys!

I think I'll be placing an order with Westlake for the industrial 9v alkys.

Panasonic is introducing a new disposable AA and AAA battery called the
Oxyride
(Oxy-Nickel Hydroxide). It is supposed to cost the same as Alkaline and
offer about twice the life. Anyone tried any of these yet? They have a
long shelf life but are not rechargeable...

Here is more info on the battery.
http://www.panasonic.com/consumer_electronics/batteries/Oxyride_Battery.pdf
So far only Panasonic is using this chemistry.

Their Literature says it performs well with High Current draw equipment. But
the yeald drops somewhat to about 1.5 times as long as Normal Alkaline.

You will be happy with these batteries...I've never had a dud or an issue
and they also come packaged with the little black plastic snap on caps which
I like.

You must have a VERY cheap source for Lithium 9V batteries (or a very
expensive one for alkalines). In my experience the Lithiums cost
$5-5.50 each and run, yes, about 3X as long as Alkalines -- which
usually cost $1-$1.50 each. In other words, 3X the battery life for 5X
the price.

For bang for your buck, alkalines are definitely more cost-efficient.
The real beauty of the lithiums is that there are many situations where
you can't change a battery easily whenever you want to, and don't want
to have to stress about the battery in a transmitter running low.
Charlie talks later in the thread about "changing a battery at lunch"
that has died after running 4+ hours, but on a feature day 4 hours is
still 2 hours away from lunch. That means if you've wired someone at
the beginning of the day and left them wired all day, you're going to
have to get up into their costume mid-day to change a battery. On some
sets and with some actors (and depending upon the complication of the
wiring process) this can range from a mild nuisance for everyone
involved to an absolute no-no that will quickly put you on the s***
list of folks you may need some favors and help from later. Enter your
savior -- the lithium 9V. Put it in at call and forget about it.
Check it at lunch -- if it's 8.7V or above at lunchtime it will be good
to go for another eight hours. I've done this for years with no
problems.

Another helpful place the Lithium 9Vs come in is Comteks. Because of
the light draw, I can generally get a full week's use out of one
lithium 9V in a Comtek receiver, which means a lot less battery
checking than if I have to use alkalines. I can put them in on Monday
and not have to take out the multimeter until Thursday. No fuss for
me, and no "courtesy listeners" running up to me mid-take while I'm
trying to mix, complaining that their Comtek battery is dead.

The lithiums are more expensive...and well worth it, if you work on
features.

They do, but more significantly the Duracell is slightly shorter such that
in gear that has spring contacts using other longer batteries can leave the
terminals to which the battery connects bent enough that they no longer make
good connections to the shorter Duracells. Comtek receivers are one good
medium load example. This is one reason Duracells are so widely used.

Both these vendors publish manuals with detailed specs regarding various
loads for their products by the way...
