A 6-pack of duracell 9V costs $35 at a home depot in Chicago. But I can buy 24 bulk-packaged Procell 9V for $45, shipping included? Is this real? What am I missing? Have I just wasted an insane amount of money over the last three years?

About the same price at Gaffers Tape Gaff Tape when you add in shipping.

Stuff like batteries is where retailers make up for the loss leaders on the aisle end caps. There is always a better online deal for them.

That's actually kind of expensive, even at $45 per 24 pack. If you can withstand case pricing, you're looking at about $1.10 per 9V and $0.41 per AA for Procells. If you're ok with standard models, even less.

How are the recycling facilities for batteries in the US? With so many of us plowing through a household's yearly consumption of batteries in one show day I feels it is proper for us to be good role models and recycle our batteries (I try to anyway).

I get my AA's and AAA's form IKEA £1/$1.56 for a pack of 10 reasonable alkalines. That's roughly $0.15 per AA.

We have been using these rechargeables in our Sennheiser G3 IEM and G3 and 2000 mic systems for well over a year. Battery charge indicator on the Senn stuff indicates slightly less than a full charge on a fresh battery, but discharge life is still comparable to Duracells we used previously. We have been very happy with their performance, cost effectiveness and environment friendly footprint.

Re: Batteries pricing online, I can't believe my eyes....

The thing to remember when comparing rechargeables to alkaline is two things, standard rechargeable batteries have a slightly lower voltage output (1.2v vs 1.5v) this won't normally cause a problem but may affect the battery monitoring circuitry and may cause problems if the circuit is expecting batteries with the full 1.5V. The other thing is that while in low drain devices an alkalines life will be comparable to a similarly rated Ni-MH in higher drain devices (digital cameras are a good example) the capacity of an alkaline drops off considerably and will have much lower life than the same Ni-MH rechargeable (even cheap 1300mah Ni-MH batteries will vastly outperform even good alkalines in higher drain devices). Also to note is that some Ni-MH have high self discharge rates and don't store very well.

On the original note about prices: Yes, you have been gouged, but that's consumerization for you. It's always better to buy bulk for batteries if you can.

About rechargeable batteries: I have been spending plenty of time lately on researching batteries; the biggest thing to understand about both alkaline and NiMH/other rechargeable batteries is that it all depends on the electronics you are feeding power to. After that, it's as easy as high school math to figure out what will happen nominally. Find out the drain facts before anything else if you can.

We sell the Energizer Industrial batteries here at my store.
Over the counter they sell for $1.64/ea. (9v)
It is the same Energizer battery with there *industrial* label on it and it comes in a bulk pack only (No blister carded packaging).
The AA battery sells for $.44/ea.

All of which can be discounted when purchased in bulk.

So my advice would be to find a local Electrical Supply house in your area and see what they will sell you batteries for.
 
Re: Batteries pricing online, I can't believe my eyes....

The only thing to watch for is to make sure you're not buying old stock of batteries. When you buy them in the store, you can see the date stamp on them. When you buy in bulk from some website, you don't necessarily know what you're getting. And of course, there is also the off chance that an online store is selling counterfeit batteries as well.
 
Re: Batteries pricing online, I can't believe my eyes....

If I have time or plan a head, I tend to search eBay or Amazon. The last few purchases of 9v & AA have been from medicalproductsdepot; $15 for a 12pack of 9v Duracell Procell.

If I don't have time, I stop at BJs and pick up the 6 pack for $13 and sometimes I have a coupon.

The MaHa Powerex AA usually meter at 1.4v direct from the charger. The battery telemetry in Sennheiser SK5212 belt packs is accurate and they last around 5-6 hours.

I've always used Big Green Box for battery recycling.

From what I'm aware of, getting 1.4v out of them probably means we're overcharging them, as I seem to get the same thing when I charge my Duracell ones.

It's possible. I've heard and tried all kinds of charging and conditioning methods. It doesn't really seem to make a lot of difference. We alternate shows so each set does four shows a week. We condition each set every two-three weeks. We get about 9 months from each set and then start seeing some anomalies. Once that happens we replace the entire set.
