Lowes has their house brand "Utilitech" alkaline 9 volt batteries priced at 12.97 for 12. I suspect that they are probably about the same quality as the big brands. But even if they are not quite as good how could you go wrong (unless they come apart and leak in your machine haha).
That would break down to $1.08 per 9V battery, and for an alkaline, that's good. They also list a price of $23.[size=small]97[/size] is the price for a 25 pack, which I have purchased in the past, and that's only 95.[size=small]88[/size]¢ per 9V alkaline battery.
I bought a 25 pack at Lowes in Salt Lake City, Utah in May of 2012 and used the last one from that package in a detector in May or June of this year. I was getting some banner support material and glanced at the battery display as I passed by going to the register. I was looking at AA batteries because I had nabbed several packs during a Christmas special in early December of 2011 on a Christmas ad-leader promotion of 30 for $4. Yes, thirty AA alkaline Utilitech batteries for only four dollars, making the per-battery cost of only 13⅓¢ per alkaline AA.
It was May of 2012 and I used them in several metal detectors, three or four flashlights, an electric shaver, TV/DVD/VCR/Mouse remote controls, blood pressure monitor, wall clocks, and other things as needed. I also gave a couple of 30-packs out as drawing prices in our monthly metal detecting group. I bought 6 [size=small](six)[/size] 30-packs in December of 2011 and 6 more packs in May of 2012. I never had an issue with their AA batteries.
When I saw the AA's in May at the same Christmas special I bought all six boxes they had left on the shelf, and needed some 9-V batteries and bought a 25 pack of them as well. At the time I had a Teknetics Omega and Tesoro Bandido II µMAX that used 9 Volts [size=small](one each)[/size], and I like to keep extra batteries in my 'Detector Parts Tote' that has extra coil/rod bolts, armcup foam and other things. I still have 2 or 3 of the 30-Pack AA's left but need to open one as my Detector Accessory Tote is getting low on supply. I am also out of 9V batteries and plan to pick up another 25-pack at Lowe's when I head into Portland this week.
I have had more issues with 9 Volt batteries, of various brands, over the past 40+ years of using them in metal detectors alone. During this span I have only had two problems with an AA battery. Most of the4 9V battery problems have been leakage or one of the battery connectors on top breaking off. I have used just about every major brand and a lot of 'bargain brand' batteries, even comparing standard batteries, those labeled Heavy Duty or Super Heavy Duty, and naturally Alkaline.
I ran some informal or casual battery comparisons back in the '80s after I bought a pack of Toshiba Heavy Duty batteries as a 'must buy' when I headed off on a several-day ghost town adventure in Utah and Wyoming. That was in '85 or '86 and I realized one of my detectors had a lot of run-time but I was out of spare batteries. A local store only had the Toshiba Heavy Duty so I bought them ..... and they ran, and ran, and ran! That made me question how much performance difference there was between brands as well as between the Heavy Duty and Alkaline labeled batteries.
I tested several brands and types and the worst performing/shortest use-life battery was the Ray-O-Vac brand. The best was very close between the Duracell and Energizer alkalines. Back then, some other I found, alkaline and heavy duty, came pretty close and cost less. During the past twenty years, especially when I was able to put in many, many hours of hunting every day, especially for 4-5 years after back surgery in July of '95, I have relied big time on the Kirkland house brand at Costco. Initially a 48 pack of AA alkaline Kirkland batteries cost close to $10, but today they are about $12.[size=small]48[/size] or $12.[size=small]98[/size] for a 48 pack.
Some folks question off-brand names, but I checked into Kirkland batter si and they were made for Costco by Proctor & Gamble ... the same folks who make the Duracell batteries, and in side-by-side tests the Duracell's and Kirkland's ran about neck-and-neck. Anyway, back to the Utilitech 9V's I bought. They gave me good run time in several detectors/brands, but I didn't do a side-by-side comparison. I never had a leak from and of the 30 9V batteries, and the only issue I had was with two of them. I used some in a detector that had tight-fitting battery clips and on two, the negative clamp-on contact broke off.
Longest lasting? No, but okay for the price, and not any real issues. Here comes fall and winter with more comfortable temps to hunt in, and my Bandido II µMAX will need a refill from time-to-time, so I will make a stop at Lowes this week. Later this fall I will also get as many different brands of batteries I can afford and set up an in-house comparison with detectors sweeping over dirt and targets non-stop while monitoring battery drain and run-time. I'll report back on that evaluation.
For now, 95.[size=small]88[/size]¢ for a 9V alkaline battery fits my budget just fine. Okay, I'm missing out on daylight and need to go wear down the current 9V that's in it now!
