2001年4月15日 · Take a look at the Energizer CR2032 product data sheet. (150kb download) Notice the pulse characteristics chart, they use 100Ω load to test the cell for 2 seconds. The depleted 2032 cells that I've tested will measure 3V open circuit, but drop drastically when loaded with a 100Ω resistor.

2003年8月11日 · IIRC, a new CR2032 is something like 3.3v. Three new AAA alkalines in series will be 4.8v. Two would likely work fine (3.2v), but by the time they're half-depleted it will be down to around 2.6v, which might not be enough voltage to power the scale. Even so, it will give more run time than a CR2032.

2008年3月25日 · A brand new primary lithium 3v will register about ~3.2v on a voltmeter, correct? The reason I ask is that my new Novatac is acting very strange. I pulled the Duracell out and it measures 2.85v. When I put a new surefire cell in, the light acts normally. 2.85 isn't fully depleted, is …

2002年11月16日 · It is a CR2032. Are all CR2032 batteries created equally? Do I just go to a Dollar Store or Wal-Mart and buy whatever I can find? I did find this article on-line? Is it accurate from what you know? If I decide to go with Duracell 3V Lithium Coin 2032 batteries, does it matter where I buy them from?

2003年4月3日 · With the other colors, you need a higher Vf to light them at full power (around 3.3 V) so two CR2016 batts are used. CR2032 and CR2016 differ only in their capacity and size. With two CR2016's in a cool color, the batt voltage is about 2.7 volts above Vf, and with a CR2032 in a hot color, the batt voltage is only about .5 volts above Vf.

2012年10月10日 · I was using 3v as a general number for my LEDs. The data sheet says 2.9-3.1v on the LED, so I picked 3v, when combined with a 100ohm resistor and a 4.5 input, gave me 18mA on the LEDs. The brightness difference between 20 and 18mA doesn't seem noticeable, to me, so i just ran with that math, plugging my number in, i get... Assume Vbatt = Vnom = 4.5

2004年2月16日 · Like others have said forget trying to light up an LED off a 1.5v battery source without a boost circuit, you either need one or change the power source to a 3v or higher amount like a lithium or lithium rechargeable format or double up on alkalines somehow.

2013年1月23日 · If CR2032 is safe, then BR2032 is even safer, with a longer shelf life before self-discharge and an even lower peak draw capacity. These things are pretty much capable of low-voltage low-current applications only, hence (mostly) safe. The device just won't power on and you'll wonder why if it's drawing too much current.

2018年4月17日 · I did this with another light/ battery combo. The cr2016 and cr2032. I more than doubled my run time by switching to a single cr2032, rather than a double cr2016. Ya, the light is not as bright which is fine. Thanks, just trying to get some different ideas before I spend any more money. These 392s every couple of days gets pricey.

2015年8月18日 · I was scouring the internet for Rayovac battery date codes for some NiMH batteries I have and the only list I could find was incomplete and ended in 2011. Rayovacs stamp was difficult to decode because their coding scheme seems to be random lettering in no order (except for the AEIOU and...
