This product does not contain Mercury(Hg), Cadmium(Cd), nor Lead(Pb), and conforms to EC regulation values. Murata-unique sealing structure, coupled with special sealing-material treatment, has helped accomplish the excellent leakage resistance. Stable voltage output is available during the high-drain pulse discharge. Excellent stable discharge and high-drain pulse discharge characteristics.High cost performance has been achieved owing to the use of manganese dioxide as a cathode material. Choose Energizer specialty batteries for long-lasting power you can count on when you need it. And these zero-mercury coin batteries can hold power for up to five years in storage. It delivers long-lasting power to your button-battery-operated devices, from household electronics like keyless entry systems, to e-books, toys, calculators, and watches, to heart rate and glucose monitors. ![]() You can get the durable, reliable power that keeps going with this Energizer 357/303 Silver Oxide button cell battery. The IR44 battery can be utilized in many devices such as watches, motherboards, and a variety of medical devices like thermometers. The IR44 battery is typically a 1.5 Volt with an operating temperature ranging from 0☌- 60☌, while optimal temperature is 20☌. The IR44 battery is an Alkaline Zinc Manganese button cell battery. Silver Oxide Batteries vs Alkaline Batteries This article will answer your questions and show you their similarities and differences, as well as the interchangeability. Since they all look the same, can they be used universally? I was thinking maybe it's something to do with the potentiometer from the ISO/speed wheel and its interactions with eachother, because it's the only thing I can think about considering that, even if the lightmeter was uncalibrated, it would at least behave the same if half the light was cut.LR44 batteries and 357 batteries that are round, flat, and look like small silver buttons seem to look the same. This way I can see if there's some pattern for me to adjust accordingly or if it's indeed unstable What I'll do is: photograph using a handheld lightmeter, write the values down, and also write down the values shown in the camera as well as where the needle is sitting Even now I think it's mostly usable with some eventual corrections My lightmeter was apparently not super precise but usable a few weeks ago. I compensate this difference through the ISO setting (informing the camera a value ⅓ stop above: iso 125 for a 100 film) If film was "so precise or else it would be ruined" the lightmeter on my Pentax K1000, for example, would be a minuscule slit where the needle would have to fit perfectly in reality the ideal zone given is around a full stop and a half (and I've always metered perfectly with it), so don't sweat it, it's very forgiving The contact is stable and working fine (the battery indicator shows it's at its maximum) – also, as I've pointed out before, the 0.15v difference is negligible (⅓ or ⅔ of a stop), especially considering how film has an amazing range for over and underexposures. I'm using the LR44 battery with a rubber circle around it the exact size for them both to cover the area of a mercury battery (laterally), and a small tin ring on the negative side for better contact Sunny 16 kinda works, but not really: the lightmeter will read ok using sunny 16 on bright stuff like a metal door, but not so much on a stone wall right beside it, reading as 1 or 2 stops underexposedĭon't know if it's an uncalibrated lightmeter or if it's a characteristic of the lightmeter from the FT since it apparently captures the light from the middle of the frame To get to the right exposure at F11 I need to go to 1/30" (which is right) To get to the right exposure at 1/125" I need to go between F 2.8 and F 4 If I go one stop down either way (-1), the equivalent exposures should be Settings that should be equivalent are kinda weirdįor example, the lightmeter will go straight to the middle when shooting a scene at ![]() To compensate that I've set the ISO for 125 (I'm using an ISO 100 film) ![]() ![]() It's just 0.15V, and from what I've researched it makes basically no difference, maybe 1 or 2/3rds of a stop I'm using an LR44 battery (1.5V) because it normally uses a 1.35V mercury battery (discontinued, obviously). The only thing concerning me is the lightmeter. I haven't had it sent to be checked because the times sound/look alright, it loads the film properly, the camera itself looks like it came straight from the factoryĪlso I bought a Canon FL f1.4 II to go with it and I'm shooting a test roll I got a Canon FT, it appears to be working perfectly. ![]()
