Renata vs Energizer Batteries which is better?


Recommended Posts

I use nothing but Renata as I've yet to have one leak and ruin a watch.  Not that that means anything.  It just has not happened to me yet.  I have had however, several watches with Energizers and others, that have leaked in the watch.  It would be nice if some of you who are in the watch repair field could weigh in on this.    Personally, it's totally unacceptable for a watch battery to leak.

When the charge is exhausted, chemicals become acid and may corrode case and leak. I have never seen any battery manufactured promise in writing a protection for that.

Solution, do not leave discharged batteries in watches.

Yes, JDM, I totally agree, but the reality is people leave dead batteries in watches and some battery manufactures really do things on the cheap that make the problem way worse.  But yes, it's going to be a continuous problem.  The down side of batteries.  On a side note, I've had problems with AA and AAA batteries but since switching to Lithium the problem is gone.  The point is, I suspect the problem could be solved and yes, I'd be happy to pay twice or three times the price for such a quality battery.

For the most common sizes, Renata now offers a Premium type. Among the features they list:

State of the art leak proofness thanks to a new sophisticated sealing process

So I have to stand corrected about makers not making claims in this area.

To  put my 5 eggs in,  I use Renata, Sony and Maxell and have never had a problem. I recently had a Ladies Rotary that the battery had leaked in. A local franchised shoe repairer had forced the battery out and  lost the insulator,  then told the owner that it was BER !. I gave it the treatment and it left me OK. I do not know what the original battery make was. (All made in China I believe) He was probably OK with boots and shoes !!!.

they both leak, the problem is to leave the dead battery inside to long, or if the watch is not sealed and moisture manages to get inside the watch that would also cause the battery to leak

I've seen many brands of batteries leak. But the question is whether they were original or fakes?

I suspect that some repairers are sourcing for the best bargains online. If you take a look at AliExpress and Amazon, there are batteries that are ridiculously cheap. Once it is out of its packaging, it would be really difficult to tell its authenticity.

Searching on Google according to them Renata are the best. They are also the battery of choice fitted by premier Swiss watch houses including Tag HEUER, Breitling, Chopard and even Rolex for their quartz collections.

Renata are part of the Swatch Group so I assume would have a vested interest in quality required for watches.  I always use Renata and have had no problems with leakage.  Leakage problems encountered usually due to low quality batteries or not silver oxide type fitted. Similarly I would expect Seizaiken (Seiko) batteries would be ok.

Just FYI, we have a dedicated section here where is considered polite for new members to introduce themselves.

    • Nucejoe has made some good points about the calendar mechanism. If the watch physically stops at least the hands stop and the secondhand keeps going that means the watch train is running it means that it's a disconnect between the gear train and our minute hand in calendar mechanism. The Canon opinion which I'm going but I guess is the type that snaps into a drive wheel. The drive wheel is driven by the gear train the Canon pinion goes on the post there is no friction there. If the friction between the drive wheel in the Canon pinion disintegrates which he can then with the least amount of friction like a calendar mechanism it just quit striving. The hands come to a stop the watch keeps running the secondhand keeps moving because it's independence of all of this. It should have been obvious when the watch was going to gather and you check the setting mechanism before you put the calendar on you would have noticed zero friction as a guess. Even now when you go into hands setting you'll feel like there's no friction at all. Then the reason why the calendar mechanism works when you manually rotate the hands is because the setting wheel is driving the Canon pinion directly which is driving the calendar mechanism and that our wheel and all of that so all of that will run from that we just will not run from the gear train running the drive wheel that's connected to the Canon pinion. But that's just my wild guess and then we throw in Nucejoe's possible calendar mechanism increased friction than we need to really isolate all of this or we can continue to guess.  
    • I am not sure if I correctly understand you here. Only the seconds hand keeps running or minute and hour hands do move too, in case minute and hour hands move and show time right, then the fault is in date change train including date jumper mech, but if it doesn't show time correctly ( appear to loose time) then its loose canon pinion. You can tighten a loose canon pinion, use grease to lube it, not oil.
    • Thank you for your introduction and welcome to this friendly forum.
    • always confusing when it's two separate watches but I'm going to assume they're basically identical. What was their condition before you service them in other words did have a problem before and the problem came after you've serviced or was the problems there before? Then timing machine results you do have a timing machine don't you? In other words what's the running condition of the watch like of the watches barely running that would be an issue for a calendar change   then you fix the problem? so I'm guessing we only have to worry about the 2778 then? Yes this is what happens when you have multiple watches with too much going on it becomes confusing. then it would be helpful to have a picture of the dial side components because we didn't memorize every single calendar change mechanism. one of the places to look is the Canon pinion assembly in other words to visit have enough force to drive the calendar mechanism? I'm having to guess because I'm not finding a good tech sheet that shows the parts. If it's a kinda Canon pinion I think which is the Canon pinion that slips into her presses into with friction with the wheel if it no longer has and the friction then a cannot drive the calendar but if you manually set the watch that drives the Canon pinion directly and everything should function. then if you two of the parts list it would be listed as canon pinion with drive wheel. .But it would be helpful in the picture just to make sure http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&ETA_2778  
    • I think what the problem here is you're asking the wrong question. The question is what part number do I need so that I can end up with the correct balance? Or the correct balance staff for that matter? If you look at the second link it lists the parts for your watch. This is always where things get interesting? you'll notice for balance staff they list seven different ones. For balance complete they do show three but if you look at the part numbers there's only two. then I attached some images from bestfit online and of course additional problems perhaps. Notice you have lots of choices and probably only one that's right. then the physical bestfit book becomes interesting because is an indication that there are variations which is of course why there so many listed in the images. but fortunately it looks like you want the basic simple one which should be 100/66.  unfortunately for the third link it's out of stock. then providing this is the right staff number I snipped out a couple of more images of the bestfit book which is what the dimensions mean and the dimensions. One of the irritating things of the physical book is on the dimension chart if you're trying to find a particular staff you just have to be lucky to go through the list and find it it be really nice if they list of the sizes by the numeric staff also. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&AS_1287 http://cgi.julesborel.com/cgi-bin/matcgi2?ref=AS_1287 http://cgi.julesborel.com/cgi-bin/matcgi2?ref=U\ZD]J http://www.julesborel.com/s.nl/it.A/id.151223/.f
