Battery question?

[markyd3]

Could someone tell me the difference between 303 (SR44SW) and 357 (SR44W) batteries?

I assume theyre the same size so which should I go for??? Im confused lol

[clockace]

they are the same size. one is rated high drain, the other low drain. i forget which is which, but they seem to be sold now as a combo 357/303, so it wouldn't make any difference which you used. i don't think that is the size for the bulova driver however. i have one and i think the cell # is 328 [or 329] it should say on the watch back what cell to use. peter

Hiya,

I was just going on the info given on this site lol

http://www.crazywatches.pl/bulova-compu ... 6-led-1976

Although this site also seems to suggest that the Bulova drivers watch i have bought will have an N7 module ie one button where as these pics of mine suggest to me it has 2 buttons and will therefore be an N6 module!!

Although the 303 & 357 are the same thickness and diameter normally the (older) 303 cell has a "nipple top" on the megative pole while the 357 has a flat top. Trying to fit a 357 in a watch designed for a 303 can be frustrating- either the cell doesn't make contact or shorts out (especially in badly soldered Hughes modules!). In reality the actual high/low current difference is hard to see nowadays. Exception- Seiko (Hitachi Maxell) 357s have a nipple top!- best of both Worlds as you get high current with maximum clearance.

N7 and N6 are not module codes- they are date codes, N is the decade, 1970s, 6 & 7 are the years in the decade- on Bulova watches. So 1977 & 1976 manufacture. The seller you bought that watch off is a pr*ck of the first order. Funny how (s)he has batteries to go in every working watch (s)he sells but none "the right size" for the broken ones.

Hopefully a bit of visual humor will lighten the situation a little.

LOL maybe a little

I'm thinking the 357s work just fine in a Bulova driver...only ones I've ever used in them.
