Same here, but with AG10 type (or similar). Are there any good blister or brand? I've found them veeeery cheap online. The only thing: here in Spain, in chinese shops, you can buy one for about 0.60-1 Euro, but... they all suck |( I've bought once a batt/cell for my Casio wrist watch. Darn, I pushed "Light" button and the screen goes off, then, when backlight turned off, the screen lit up again showing the clock. The batt lasted 1 month |(
Since then, I buy quality cell/batts @watchrepair shops and such. From 2 to 3 Euros, but the lasts exactly what they should.
On inet I've seen blisters (x10) for 2-4 bucks, that's .2-.4 per cell :O And with shipping. Great price, but if they last 3 to 4 time less, I think I'd prefer to buy one for 2 Euros :| (intead of changing them every 4-6 months).
I bought some various cheap ones at ebay for computer uese (motherboard bios settings retaining battery) and thsoe have yet to fail me. Soem are in clocks, some in scales. All work well for over 1 year. Probably those will still do a few years.
I just wish DigiKey, Mouser, Farnell and the like didn't have such high shipping costs to Israel (30$-40$!!). And I wish there was a decent electronics shop here, everyone overcharges as if they sell gold - simple 1/4W resistors cost at least 1$ each, transistors that sell for 1$ on eBay cost 10$, and "hard to find" parts (that is, available on DigiKey for 2$) require "special order" and can cost many tens of dollars.
