Is there a best brand of the coin and button cells to run the hp calculators? Thanks on advance for opinions.
I don't use any other than Eveready Energizer. They have a patented process for low leakage. you can store these batteries on the shelf for 10 years. Try that with cheap imported batteries.
Thanks Paul, I have used Energizer batteries for the most part, just seeing if there anything I was missing.
I got a bunch of LR44's from a Chinese site, at about $1 the dozen, and some of them started leaking quite a long time before reaching the expiration date...
