Powertron (10) CR2430 Lithium Watch Batteries Battery

Batteries arrived exactly as pictured. Installed one as a backup in a clock-radio and unplugged it for a few hours. Plugged it back in and date/time data was retained. No idea about longevity in use or shelf life of the batteries. Only time will tell.

These batteries are the worst crap you can get. Unfortunately one often cannot tell how bad they are until you have install them and weeks later only to realize there is hardly any charge in them. Fly by night brands and counterfeit name brands are abundant here, so choose your poison. There is 1/100 amount of charge in these battery so kiss your money goodbye and wear out your equipment needlessly. In my case is a Suunto watch. Why don't I buy name brand battery, you ask? Because I have been cheated with counterfeits so I thought I would give the no name brand a try, as there is no motivation to counterfeit them. Do not waste your money.These batteries are crap. May be I should take one apart to share what I find.

The batteries came with a good charge and were really reasonable compared to other sources. I only needed one battery but the price was right. Hopefully the extras will hold their charge for a very long time as it does not seem that the replacement is going to run out of charge any time soon (or I can find some other uses for the extra batteries?).

They were ok for the price. 1/3 of these batteries did not last more then 2 months so I guess you get what you paid for. Probably will buy name brand next time.

bought as replacements for an electronic dog collar, seem to do the job and the price is good

The batteries work fine.

BATTTERY OK

If you have a sabin tuner that sticks to the body of your guitar these batteries work for the sabin tuner way cool at bargin price I give a few to help others.
