If these batteries won't be used until later (until travelling overseas), is it best to leave them as shipped or charge them initially?

I charged them as soon as I received them just to make sure that they worked as expected. If you waited until 30 days later, you would not be able to return them if found to be defective.

I have had one charged and waiting to be used for a couple months and it's still fully charged so I would charge them in case there is a problem with power conversion overseas.

Charge the batteries right away. If there is a problem then you can return them. If all is good, then maybe just check the day before you leave to see if they need a charge so you are able to take pics right away.

Best to charge before going overseas, but might need te recharge when arrived at destination.

Do not drain them. Charge overnight BEFORE you use them. I know in the past to drain then charge, but not with these.

In my experience, if you put them away fully charged, I came back over a month later and they still had a full charge. I always leave the charging battery in the charger for a few extra hours after the charged LED turns green. Seems to work well for me...

yes i do believe that is correct.. one thing on the batteries always make sure to run them down and recharge fully before use.. don't leave batter in charge after its done charging, after about 5 or so cycles you will notice the power go up and use time extend as well..

I have received two separate orders and the batteries are all fine. I have been using them in my Camera for quite a while. the first time I charged them they took about 24 hrs but since then overnight seems to be all they need. I am afraid that is all I know about them.

They had a charge, Lion batteries should never be left discharged. I always charge and discharge several times after initial use.

Hi Gregory! I just asked the question of the best "proven" way to charge these batts and I'm convinced by the majority of answers is to use the USB end and keep the mAh's the same 1 thru 5, of course. It will take longer, but successful all around, as many have said and I tend to agree. Some have used, me included, a 3.7V wall charger, but I don't feel any longer. I hope that this helps and puts your mind at ease as it does mine!&#128522;

I used to work for a battery company. If you keep them charged you should get 3-5 years out of them. Store them in your basement or somewhere cool. Do not freeze them ever

I would charge it for a full 15 hours before using it. They usually come partially charged, so doing a full charge is the best way to be sure.

Yes. Batteries are shipped with only a partial charge. It will be necessary to give them a complete charge before use.

These batteries do not have a "memory" so they can be charged at any time. They do not need to be completely discharged before recharging.

It would be best to. I have always liked to fully charge my batteries before I use them for the first time.

these batteries take some time to charge. It is the nature of the beast that the time extends as the charge reaches higher capacity. The last 10% can take as long as the first 70%. I find the percentage on any battery as more of a guideline than a definitive measure. I wouldn't say you have a problem with the product just yet.

I always kept mine fully charge and in my purse for backup. The batteries will be fine, I used mine for a year like this until I got a new phone. The batteries are still in great condition. The true worry comes from leaving them on the charger to long it cause the battery to get hot and expand which makes them go bad much faster.

This is my first time ordering a large quantity of batteries (April, 2013) but from reading the other reviews it sounds like a win/win situation, I've even learned about putting them in the refrigerator. I mainly use the rechargeable but the disposablesare convenient for travelling. The exp. date on the batteries is May, 2016.

You should always allow a Lithium Ion battery to fully charge before use. Overnight is best.

My battery had a minimal charge when I RECEIVED it.I believe we are expected to fully charge it before using.
