How many hours for the first time charge? Is it wise to recharge before it is completely empty or should be completely empy before recharging?

ask a tech person.
i was always told to let it empty completely and then charge until full.
charge overnight
lithium batteries do not “memorize”
I would charge by the specs in the instruction manual.
My docking station has lights to tell me when I am charged. I never timed it.
It comes from the manufacutrer with about a half charge….Do not leave it discharged for any length of time….
Good luck
16 hours the first time
charge whenever you want
they last longer, the longer you have them
All the Li-ion chargers I have ever used shut off once the battery is fully charged.
I recharge mine just before going on a shoot so I have no worries. In addition, I take one of portable (runs off the mains and the 12v system in my SUV) just in case.
My DSLR uses one battery at a time, so when one gets to zero charge, I can pull it and use the remaining battery while the first one recharges.
I have three digital cameras , It takes about two hr. to recharge two of them . The other is a video cam. ,It takes AAs
I like to wait till they go dead then recharge them but ,I do recharge at 1/2 if I plan to use it for the day.
Only your user manual can give you the correct answer. I suggest you read it.
btw…you do not need to completely discharge a lithium-ion battery before recharging.
When rechargeables were nickel cadmium batteries, it was crucial that they be recharged only after they’re dead. That now is no longer an issue especially with nickel metal hydride (NIMH) and with lithium ion batteries.
You can top up lithium ion batteries, you can also run them to almost dead before rechargnig, either way you can’t hurt them. What’s also nice is that lithium ion doesn’t lose charge the way the NIMH batteries do, so once you’ve charged them they tend to hold their charge for quite some time and a lot longer than the others.
How long it takes to charge them up depends on the capacity of the battery and the chargnig rate. So it’s impossible to tell you how long yours will take, your owner’s manual should be able to tell you that. Usually though charging them varies from and hour to three hours with most brands and capacities.
You should charge them initialy when you get them but there is no special time needed, just charge them according to the instructions provided.
Yes it is wise to recharge a battery before it’s completely dead. But you don’t need to worry about that. Once your camera says it can no longer work with the battery, that’s dead enough to recharge. I’d not go beyond that point because you may in that case damage the battery. Rechargnig before it’s “dead” doesn’t hurt it at all and is something you may want to do anyway. If you’re going out to take a lot of pictures it’s always a good idea to top up the battery before you go.
I hope this helps a little.
