replacement battery: Do I have to charge it before using it?

yes...in fact if you store a fully charge Li-Ion battery it will shorten the lifespan. If a Li-Ion battery is going to be stored or not used for several months at a time, it's best stored at about a 40% charge to help preserve the lifespan. but for just a month or two, storing at full charge should have no real impact on lifespan of the battery. A great resource for battery details can be found here: http://www.batteryuniversity.com/ If you are going to buy a back-up battery or two, put them on a rotation (it helps to number them and cycle in sequence, I also date them as most Li-Ion batteries have a reasonable lifespan of about 2-3yrs before you begin to see the inability to hold a charge anymore). I have devices where I use a 4-5 battery rotation. For my DSLR's that way each battery gets used and recharged when the power level drops to about 30%-50%. I have a K1 and never bought a backup battery because I decided to just want and see. Now after about 16-months I do need a new battery. I find I pretty much only need one battery for the way I use my reader. Though having two would not be a bad idea is one develops issues so you are not without use of the device while waiting for a replacement/exchange. I am on the fence if I am going with a non-OEM battery or the OEM genuine battery this time around. If I do buy a 2nd battery, I will do the rotation thing every month or so.

You can charge it with the USB connection for its original AAA rechargable battery. Of course, you can charge or replace the battery at your convenience.

I can't answer that. The battery is charged prior to use. Perhaps you could contact manufacturer.

You put the battery on the phone and charge it right away, as soon as you receive it from Amazon, if it has no charge. I the battery has charge, then you use it until it does not have anymore charge. There are no instructions when you receive those batteries from the vendor. You just follow your best judgement. You don't ruin the phone nor the batteries if you use them right away.

Yes, sort of. These batteries have specific eflite-only plugs, so it's necessary to either use their charger or to get an adapter that goes from the battery plug to the charger. If you have that, then charge away!

I too leave mine plugged in. However, when I have left it out for a little while, always charges right back up. I don't see how the battery can be replaced. I have had mine several years now and cannot complain at all about how it works.

Yes, just plug it up to charge before use and it will last for quite awhile before it needs to be charged again.

I have had no need to replace the battery. I normally leave the unit on charge overnight. A side comment is it is worth the money.

Could not find anything in any documentation that came with the battery. However, my experience is that the battery operates slightly over 2 hours before it needs re-charging.

The battery arrived somewhat charged but you do need to charge it for a full battery.

Yes, the battery needs to be charged before use. Select a charger that is rated to work with NiMh batteries and follow the manufacturer instructions.

The battery is built in, so you don't replace it. It has a USB connector, not unlike your cell phone, which you charge it either via your laptop or with the cord and plug that comes with the unit.

No. I think you have to order the charger separate. I only needed the battery so I did not check further.

Charge it for 12 to 24 first, then use it as normal. You probably don't have to do that but I always do to be safe.

No, I just charge it after I use it and let it sit until I use it again. Seems to work for me.

Yes, make sure to follow the instructions on charging the battery or it will need to be replaced. �
