Do I need to charge the battery before installing or does it come ready to use?

The battery is sufficiently charged when installed. When you start the car, the battery should charge normally. I have had no problems with the battery.

It comes totally charged. I have a computerized charger which l connected, not knowing, and it read 13.3 volts "charged" right out of the box.

My battery came with a charge. However. I would recommend charging the battery to capacity before use. This battery doesn't have memory problems that will cause your power to decrease over time, so you don't have to charge too capacity before first use.

Yes you have to charge it for about an hour or until battery shows fully charged.

I didn't have to charge the one I got. After initial testing to ensure it worked, I did put the Battery Tender on it and it has remained fully charged.

No, the battery came fully charged and ready to use! If yours is not fully charged, battery came with great instructions on how to use. Super easy!!

When new it comes already charged. When charging you don't need to turn it on.

A good question; however there is no definitive answer since there are so many variables. Myself, I always put a new battery on trickle charge before installing it. I use this particular battery for my security gate. They both showed acceptable levels when they arrived; however once under a load it becomes a different matter; thus the trickle charge fully charge them. Just my way to make sure the battery is fully charged before I install them.

I checked with my daughter, since I bought it for her laptop and she's the one who installed it. She did not get that message, but did mention that the battery needs to be charged before it will work. I don't imagine it would charge, though, if it's "not detected", but maybe you could leave it on for a while and see. You can probably tell I'm not very "techy". We didn't know until after we bought the battery that the laptop would work perfectly well just plugged in, with the battery uninstalled. If I'd known that, I probably wouldn't have bought the battery at all. Sorry I can't be more help. I checked with my daughter, since I bought it for her laptop and she's the one who installed it.

There's no way of charging it before you install it. It has to be in the laptop in order to charge it.

I had the power cord arrive with product. You definitely need that in order to charge the battery.

The battery was dead when i got it. It recommends u charge it before using it. I never had any problems with it. Once i charged it initially it was fine.

it comes with a very small charge. You need to charge first before you can use it correctly.

No need to charge the battery first if you have it plugged in. There is a form without the battery, in fact.

It is at least partly charged when it arrives. There is nothing for you to do, because it automatically charges once you install it.

This model comes with built in batteries and a charger. You need to charge it before your first use.
