To obtain the best battery life over time...Is it best to discharge the battery before charging or is it best to give the new battery a full charge?

The battery comes partially charged. It is best to fully charge the battery before using it. Once fully charged, unplug the battery from the charger and use the laptop on battery power only. Do not let the battery fully drain, but rather charge the battery to full once it is down to 15-20%. Do this for a few cycles and your battery will be properly conditioned.

Fully discharging a battery is hard on Li-ion batteries. You should try to not let it go below 20%, though having it plugged in all the time also isn't good for it. Newer laptops have a mode that will keep the battery around 80% charged if you have it plugged in all the time.

The directions I got with the last battery I purchased on Amazon is to charge for 18 hours, then run it down to 8% for the first five cycles. Hope this helps

You might want to Google this one. But understand you need to charge the battery All the way and let it discharge almost All the way for the first couple of charges.

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 recharge mine every night. Lithium-ion batteries do not need a full discharge and recharge to maintain its battery life. Whether you discharge it 25%, 50% or 75% before charging it doesn't effect the life of the battery. I've had this battery for a year of constant use and it still works awesome.Overcharging or discharging too low is bad for the battery but most phones stop charging or shutoff before this is an issue.

No battery is fully charged, unless you buy it at a store, have them charge it overnight and pick it up the next day. This battery is a good one for the money in my opinion and should last a long time, but time will tell as I have only had it five months. And No it was not fully charged and I would say it was so discharged on arrival that waiting to recharge it much longer may have already shortened its life. Buy a CTek 3300 battery charger they are the best and has made some of my batteries I have last 10 years.

I always recommend following charging instructions. The battery may appear fully charged, but almost always isn't.

Battery life really just depends on how much you use it.You can prolong the life of your battery by not letting it sit dead for a long amount of time, and not leaving it plugged in after the battery charges to 100%I don't think the life is too shabby, but definitely not breaking any records if you are using it heavily.

I believe, I charged this new battery for approximately 8 hours before the first use. Now, it takes, perhaps 1-3 hours to fully charge. It's been a good battery...much better than the OEM.

In my opinion I would say . Recharging while still half charged will indeed shorten the batter life. It will be over a period of time. It will be hard to say how fast. Best ans. use till quits & carry a spare

Yes, it's best to fully charge & fully discharge several times of first use

Most likely you have to charge the new battery first before you can use it. These type of rechargeable slowly discharge themselves even if it is not used. The fully charged battery usually depletes in several months. The new battery may or may not have some charge left, depending how long it has been on the shelf. Also, it is recommended to fully charge the new battery before the first use.

Store your batteries fully charged. Also, try to avoid letting lithium ion batteries (like the ones in cell phones) discharge completely after the initial 4-5 cycle "break in" period.. Repeatedly draining them all the way can shorten battery life. Most battery chargers have a protection circuit built in so leaving a battery in the charger past the time it is fully charged will not harm it.

Most Li-ion battery manufacturers recommend that you charge fully, remove from charger as soon as possible after battery is charged and don't let them run down completely. I usually re-charge mine when they are about 30 percent remaining. I keep a spare battery and rotate them whenever I can. Manufacturers also don't recommend storing a fully charged battery for extended periods. That's why I rotate mine. I have never heard a reason for not storing a fully charged battery - maybe someone else has the answer to that.

No, it comes with the rechargeable battery installed already. Just charge it over night before the first use. My wife used it til the battery was completely run down for the first few charge cycles. That helps the battery last a lot longer. After that you just keep it in the storage/charge stand and it will always have a full charge.

BEFORE USE, let it charge all the way to get maximum efficiency. I charged mine for 8 hours to get a full charge. One must be patient to reap the rewards.

None of these answers look right to me.. From the manual: "It takes at least 24 hours to fully charge the battery". From the quick start guide: "Before you start, charge for 2 hours minimum". Basically: 24 hours for a full charge. If you can't wait to use it, make sure you charge for 2 hours before using it the first time.

I had issues with my battery because I kept it charged when not in use. I found out you should NOT keep it charged; rather keep it in the vac until it dies and then recharge, this will extend the life of the battery. I bought a new battery and that solved my problem. Good luck.
