should i let these batteries completely discharge before i recharge them? i've never used rechargeable batteries before.

No, you can "top up" these batteries from any level of discharge. Try to avoid letting them discharge completely before recharging (may reduce lifespan), and let them cool before charging if they are hot.

That is not necessary. Only Ni-Cad had the memory issues that required periodic full discharge.

I have used these since March, and have re-charged them countless times (I use them to power a baby swing). I re-charge them when the swing stops working, but not totally dead. I don't think it's necessary. I try to "slow charge" them as much as possible (which the manufacturer of the Maha machine says saves battery life.) Hope this helps.

I don' know. I believe letting/not letting them discharge is NOT an issue with this type (they don't have the ghost charge problems other models do) . I recharge mine when they still have life left and haven't noticed a shortened lifespan, but haven't done a formal experiment.

To be honest I did not discharge them first. I put them in the bays that worked. I had problems with a few of them. I now just tried the bays that did not work worked, but with a different kind of battery. There is something wrong with mine. Bummer

My under standing has alway been to fully charge them before use and then run them down to like 5 percent before fully charging again. I think you are supposed to do this the first few charges. I have never really found that this makes a difference. Just keep I mind you won't get full battery life until your batteries have gone though a few charge cycles.

Ken,I did not think these were rechargeable. I have never tried to recharge them.Dan

Thanks Phil. I was concerned that these batteries that are factory pre charged have not been on the shelf for months. There is a limit to shelf life on these batteries.

They do come with a charge but not fully. You should charge them completely before using.

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

I leave them on the charger. I bought the batteries in a set that came with a charger and the charger I have auto shuts off once the charging is done. These type of batteries are also designed to not lose their charge over time as many other batteries do. So I would say that you can leave them in the charger.

hi, always rinse them off with water immediately when done swimming and never let the battery go below a 1/4 charge. Even when storing and not using for a while, you will want to make sure to keep the battery charged. Also, they don't last for ever and if you have a local battery dealer, they can make a custom battery for you that will last longer then the factory. This is just my experience with the unit. I hope you find it useful. Tim

They are charged some, but no batteries stay in there charged state indefinitely. There is always some discharge, so you will be well advised to charge then upon receipt of them.

These batteries can be recharged repeatedly whether they are partially or completely discharged. Perhaps when they have been used repeatedly over a long period of time, it would then be useful to give them a complete discharge and refresh.

We leave them on a little while longer without noticing any harm - and nothing in the packaging of any charger I've had suggests you have to get the batteries off immediately. I wouldn't store my batteries there :) But all that happens is the light for the charged battery goes solid and the others continue charging if needed.

it's always best to charge any battery at first use. I have trouble with my charge light also. The flashlight work great for the first few months, now it doesn't seem to hold a charge for very long at all.

The batteries were put in my flashlight and used a little. I then took them out and put them in the charger and they charged right back up!!! I love these batteries!

Keep the extra batteries clean, dry and fully charged. Also, rotate the batteries for use. Why have three if you only use one. Not sure if not using them causes issues, but it can not hurt to rotate their use. Best of luck. Alan

To have them recharged, you must insert batteries in pairs and use all 4 positions. Try it and let me know if it works, there is too much time I don't use mine, so that I am not sure about it, but I remember I have had the same doubt.

I recharge mine and they seem to work fine. I usually only recharge them 2 or 3 times then I toss them.
