How important is it that these get charged together in pairs? I ask because not all of my stuff uses an even number of batteries.

It depends on your charger not the batteries. As long as you realize which ones are charged, it doesn't seem to matter. My son uses them in his r/c vehicles which use various amounts of batteries.

Glad I was able to help. If you are not sure what charger you would like to have, I can tell you that this is the one that I have been using for over a year now and it works fine for around $40.00La Crosse Technology BC-700 Alpha Power Battery Charger

It depends on your "charger" not on the battery. The charger that I use allows me to charge one or up four batteries at a time.

There are chargers that will do any number, most of them are smart chargers but you can get the Panasonic Advanced Individual Cell Battery Charger with eneloop AA 2100 Cycle Rechargeable Batteries (White, Pack of 4) charger which is a pretty good buy. I highly recommend you get one with an individual charger as when you charge them in pairs one battery might have more charge than the other and would undercharge the other battery. Plus it would be ideal for you since you need an odd number of batteries.

Yes, I use recharged batteries all the time. Just as long as they are the right size. Do not mix the types. Use two recharged or two that are new.

You can charge two batteries at one time. The picture is very misleading. The picture appears that the four batteries are actually connected to the charger but what you are seeing in the picture are the four batteries touching the side of the battery charger.

When you connect them like this, they operating in parallel - same as if you had wired the batteries in parallel yourself. Each battery will receive the same charging voltage. For some batteries, this this will be the correct charging voltage, However, the other batteries could be over-charged or under-charged. All the Battery Tender sees is one battery!This is answered on the Battery Tender website. The explanations are excellent, with clear diagrams. Find this info in the education section - it's a on pull-down tab, at the top of the homepage. A good reference for all battery charging and connection questions.

Don't think it really matters because in balanced charge mode (I use every time) when one cell reaches 4.20 it will keep charging the others till they hit 4.2... But you must use matching battery's... Same mAh and cell count.... So if you have 'two' 2cell 5000mAh battery's you would charge them at 5.0v coz there both 5000mAh and you would have 4cells in total so choose 4cells on ya charger.. Hope this helps...

Can you clarify. Are you asking if there is a case (to hold these cases) that anyone knows about? If so, I haven't looked into it. I just store these in my file drawer. My main purpose is to keep the sets of matching batteries together and also to have them stored so that they don't contact each other while being stored. But each of the 9 cases links together to form one big "chain" case if that's useful.

Could not find any information stating to charge in pairs only. My charger has room for 8 batteries but I only charge 6 at once with no issues. The charger does get warm but it never had any issues.

Those batteries need to be recharged in pair. I guess that is the reason Sanyo paired batteries in different color in this set. It helps when you only use 2 batteris at one time, easy to tell which pair needs to be recharged. Other than that, batteries self are no difference. I bought the batteries only set, and they are all white.

These are facile batteries and charging is difficult to pin down. The first time I charged them it was maybe about and hour, but they were not completely drained either.They should not be over charged are over used in my experience. They get really warm in the torches and will at this point discharge rather fast. I try and watch them when charging because I really don't trust them, when the Green light comes on I take them off the charger quickly, hope this helps.. PS: this is the first time I have had all eight being in perfect working order since I started using them.

It depends a little on your charger. Many chargers charge two cells (batteries) at the same time by putting them in series. That means they are both being charged at the same rate and are stopping at the same time. With this kind of charger, one should keep a pair of cells together for their whole life. If your charger has room for two pairs, the second pair can be different. If your charger has separate lights for each cell, then each cell can be different.

Just put them in the charger, side by side. Batteries must be charged in pairs, either two or four at a time, and they must be of the same type. If they are not charging, one of them may be bad. Try switching one of them to find and get rid of the bad one.

The smaller battery pack probably will not last that long. Maybe if you charge one pack while using the other. They sell a larger 5-cell pack that might go that long. I have never used mine continuously like that, but they do hold up for a good long time.

Depends on how much you're load is. Two battery s will stay charged no problem if you are not loading and charging at same time. However, once batterys are discharge it will take a half day or so to recharge. If you want a consistent load you will need to get an extra panel or two to do both at same time I have been happy with the bundle so far. I can run a 60 tv or floresant light for 6hr or so off of 1 reg bat.

I have no issues , I love these and have 4 sets so I always have a charged set , and with 4 out of 4 working perfectly thats about as good as it gets.

I can only answer as a mechanic; one battery is always charging while I'm using the other. As one battery starts running down I switch them. So I alway have a spare.

you can charge them as much as you want they don't acquire a 'memory' but as soon as the fully charged light comes on remove from charger they can be damaged by being left on charge they don't seem to discharge just lying around the mah hours on these batteries are greatly overstated

I usually charge them overnight so I don't have an exact time to "full charge".You may have one or more wornout batteries.
