Battery charger options

[RobNYC]

So the battery for my Quando II says

Phylion Battery
Hi-Energy Battery
XH370-10J
DC37.0 V

Anything you can share with me about this battery?

[flecc]

I can't be certain from that Rob, but can you tell me the date when you bought the battery?

I assume you got it from Nycewheels.

yup.... nycewheels... got it April 1, 2008. wondering if i should call them up and ask them for more info about it but not sure what to ask.

Since only small stocks are held to avoid deterioration in storage, that will be at least the later 10 Ah Li-ion made by Phylion which is very much better than the earlier ones from mid 2007 and before. I think the new Sanyo made one will be superior, but it's too early to tell exactly how long each of these types last.

The improvements in the chemistry are continuous as soon as they become available and are proved. A bit like computers and digital cameras, when you buy one it's out of date by the time you've unpacked it! That's probably why the model labels only indicate the construction rather than the chemistry, the latter codes being marked on the cells.

If you can tell me the serial number with prefix below that model number, it has an alphabetical prefix and a very long number beginning with 1, I will be able to tell you more though.

Flecc,

That dog of a battery that came with the bike dates back to 2006..... in your opinion do you think it's good practice to ship a bike with a battery that has been sitting on a shelf for, possibly, more than two years?

It's pretty much by the by now anyway as Ezee have sent me a free replacement Phylion (along with the Sanyo) which was made this year but it still pees me off when I think that a certain outfit knowingly sent me a lemon and was quite happy to take my money..........

That's three batteries I have now.... 1 lemon and two good 'uns.... would you rotate them or would you tend to use one of them till it's as flat as a pancake and store the others for a rainy day? If storing I assume you would keep the stored ones in a fully charged state?

[flecc]

It's never worth storing Li-ions, since they constantly age whether used or not, and I'm not surprised that 2006 battery was dud at receipt.

In your position now I'd write off the lemon and just use the two good ones to enjoy their fullest performance from new.

Thanks, Flecc. If you ever make it to NYC, you are welcome to tool around town on my Quando II.

Hi Rob. That was from a Phylion manufactured batch supplied from eZee around January this year, but the date of manufacture may be a bit earlier, and should perform quite well, though as said, not up to to standard of the latest but more expensive Sanyo one.

One member has another from that same batch, theirs is 10057, (New edit inserted). I've just heard today that their 10057 is playing up, so it's not certain how yours will last.

I've found them extremely variable even when from the same batch. My original two were sister batteries from the same batch, one very quickly failed, while the other went on to three times it's life, still not very long though. Personally I'm relieved the new generation batteries like the Sanyo are so good now.

Thanks for the Quando ride offer, but I'm unlikely to get over there any time. I keep telling my sister who lives over there that she has to visit me!

Have just been catching up on the forums after not visiting for 6 months, and was just about to start trying to source a NiMH replacement for my early 2007 Torq. But Flecc has managed to convince me to to stick with Li. So does anyone know where can I get a Sanyo Li pack for the Torq (ideally without having to wait)? I am in the UK, but don't care where it ships from.

What does "playing up" mean?
