Sanyo XX 2500mAh NiMH batteries experiences and results

I have 4 Sanyo XX batteries as well as 4 Sanyo 2700 batteries.
Results so far with my XX batteries:

XX1:2474;2595(tested with BC-700);2377;2452;2339;2369;2384;2447;2247(charged with 30min-charger);2361
XX2:2491;2575(tested with BC-700);2361;2516;2395;2431;2349;2501;2268(charged with 30min-charger);2423
XX3:2491;2375;2416;2443;23390;2434;2394;2444;2242(charged with 30min-charger);2355
XX4:2480;2530(tested with BC-700);2368;2464;2350;2404;2383;2467;2270(charged with 30min-charger);2388

I then charged all batteries again and left XX4 for 3 weeks in storage. It had 2159mAh left.
XX1 to 3 are still waiting. I will test XX3 next month, XX2 2 months later and XX1 in about 6 months.
It seems they perform very good! Discharging in the BC-700 gives about 4 to 7% better results. Charging in a 30min charger does not fully charge.

Results with Sanyo 2700 batteries:
S1:2552;2680(tested with BC-700);2495;2532;2516;2470;2483;2584;2249;2493(charged with 30min-charger);2493
S2:2564;2485;2540;2566;2481;2464;2465;2559;2283(charged with 30min-charger);2487
S3:2597;2502;2471;2520;2492;2493;2501;2564;2258(charged with 30min-charger);2468
S4:2580;2528;2497;2498;2471;2534;2503;2569;2277(charged with 30min-charger);2490

S4 after 3 weeks of storage still had 2269mAh left.
Charging XX and 2700 in my 30-min charger gives my the same results for XX as 2700.

Firstly I did a break-in after discharging the new batteries. XX's had about 1000mAh fresh out of the pack, the 2700's about 350mAh.
Sanyo 2700's gives you about 100mAh extra compared to XX's, this still is true after 3 weeks of storage.
Charging has been done in either the MAHA C-9000 (at 0.5 to 1C) or in the Lacrosse BC-700 (at 0.3C). Since I believe the MAHA C-9000 does not always fully charge. It stops charging at 1.48V instead of at the -dV point, I continued charging until termination in the BC-700.

Results from my first tests using the C9000 back in December:

500 mA discharge fresh out of the box:

954 mAh
961 mAh
962 mAh
957 mAh

Break-in (set to 2500 mAh):

2412 mAh
2411 mAh
2405 mAh
2433 mAh

Sanyo Eneloop XX

Hello

Was any good information on these batteries available before the CPF crash that someone can re-post ? I would like to know if the extra 400-500 Mah will make my zebralight h51f, and fenix l2d flashlights brighter ?

I just purchased a pack, they most likely will not be here for a weak yet.

Re: Sanyo Eneloop XX

mAh denotes the capacity (milliampere-hours), so the XX Eneloops will last longer between charges, but no, they won't make your light brighter.

I was looking at these, but they are only rated for 500 recharge cycles instead of 1000 or 1500 for the standard ones. Now I know that's still once a week for ten years, but I still wonder if it's a reasonable tradeoff.

Perhaps better to move this to the batteries subforum.

Re: Sanyo Eneloop XX

Wrong forum. Moving to Batteries...

Re: Sanyo Eneloop XX

I have read that the Sanyo's eneloops are the best but I would like more tests done.

Re: Sanyo Eneloop XX

The test information we have shows that the XX Eneloops can maintain almost the same voltage under load as the regular Eneloops. This is remarkable for a high capacity battery. However, you do not get something for nothing, and the probability is that the XX batteries will have a shorter service life than ordinary Eneloops. With the XX you get good high power performance and a 25% longer run time between charges in return for a substantially higher cost. You have to decide if that is worth it to you.

Where did you purchase your eneloop XX's? Can't seem to find these in USA from a reliable source.

You need to buy them from a vendor in Europe and have them shipped over. They are not yet being imported to the US.

Re: Sanyo Eneloop XX

Any idea why this is only available in Europe and whether there are any plan to release to rest of the world.
Thanks

They are not available in the US because they are X rated ! May be if you explain that they are BATTERIES ?

Re: Sanyo Eneloop XX

Just last night I picked up (4) at canada computers here in Ontario, Canada....they just received there shipment from Europe!
Now if my SC51 ever shows up to try them in.......

For you Canadians out there, Canada computers have them in stock! I just bought (4) last night here in Hamilton, Ontario for $22.99 + tax.

Here is the direct link 'http://canadacomputers.com/product_info.php?cPath=2_746&item_id=036102' , oh if I'm not suppose to post direct links, please forgive me and can someone advise?

Not sure if they ship to the US though?

The main reason for not posting direct links like that one is that they expire. Next year someone may click on it and it may not be valid anymore. It's probably sufficient just to give a detailed pointer to the vendor and the product code. Anyone with a browser will find it.

Thank you Mr. Happy for the clarification, your right as a previous bookmark I had on that site did not work after they overhauled there website.
I was more concerned with breaking any CPF rules on posting?

There is a set of posting rules found on the forum home page, but just use common sense. If it feels wrong, it probably is wrong. A moderator will let you know if you cross any boundaries.

Another website for Canadians would be Xpress Canada.
They sell the 4 pack at $17.00 + shipping/taxes. Got mine at $24.14 ALL included.

Hey thanks Nightime, never heard of them before....better price and shipped from an hours drive from me!

We want these XXeloops in the U.S.A !




Canadians have all the luck . . . .

Round Bacon, and now these SuperXX Eneloops !

My LSD test continues.
Now I discharged a Sanyo XX and a Sanyo 2700 after storing them for 2months (60 days).
XX: 2130 mAh
2700: 2180 mAh
Different XX and 2700 had 2159 and 2269 respectively after 21 days of storage.
I guess they will have the same capacity left after 3 to 4 months.
So if you will not store batteries more then 2 (probably to 3-4 months) the best choice is Sanyo 2700's.
I will do my next discharge test 2 to 4 months from now. So after 4 to 6 months of storage.
Might be 4 months for cells number 3 and then a discharge of the cells number 4 after 6 months.
