The BLF Battery Data Base

Some Pisen AAA's arrived a short while ago , also some 18650's [ Sanyo - Samsung ]

http://www.dealextreme.com/p/pisen-hr11-45-1-2v-800mah-ni-mh-rechargeable-aaa-batteries-2-pack-18316

Well , look nothing like the picture .. 800mAh capacity claim , Pre charged claim , and low self discharge claim , Since its in Chinese ???

Will discharge first , then charge and re-discharge from being fully charged .

Out of the Packet : Discharged @ 500mAh

1/ 680mAh

2/ 688mAh

Ok charged them up , and then discharged again at 0.5A

1/ 793mAh

2/ 804mAh

Those are pretty decent numbers but who knows how they'll hold up over time.

Just got this one in , Sanyo 2600mAh capacity .. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=370406814898&ssPageName=STRK:MEWNX:IT#ht_2220wt_905

Discharged at 0.5A to 3v .. Now some manufacturers say you can discharge to 2.75 or 2.5 Volts under load ..

Anyhow , the hobby charger stops at 3v under load = 2433mAh to 3v ..

Being Sanyo there is no protection circuit ..

Discharge Termination Voltage: 2.75V

Capacity: 2800mAh (Min 2750mAh)

Well , after charging to 4.2v , and then discharging to 3v under load [ 0.5A ] I got some 2486mAh ...

If I were able to discharge lower it may have come close [ may have ] to the claimed minimum .

So keep in mind that discharge is between 4.2v and 3v ..

Thanks again for all the work you're doing collecting data on these batteries, Old4570!

Unfortunately more Junk ...

Discharged as arrived = 0 capacity

Charge @ 0.5A then discharged @ 0.5A

= 1st cell was 251mAh / 2nd cell was 263mAh , which is really poor capacity ...

Pic in the bestinone thread.

Claimed capacity 600mAh - first one tested gave 568mAh on a Turnigy Accucell 6 at 500mA discharge rate. Semi-button top.

Hold output on a demanding AA (It does have an XM-L in it) light better than a flame Trustfire - both freshly charged, the IMR on its first cycle, the Trustfire with less than 5 charges.

Replentished my supply of Eneloops from www.hkequipment.net last week. 8 AAs for $29.99. (ordered on 17/2 arrived 4/3 in Aus)

These are the 2nd gen Eneloops Part No 3UTGA (The ones with "up to 1500 recharges" & "retains 75% after 3 years" on the front of the packet ).

I have tested the 1st 4 on a Maha c9000.

Out of the packet:

1423

1417

1417

1410

After charge/discharge at 1amp:

2023

2014

2013

1999

I am running a break-in cycle on the other 4.

(I love these batteries)

Cheers,

I think I love my eneloops more than my flashlights. I have 100 (72 aa & 28 aaa) and I'm still thinking about getting more. I think my next set of eneloops will be those glitter ones since I already have the white, costco, tones, and XX eneloops. I have so many that I don't get to use them but I do maintenance on them with my C9000's. It's just as fun to me. :bigsmile:

You just gotta love them eneloops.

Semi-button top - the button protrudes about 0.1mm from the top of the cell.

Unprotected

Diameter 14.2mm, length 49.9mm. For comparison, an Eneloop with my calipers measures 50.1mm length and 14.3mm diameter. Both lengths include the button.

Capacity at 1A discharge to 3V (Turnigy Accucell 6) - 558mAh. Will try the other three to get average numbers over four of them.

Second Bestinone IMR 14500

Discharge 1A - 559mAh

Third one

Discharge 1A - 566mAh

Well, I have been inspired by you guys and finally got the Turnigy Accucell 6 in the mail.

First test was a Hi-Max 18650 Protected 2600mAh from ebay

Claimed capacity = 2600mAh

Discharge @1A = 2481mAh

68.8mm x 18.2mm

Protected

Turnigy Accucell 6 Charger

Happy with this cell, and will probably get the 6 piece that the seller offers next time. The going counter offer is $34 shipped now?

Last of my Ebay AAA purchase has arived ...

Discharged as they arived :

1/ 53mAh

2/ 41mAh

Charged at 0.5A and then discharged @ 0.5A

1/ 177mAh

2/ 210mAh

What can I say , thats bad , real bad .. Hopefully this will give anyone reading these posts some idea of what there getting when they buy the cheap chinese cells .

I bought some new batteries today

Brand: Woolworths Essentials

AAA 800 mah 4 pack

Price $13.98

These come with a 100 % money back guarantee (which I feel I will be claiming soon)

Initial discharge results at 500 ma.

1. 0

2. 4

3. 2

4.0

These were discharged and showing less than 1 volt.

I am currently charging and then will discharge but I am not expecting good results. They are made in China and it does say they should be charged before use.

Hmm I may be proven wrong

Charged at 500 mah

1. 1.44v 883 mah

2. 1.46v 1061 mah *

3. 1.46v 1091 mah *

4. 1.46v 1196 mah *

* They sat on 1.46 volt for a long time and kept taking charge??

I may see good discharge results. However they are NOT LSD and in real use would be poor I imagine.

results

1. 785 mah

2. 794

3. 814

4. 822

on maha c 9000

Quite good but for the price I'd rather have eneloops. Will recharge and leave for a week and then discharge.

i feel sick when i receive the such table. and some need to fill in the blanks, hahaha

Batteries came from www.szwholesale.com , thank you .

Ok I just completed discharging 2 of the 2200mAh 18700 , well , late last night actually ..

Battery 1 returned 2151mAh @ 500mAh discharge rate

Battery 2 returned 2161mAh @ 500mAh discharge rate

These results are excellent for a 2200mAh rated battery .. Discharge was to 3v termination and started with the battery at 4.2v

PS/ There will be a complete review posted , so this is only the discharge portion .

http://budgetlightforum.cz.cc/node/1929 Xtar Review

Batteries came from www.szwholesale.com , thank you .

Ok , discharged the 2400mAh Xtar cells @ 500mAh from 4.2v down to 3v ..

Cell 1 did some 2468mAh

Cell 2 did some 2485mAh

Now this is quite a first for me , cells actually exceeding stated capacity .. [ Well done Xtar ] , Its late , and I will discharge the 2600's tomorrow .

http://budgetlightforum.cz.cc/node/1929 Xtar Review

Looks like Xtar batteries will be next on my list.

Thank you old4570 for all your hard work and all the $$ you spend to share with us all of these battery reviews.

The first Xtar 2600 built on a Sanyo 2600 has been discharged .. And much like the Sanyo I tested a little while ago Here , the capacity tested was very close ..

2433mAh for the Unprotected Sanyo , and some 2448mAh for the Xtar [ Sanyo 2600 based ] , Im currently waiting to put in the second cell , and I want to time it so it will finish a little after I get back from the Flashlight Meet tonight .

Ok , back from the meet , and the second one went 2438mAh .

Next will be some discharge [ for current ] tests ... , So hopefully will be able to post a review shortly .

Intresting, so far at 500ma the 2400mah cell actually has slightly more capacity than the 2600mah cell.

I guess the 2600mah will kick ass at higher currents though.
