Good to have you here!

Glad to have you here, Sirnic. Way to jump in and contribute!

Aloha and welcome to BLF Sirnic!

Thats it!

I also tested the AA Maxuss 3000 mah batteries. About 1750 mah. But I had recharged them 2 times so they are not new. Don't buy them http://www.dealextreme.com/p/maxuss-1-2v-3000mah-ni-mh-aa-rechargeable-batteries-2-pack-7729

I got an 8 pack of eneloops from an OZ seller. Came in a clear packet- no label or anything. They look legit as far as I can tell. Currently discharging straight out of the packet.

True results wont be known until discharge occurs in about 4 hours.(2 hrs rest - 2 hours discharge approx)

Definately legit batteries code is 10- 08 ? Hard to read though

Maxuss AA 3000 mah from DX

http://www.dealextreme.com/p/maxuss-1-2v-3000mah-ni-mh-aa-rechargeable-batteries-2-pack-7729

Tested 3 so far. 2 cycles

1. 1750

2. 1731

3. 1800

Maha c 9000

Button top

Length 50 mm

diameter approx 14mm. sorry dont have a digital caliper

Very poor performance against claimed capacity. I wonder if they are re badged 2400 or 2000 or are they equally poor performers.

I have some ready to use Varta aa 2100 and 2500. I will not post results as they are not new and have been "cooked" a few times on the 15 minute charger. I noted that the 2100 has been charging for almost 3 hours and the capacity was 2400 mah and climbing. The battery felt overly hot so I stopped it charging. I'll buy a new pack and test soon.

Arrived today : Matsushima AAA LSD [ 80% after 1 year ]

Capacity claim 750mAh min to 800mAh

Will start these ASAP

Discharged straight from the packet :

Cell 1 / 461mAh

Cell 2/ 0mAh

Cell 3/ 429mAh

Cell 4/ 428mAh

Charged and discharged

Cell1/ 679mAh

Cell2/ 692mAh

Cell3/ 702mAh

Cell4/ 714mAh

Just got a pack of Trustfire grey 16340 protected. I'll try to find a way to asses their capacity to contribute to the list.

Soshine 1100mAh Ni-MH Rechargeable AAA Batteries with Case (4-Battery Pack) from http://www.dealextreme.com/p/26987 ($6 shipped), non LSD

La Crosse BC-900 charger. Brand new cells.

Charger Test mode results: 1022 1007 1035 1050 ma (charge 500 ma, discharge/measure capacity at 200 ma, recharge at 500 ma, cool down)

2nd cycle 500 ma Discharge mode results: 1050 1066 1078 1096

I think these are pretty good numbers for inexpensive AAA cells, and they are nicely consistent across the 4 cells. They also get good reviews on DX. They arrived almost 100% discharged.

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 ..

http://cgi.ebay.com/Samsung-18650-ICR18650-28A-2800-Li-ion-3-7v-Battery-x2-/370422727802?pt=US_Batteries&hash=item563eea447a#ht_2260wt_905

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:

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

(I love these batteries)
