The BLF Battery Data Base

Please add:

Trustfire 3000 mAh "Flames" - 2494 mAh @ 1A, down to 3.0V; 2445 mAh @ 2.8A, down to 3.0V

All data courtesy of Joerch.

Why are the first 25 or so links (in the "Battery" column) towards the top of the list of the battery pointing to budgetlightforum.cz.cc ???

Because that was before going .com [ budgetlightforum ] + 4 more weeks of school [ something like that ] to complete my Cert 4 in IT

But thanks for mentioning it , I will fix it as time permits ..

Reminder to self - fix links in DB !


Yeah, I thought I had a virus LoL. Every time I clicked on a link I was getting redirected to some random stupid ad site. After doing a full scan twice, I went back and realized half the URLs were just different.

hi, i use a cheap charger (ultrafire wf-188) and cant measure voltages, sorry. but i've got a high quality digital sliding caliper so here are my length measurements:

XTAR 18700 2600mAh (average size: L x D: 69.7 x 18.5 mm)

cell1 L x D: 69.59 x 18.48 mm

cell2 L x D: 69.67 x 18.43 mm

and finally the capacities:

Discharge test runs in genuine Imax B6 at -0.2A discharge rate from 4.200+V (UT61E) down to the B6-standard "3.00V" termination limit:

test run #1 (tested: cell#1): 2501mAh, remaining resting voltage 3.281V recovered after 2 hours

test run #2 (tested: cell#2): 2515mAh, remaining resting voltage 3.390V recovered after 2 hours

Notes:

  • more test runs will be performed at higher discharge rates, e.g. -1.0A to collect more data which can be compared to the literature.
  • the test runs will be repeated in future to see how much the cells have aged

TrustFire 14500 900mAh (average size: L x D: 51.1 x 14.0 mm)

cell1 L x D: 51.13 x 13.98 mm

cell2 L x D: 50.98 x 14.01 mm

(in comparison, cheap AA Alkaline are 50.3 x 14.0 mm; this means that the flamed Protected TrustFire 14500's are 0.8mm longer than standard AA Alkaline.)

End voltage is a bit low on the last as its sat on the charger all day waiting for me to come home from work befor the last picture was taken.

Lidl special AA LSD. Discharged on an Angeleyes charger - I don't own a C9000.

Nominally 2100mAh. First full cycle. Noticed that they got alarmingly hot at a 528mA discharge which is not a good sign. Also I doubt their LSDness - they certainly aren't up to the standards of the GP Recycos I have or the Eneloops. Still too hot to comfortably touch after around 1750mAh discharge.

Just as well they were cheap because they don't look very good. I'll rest them and recharge them then test one at a time for a few weeks to see how they hold their charge. From the heat from them on a 500mA discharge (Eneloops will do 8 amps) I doubt they'd be good in a high-drain application.

i own " BTY Ni-MH 1000, Rechargeable AAA 1.2V " and it says " Charge Methods: Standard Charge: 15hrs at 100mA, Quick Charge: 4.5hrs at 300mA ".

They're in my house phone and all i can say is: my brand name (VARTA) AAA 1.2V rechargeables last 4 times as long as the BTY. And they also get quite warm (in the house phone or in flashlights). Not recommended.

i bought them thru ebay.

BTY cells are junk which is best avoided.

Lidl Tronic cells are little better.

Am I the winner in drag racing an 18650 from 4,20V -> 2,70V in least possible mAh´s? :D

Discharged these at wrong amperage, used 1A instead of 0,5A that was suggested.

1st cycle

Cell 1 : 757mAh

Cell 2 : 662mAh

Seems like I got a bad pair...

I got some batteries from DD , just to see what there selling .. Dek 800 and Sunos 900 ...

Initial discharge = From packet [ 500mAh discharge ]

Dek 1- 351mAh / 2- 386mAh

Sunos 1- 375mAh / 2- 315mAh

After being fully charged , discharged @ 500mAh

Dek 1- 643mAh / 2- 626mAh

Sunos 1- 712mAh / 2- 731mAh

Heard some good things about Turnigy AA LSD batteries , so thought I might buy some ..

Also new DEK2750 [ though it does not come close to claimed capacity ]

Discharging @ 1A returned :

DEK - 1897mAh - 1916mAh [ 2750 claimed capacity ]

Turnigy - 2196mAh - 2163mAh [ Claimed capacity 2200mAh ]

Discharge test with 4 different flashlights ...

Turnigy - 1.75A - 2A - 1.99A - 2.1A

DEK - 1.7A - 1.89A - 1.9A - 2A

Rayovac - 1.75A - 2A - 1.9A - 2A

AccuEvolution - 1.85A - 1.9A - 2A - 2.22A

The DEK from DinoDirect were some what disappointing [ capacity claim ] , on the other hand the Turnigy LSD AA's performed very well , and I would be seriously tempted to buy some more , if your interested in the Turnigy , head on over to HobbyKing ...
