Test / Review: 18650 Hi-Max 2600 mAh battery

I brought a pair of Hi-Max 2600 mAh batteries to test, i never had much luck on ebay with torch related products but these are good. They took 16 days to get to me in australia.

Cell A 3.79 volt out of the packet, Internal Resistance 149 milliohms

Cell B 3.79 volt out of the packet, Internal Resistance 161 milliohms

Cell A Discharged to 3 volt and then i recharged at 0.5 amp

Cell B Discharged to 3 volt and then i recharged at 0.5 amp

A quick description of the above tables

Zenit [s] is time of the charge, it is updated every 2 seconds.

Input [V] is how much volts my power supply is giving my Ichager 106B+

Voltage accu [V] is battery voltage

Current [A] is how many amps the charger is charging or discharging the battery or batteries.

Capacity [mAh] is how long the battery will last under load. A 2500 mAh battery should be able to give 2.5 amps for one hour till empty.

Thanks Benckie for the tests you've done so far.

Will you also discharge with 1A and 3A?

Thanks, im going to do a 3 amp discharge test on all the cells ive tested sofar and the ones comming up.

Tail Cap Current Draw Comparisons Of My P60 Drop-in

solarforce 2400 mAh (A) 1.67 amps

solarforce 2400 mAh (B) 1.67 amps

Ultrafire (grey) 2400 mAh (A) 1.23 amps (from buyincoins they only take 900 mAh)

Ultrafire (grey) 2400 mAh (B) 0.7 amps (from buyincoins they only take 900 mAh)

Trustfire Flames 2400 mAh (A) 1.51 amps

Trustfire Flames 2400 mAh (B) 1.50 amps

Redilast 2600 mAh (A) 1.70 amps

Redilast 2600 mAh (B) 1.71 amps

Hi-max 2600 mAh (A) 1.44 amps

Hi-max 2600 mAh (B) 1.45 amps

Panasonic NCR18650A (A) 1.69 amps

Panasonic NCR18650A (A) 1.72 amps

This is for comparison only generaly cells that have the lower internal resistance have the highest current draw. But bad cells can also read high due to high internal resistance and or bad voltage drop ive found.

Excellent comparison!

There is only one cell that I wonder how it would do compared to all those, the SANYO UR18650FM

We sure do thank you for all your time and effort in doing these battery tests. Great job by the way. Looks like they are very good batteries. And it looks like I will be ordering some more of the Hi-Max and Trustfire flames. Thanks again.

3 amp discharge test from fully charged

Cell A

2297 mAh

Cell B

2305 mAh

They did good

If people are wondering how i come up with the above data table's i posted on this battery test, i data log using my icharger 106b+ connected to my computer for my battery tests, i use a program logVeiw V2.7.4* with icharger 106B+ with firmware v3.14 upgrade and then recalibrated the charger.

I use this program for my data log,s and for the data charts i post

I use the data tables instead of graphs becuse i find it simple and think it would be easy for other people to read and the data tables includes charge time updated every 2 seconds, voltage, watts, engery, mAh, plus induvidual cell voltage for upto 6 cells, internal temp of my charger, battery temperture, the chargers imput voltage from the power supply and so on and i can not get all that infomation on one graph.

I usualy only include the end of the charge cycle then hit the print screan button on the key board while the logVeiw program is running and opean on the screan of my computer, then crop the image down with microsoft picture it! i cut out things like battery and charger tempture and induvidual cell voltage if im only doing one cell at a time to test.

I'm open for suggestions for other tests on these batteries if there is any intrest ?, im not sure on how low these batteries can go 2.75 volt ? i have not found any data.
