Ultrafire protected 14500 in wf-139 question

[hyperloop]

Hi all, just got a Ultrafire wf-139 charger and 2 x 14500 protected cells, i have a question.

When charging them, i'm getting a strange sequence in the lights, first the indicators showed green, then i put the cells in, now they're showing:-

green for about a second; then
red for about a second; then
green/red (the charging blink).

then it repeats. Is there anything wrong with either the cells or the charger?? I'm actually leaning towards the cells cos i actually got this wf-139 for my 18650 light (using trustfire protected 2400 mAh cells on those and they're fine).

could use some help here, thanks!

Sidebar: any idea when spacers will be in so i can consider getting rcr123 lights?? i live in a flashlight wasteland (singapore) and getting these parts, batteries and lights in are a bit of a hassle. Also i'm quite the technically challenged type so opening the charger to do some soldering etc which i read about is quite daunting.

There are a couple of ways to get RCR123 cells charged in the wf-139.

• Kramer5150 made his own spacers by taking some wooden dowel and put a screw through it so that it makes contact with the end of the 18650 bay.
• AW sells his spacers seperately over on CPFMP
• 4sevens sells AW's spacers (round metal balls)
• You can get some 1mm x 9mm rare earth magnets at DX and "extend" the batteries.

OT, but I'm going to have Baba O'Riley in my head all day now.

red/green blinking is normal during charging.

red/green blinking is normal during charging.

yes, i know that, its supposed to go that way and turn green once fully charged.

but what I am getting is: -

1. red/green
2. green
3. RED

then it repeats

Do you have a voltmeter? If so, try measuring the voltage hitting the cell while on-charge.

unfortunately i dont have one, think i will have to order one then, what do u mean voltage hitting the cells while on charge?? im quite the non technical person, buy the light, buy the cells, charge the cells put the cells in and click the switch
