Well I was happily playing with my DX 150mw baton style and then it just stopped lasing. From really strong to nothing :'( The blue LED still works though :-/ I have even checked to see if any IR was there and none :'( Is the diode dead? It just stopped lasing instantly... It hasn't been 30 days since I bought the laser so does that mean I could get a refund? If so i'll use the refunded money and buy a nova lasers X series.... Please help me :'( It breaks a few days before the ban :'( I have never dropped it and I only let it get warm before turning it off...

with my 250mw red,it happens alot. it will be burning like hell,then just dim in 1 second. All ways coem to the conclusion to first check the batteries before any other step.

That happens with my RPL and protected 18650 batteries. It will be lasing happily one second and the next it completely shuts down except for a slight glow from the LED.

Charge the battery and see what happens.

I thought the protection circuit stops power completely at 0V :-/

Not much power at 0V. ;)

Deep depletion protection on protected NiMH batteries kicks in below 0.9V. Not sure about Li-ion cells.

Yay I charged the battery last night and this morning it worked again! :D The wierd thing is I haven't used it much but the battery still drained faster.... :-/

is your charger one channel?
i realised my charger is one channel for the two batteries... so it was done charging but in fact it was done when the first was done, the second wasnt full at all...
so my laser "died" when the non-full battery died...
so im charging them to full separately so that next time the charge should be around equal

Yeah lithium batteries get out of balance insanely quick (which is why my heli has a balance charger, it was a PIA when I didnt have one), however is they are nimh and nicd they shouldne be getting out of balance, I have some 5 year old nicd packs that have a boatload of the memnory effect but they are still nice and balanced...countless cycles.

How long did your batteries last you? and which ones do you have...the thing is that your greene is probably powered by a >0.5W IR diode probably over 1w which has a definitive contribution to the speed with which your laser eats through the batts...


Thanks

ALWAYS CHECK THE VOLTAGE !!! i always get out my multimeter and check the voltage on the batts,after i charged them. you never know what voltage that battery is at unless you check. that's how some laser break.

well you can get a cheapo multimeter at a shitshack near you. for 8$ you can get a analog multimeter.
