Problem with GP charger..

I have a problem with my 2hrs quick charger.

Once I bought my new batteries, I charge it overnight, about 8hrs for the 1st charge.
Aft that, I used it, it does not give me problem while using my Oly FL-36 flash, refresh rate about <=2secs.

After using, I charged it for 2 hours (as the charger is 2hrs).
After it indicates fully charge, I use it on my flash, the refresh rate is about 6-7 secs, sometimes even more.
NOTE: 4 of my batts are 2100NiMh and 4 are 2700NiMh.. All GP brands.


Have anyone faced such a situation similar to mine, before?

Can anyone tell me what's wrong?
Is it a battery problem or charging problem?

Thanks! :D

Just to make sure, your flash is at full discharge in both scenarios? A partial discharge when you use the flash as a fill flash will have a faster refresh time as compare to the full discharge. Just want to eliminate this variable before looking further.

Get a Maha charger & Imedion or Eneloop batteries.

IT show or something like that about 6mths ago.

Isn't those about the same? It's due to the NiMh ratings, I thought? :dunno:

the correct way to test the refresh rate is to set the flash to Manual, select desire GN, then press the TEST button.

have a problem with GP as well, I'm using the half hour charger. initially the batts are a bit unreliable, but the performance should stabilize after a while. make sure you fully discharge before charging until it is stable. i dunno whether it makes a difference or not, but i'd also not mix the different batts together when charging. meaning 2100 and 2700 charge separately. hope it works.

Yup. I know it's better to discharge before charging again.
Now I ignore the "2hrs" charging time.

I leave it to charge for about 5hrs..
Don't know what's the diff? :dunno:

Maybe trying it out soon. ;)

The Quick Charger 2hrs, usually means 2 batteries, thus 4 batteries usually is 220mins, at least for my GP Recyko, saw the Sanyo Charger with similar rating also, 2 Batteries 120mins, 4 batteries 220mins.

Slower recharge time might be due to insufficient power.
