slow charger

My chargers seems dreadfully slow, it is a Trustfire TR001, this puts out 500mah, I also have a Ultrafire WF139 that puts out 450mah.
Is this not much output as chargers go ?, to charge up my CR123’s, 1440’s and 18650’s.
I did think about a newer(better ?)charger like the 6 channel xtar one.
Your thoughts would be appreciated with regard to output and whether there is any advantage to going newer, thanks

An SP2 is a good choice for multi-current selections. That one would be good for 14500s, 16340s, but would be a bit fast for 10440s and a bit slow for 18650s.

Buy more batteries :

500mAh is a decent charge rate , and is a little high for the 10440 [ Over 1C ]

18650 - yeah they can be charged at a higher rate , but you may not see that much difference actually .

Its a funny thing , charge rate is relates to battery voltage , if you pop in a empty cell [ 3.5v resting ] you might see 1A charge rate , but as you approach 4v it will rapidly drop off to maybe 300 to 500mAh and once you go over 4v then it might be down to 300 or less , and depending on the curve its working on , that last few 0.1volts can take [ depending on charger ] a few hours ..

Im still waiting for the day, some switched on manufacturer adds a voltage meter to the charger [ for each bay ] so users can visually decide to terminate the charging process .

In my test of the SP2 I got the following charge times with a 3100mAm battery:

0.5A charge rate: 6.3 hours

1A charge rate: 3.7 hours

2A charge rate: 2.3 hours (Current is double of recommended charge current).

I will call it a significant difference.

Yeah , thats one charger , and 3 different charge rates ..

I was thinking more TR001 VS TR003

Have you ever run discharge tests after the different charge rates? I’m curious as to how much more charge the batteries hold at a slower rate.

Not for this charger. Generally the energy is not depend on the charge rate, but on the termination current.

The SP2 uses different termination current for the different charge rates, i.e. it will put more energy into the battery at lower rates.

I have started on a more general test of charge voltage and termination current, but my equipment has been to busy to finish it.

Thanks for that, and other peoples replies, this charger is one that I had been looking at, but I hadn’t even noticed the charge rate was better, as suggested might be better for me to buy some spare batteries, I’ve got 8 on their way so probably for now anyway won’t need the charger just yet.
Thanks for replies peeps,
