UltraLite 10440 batteries

How do you handel IMR10440 3.7v 350mAh?
A 10440 battery is supposed to be 350mAh and is charged on 300mAh/3.7v setting on the Ultrafire WF-188.
On several other sites they recommend other chargers like Trustfire TR-001.
Will it not ruin the batteries faster? If not why can't they be charged in a PILA charger?
How far down do you people let them go before charging, I'm down at 3.2v when I need to charge them. should I do it on 3.7v minimum instead?

I just wait for them to go completely dead, and then charge them on the WF-188 charger on the 3.7v setting at 300 mah. I haven't had any problems with them at all that way.

OK. but what if you charge them at 500-650mAh? If they can handle that why is it not possible to charge them in a PILA? The reason I ask is I have 17670 batteries to and I'm worried that I forget to change the setting to 300mAh after charging my 17670 batteries. I'm also considering to by a PILA because the WF-188 does not charge them to 4.2v.

I'm not sure about that. I don't know exactly what a PILA charger is. I will look it up and find out if you can charge the 10440 in the PILA charger for you though.

Thank you It's OK. You don't have to waste time for that. I'll ask around on flashlight forums instead. I don't know if it's OK to post a link for a PILA but it's easy to find. The PILA charges Li-Ion batteries as they supposed to be charged.

After reading the info that you sent me, I would probably stay away from using the PILA charger for the 10440. The 10440s don't have a very great battery life to start off with, and the only way you would be able to know if they were half dead is to constantly check them with a voltage meter. It just seems like too much work. Just my opinion but I would just stick with the WF-188 charger, or something similar.

That was exactly what I was afraid of and I think that is true even for other +500mAh chargers.

Yeah so I think your safest bet would be to stick to the WF-188.
