OCD Battery Question

[Maverickbo]

I have an X-tar VP2 charger and on the back there is three settings...which one do I use to charge the 18650 Sony VTC4. 3.2v 3.6v or 3.8v. I know they r 3.7v but my OCD is acting up and I can't understand why 3.7v is not one of the selections!!!!!

Because that is charging coltage not the voltage it will hold. a car battery is ~12 volts and the charging voltage is ~15. id use 3.8 volts

Thank you!!!! You have calmed the goblins in my head!

According to the documentation with the charger

3.6 cuts off at 4.2V

3.8 cuts off at 4.35V THAT'S OVER CHARGING!

 

[Maverickbo]

Mrs C ..... So I should use 3.6?

 

[Mrs C]

Yes 3.6 is the one you want

 

[Maverickbo]

Thank you! And the Goblins thank you! Lol!

if thats the case then yes. 4.35 volts would be for icr batteries not imr like we use

3.2 is for LiFePO4 batteries - not what we use.

3.6 is for standard Li-On batteries - THAT ONE!!! USE THAT!!!

3.8 is for 'high voltage' lithium batteries that charge to 4.35 volts - not what we use.

Thanks Rickajho!!!!!

Xtar really could have done a better job. They sorta/kinda implied that the switch settings were relevant to the nominal working voltage of the battery. But when they decided that "3.6" meant the 3.7 everyone usually knows for standard Li-On batteries that kind of screwed up that concept.

For anyone buying a multi-voltage charger like this more relevant markers for that switch would have been the charge termination voltage each setting represented - since that's what that switch setting determines anyway. "3.6" means your batteries charge to 4.2 volts. It's what you want - just try to not obsess about it.

Thanks Rickajho!!!! Goblins are put rest...lol
