Topic: 722 battery questions?

[F.O.Bean]

so teddy graciously sent me two batteries for the 722 PLUS a lenmar double charger and i was wondering, how does one know when the batteries are done charging?

there is a green light on each battery in the charger, does it turn red or simply turn off

[Craig T]

red while charging, green when charged and ready.  I have the double charger and I think the instructions said to leave it charging for an extra hour or 2 when the light changes to green.

they should show about 8.0 V on the 722 meter when fully charged.

craig, with taht lenmar omnisource udo charger, how long does a battery take to fully charge? say a 6500mah battery?

[fozzy]

lenmar.com says  750mAh in 2 hrs.

375mah

6500/375= 17.3hrs

Seems kinda excessive.

7000/375= 18.67hrs

Seems kinda excessive. 

really? WOW, that pretty much sucks

The lenmar mach1 isn't much better @ 1500mah.  still would take 4.3hrs.

The internal 722 charger charges a 1000mah

thanks fozzy, so about 7 hrs for a full charge on a 6500mah in the 722

Yea, I never run mine down that far so generally after a few hours the top & right will go to solid amber instead of a brief flashing amber.  This indicates the unit has stopped charging.  I like to unplug the ac for a second and then re-plug it in to top em off.  A rough estimate would be for every hour you record an hour of recharge time is required.

I don't know why they make these li-ion charges so underpowered since the technology can handle a 1C charge rating.  ie.  a 4000mah batt can be charged @ 4000mah, a 6500mah battery can be charged at 6500mah, etc...  Should never take more than an hour to recharge a battery no matter what the size.

thats what i thought, all of the charges, well most of them, charge at 650mah max
