My latest BATTLOG Graph!

20 Oct. to 21 Jan. (63days!) |
7.3Hrs |
This time, over 2 months, 63 days very long-run. My usage is also checking my schedule, quicken, file transfer,... this way. NO FLASH this time also.
I'm surprised that my HP200LX run so long time. I almost forgot when I charged batteries last time. HP200LX is great !!!
Compare to last-time graph, the graph is following.
As I said last report, HP200LX eats some little battery power while power OFF. It's about 0.3 mA to 0.5mA. So, in this case,
THIS TIME 0.3mA x 24Hrs x 63days = 454mAh
LAST TIME 0.3mA x 24Hrs x 39days = 280mAh
power may be eaten by HP200LX.
Compare to last time,
| Compare | Days | Run(Hrs) | RS232C(Hrs) | IR(Hrs) | On/Off(Times) | mA | Guess RS232C(mA) | Guess Total mA |
|---|---|---|---|---|---|---|---|---|
| This time | 63(454mA) | 7.3(219mA) | 1.0(?mA) | 0.0 | 64 | 673mA+a | 22mAx1.0=22mA? | 695mA |
| Last time | 39(280mA) | 10.0(300mA) | 5.2(?mA) | 0.0 | 98 | 580mA+a | 22mAx5.2=114mA? | 694mA |
I tried solve out how mush RS232C eat power, but this might be incorrect. Anyway, I'm going to try solve some parameters based on my experiment data collection. I want to measure battery capacity with some equipment, but I don't have any.
Following graph is charging phase.Generally, it need 1.5 times of battery capacity to charge full it. So my batteries must have wanted to eat MORE :-)
