Microsft/Office Depot screwed us over for about $99 by
selling us a copy of Office which turned out
to be nothing more than a trial
Others apparently complained too since Office Depot is
now posting a sign warning customers.
Same is true with Windows

message to the effect that if you want a firewall then you must purchase a copy
of its software.

|Project goal is to solar charge G580 battery directly or charge a
12 V lead/acid then connect the G580 through an inverter.
Linear Technology manufactures a comprehensive line of high
performance battery charger IC for any rechargeable battery chemistry,
including Lithium-Ion, Lead Acid, and Nickel based.
Lithium Ion Charging Basics
These remarks apply
equally to lithium ion and lithium polymer batteries. The chemistry is
basically the same for the two types of batteries, so charging methods for
lithium polymer batteries can be used for lithium-ion batteries. Charging
lithuim iron phosphate 3.2 volt cells is identical, but the constant voltage
phase is limited to 3.65 volts.
The lithium ion battery is easy to
charge. Charging safely is a more difficult. The basic algorithm is to charge
at constant current (0.2 C to 0.7 C [?] depending on manufacturer) until the
battery reaches 4.2 Vpc (volts per cell), and hold the voltage at 4.2 volts
until the charge current has dropped to 10% of the initial charge rate. The
termination condition is the drop in charge current to 10%. The top charging
voltage and the termination current varies slightly with the manufacturer.
However, a charge timer should be included for safety.
charge cannot be terminated on a voltage. The capacity reached at 4.2 Volts per
cell is only 40 to 70% of full capacity unless charged very slowly. For this
reason you need to continue to charge until the current drops, and to terminate
on the low current.
It is important to note that trickle charging is
not acceptable for lithium batteries. The Li-ion chemistry cannot accept an
overcharge without causing damage to the cell, possibly plating out lithium
metal and becoming hazardous. [?]
Safety Every lithium ion battery pack
should have (must have?) a safety board which monitors the charge and discharge
of the pack, and prevents dangerous things from happening. The specifications
of these safety boards are dictated by the cell manufacture, and may include
Reverse polarity protection
temperature--must not be charged when temperature is lower than 0° C or
above 45° C.
Charge current must not be too high, typically below
0.7 C. [?]
Discharge current protection to prevent damage due to short
Charge voltage--a permanent fuse opens if too much voltage
is applied to the battery terminals
charge when voltage per cell rises above 4.30 volts.
protection--stops discharge when battery voltage falls below 2.3 volts per cell
(varies with manufacturer).
A fuse opens if the battery is ever
exposed to temperatures above 100° C.
[Can we do this? And not have
failures, of course.]
