Yeah, that's my problem.
A 9V DC source feeding a circuit
which I need to add a UPS.
My 9VDC supply's output is a little
over 9V.
The circuit draws 200 - 250 mA.
Need the UPS to hold the unit working
for at least 4 hours (option to 24 hours if possible)
Price is definitely an
issue.
1) Are there inexpensive 9V
rechargeable batteries for this current, in the market ? If so, can anyone point
me to a (very) inexpensive charger solution ?
2) Any other good solution
?
TIA,
