As with all of you i am facing the same problem of power failure / power loading shedding (one hour on and one hour off) and therefore it is diffcult to work online without a generator or a ups which i cant afford right now.
So here comes the query.
Can I make a dsl modem work on a battery
I have a dsl modem 9V and 0.5A.
What i am planning to do is to replace my emergency light's battery with a 9V battery ( the emergency light's battery is currently of 6V). I have to also change the tubes of emergency lights to 9V if i want to use both the tubes or one tube if i am not using the modem (right?).
The emergency light has got the charger builtin so i am supposing that it will charge the 9V battery as well (right?)
Its simple to take out two wires from the battery and plug it in the modem making it uninterubted. The only thing which i cant understand is that
Should i have to get a battery whoz initial current is 0.5A?
whats this 0.5 A thing on the modem?
Also please inform if 9V 4.5AH battery is good enough for one hour back up if fully charged or should i go for a higher AH battery.
I am a noob in this thing so am am stuckup with the 0.5A thingy??
The battery which i already have in my emergency light states
6V 4.5AH Maintainance free lead acid battey.
Standby use 6.75- 6.90 V
Cycle use 7.20 - 7.50 V
Initial current: less than 1.35A
so i suppose that the replacement battery should be like this
9V 4.5AH or higher Maintainance free lead acid battey.
Standby use 9.75- 9.90 V (dont know what it is)
Cycle use 10.20 - 10.50 V ( dont know what the hell is this too)
Initial current: less than or equal to 0.5A ?? (is it so)
Also i guess i have to search for the tubes which i will replace in the emergency light with 9V and 0.5A current. (Confused about this too)
I am using a laptop which gives me a good backup of 2 hours with an hour of charging.
I want to do uninterupted work and without installing ups as i do not have a budget for that.
Please advice what to do?? (what specs battery to buy)
