So, I've made the fatal mistake of performing several upgrades at once, and I could do with some advice on where to go now... is my problem with charging time and battery life my new SSDs, my new OS, or something else entirely? Generic snowflake details to follow:

I'm trying to resurrect an old Casio CPS-85 88 key keyboard. When it was given to me, the power jack was cracked, so I desoldered it and soldered on a new one. No luck; I can't get power (even with a different power supply). So I'm stuck running off of a lot of D batteries. As using D cells is both wasteful and expensive.is there any way for me to rig an external power supply to the battery terminals in a safe manner?

I would like to learn more about large-scale UPS systems, particularly the battery strings used in traditional RBOC/Telco applications. These are the sort of beasts that use huge strings of 6V 220aH deep cycle batteries, or even large numbers of 2V 400aH batteries on very strong earthquake-resistant shelving wired up to create a 48V mega-battery. Can anyone point me to the most definitive reference materials on the subject?

I have a 850va 425w UPS battery backup with only 2 outlets. There is a small server, speakers, home theater projecter, lcd monitor, and router connected to a power strip. The power strip and a desktop plug into the UPS. Is this setup safe? I am concerned about short 1-second interruptions caused by bad electrical connections rather than power outages.

Power Inverters for cars -
the thing you plug into your cigarette lighter, with a regular wall-plug on the other end. I bought one last night, for use with gadgets on a road trip. Thing is, they offer two types, excuse the B-st B-y links:
this one (95W), which I bought, and a stronger one (150W)
here - Question is, I went with the smaller cheaper one but I know nothing about power use for things. Should I return it for the larger, or is this sufficient power to charge a laptop, camera, PSP, ipod, etc? Mostly concerned with safety to equipment and car's electrical system. THANKS FOR YOUR ADVICE.
