I used to have a Sonic Impact T-Amp. It was incredible - a great-sounding battery-powered amp with an input for iPod/CD that could drive big speakers at volume. Mine broke and I think I might have thrown it away, which I regret. But in the meantime, is there something similar on the market? A small, great battery-powered amp? I'm based in the UK but would order from the States if needed.
It seems the ac-adapter plug thingy (i.e. the cigarette lighter) doesn't work in my car. I suspect a blown fuse. I have neither the time nor the inclination to take it in to get fixed if I can do it myself. Halp? [more inside]
Do you trust third-party batteries for your cellphone? Specifically I'm thinking about picking up some spare batteries for the HTC Evo, but I've been a non-removable battery phone user for so long that I don't know if I really should stick to the manufacturer's branded batteries or can safely save some money and look elsewhere (like a Seidio, for example).

Battery shelf manufacturers: I need links to manufacturers of steel battery shelves for large DC UPS applications, for use with AGM VRLA lead acid batteries such as 2V 600aH to 1200aH and 6V 220aH to 600aH+ sizes. Batteries will be Rolls or a competitor. The shelves should knock down into something that can be flat packed and reassembled at an installation site. Features for earthquake bracing and shock mounting are also useful. Where do the US RBOCs buy their shelves?

I need a replacement battery for my Asus 1000HE netbook. I've been looking on Ebay, and it looks like they have some 12-cell batteries, whereas the original I got was (I think) 6. Does anybody have one of these, to know whether they're a good deal, how much bulk they add to the computer, etc?

Help us diagnose our Ford F150: what could be draining down the (new) battery overnight? We're suddenly seeing apparent battery drainage in our pickup truck, a 1994 Ford F150. Though the truck starts up fine, the dashboard battery gauge reads low immediately upon ignition, the windshield wipers are sluggish, and the dashboard lights are dim. We thought the old battery was likely dying, so we had it replaced with a new battery... but that hasn't solved the problem. [more inside]
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?

iPhone battery life: I'm flying across the Pacific tomorrow with a 2 year old and a 5 year old. They are iPhone fiends (god help them), but I need to know if there is a huge difference in battery consumption between the education apps they usually play ("Find the sheep"..."Baaaa") and videos. I suspect that videos will use up battery life longer than these really simple apps, but I'm not sure. Anyone know?

I just changed my car's old dead battery with a new, just purchased one following the directions here.

Any ideas what could be wrong? [more inside]

My 18 year old son went to Express Oil Change to have a new battery put in his 2004 Ford Explorer Sport Trac. His battery was dead and when jumped off, it would not hold a charge. They put an MTP-65 Interstate battery in and charged him $146 for the battery alone. With installation, charging system testing fee, and taxes, the total cost was $208.93. Does that sound high? I was expecting to pay half of that.
My Aspire 3680 (crappy laptop PC) doesn't want to hold a charge anymore, with either battery. How do I determine if it's my laptop, my batteries, or my charger? (I have a VOM and know how to use it).
