Battery Backup Guide

Karl asked:


It says battery backup and has a spot for a 9 volt. Will it run on just battery with no electricity for very long?

JAFOOLY asked:


What would you like to see? People say get a backup battery pack thing, so you charge the thing that charges your iPhone.

STL Biker asked:


Isn’t one type of battery better than the other? Why don’t all electronics use the better battery and which type of battery is the better battery?

Bekah P asked:


does anyone know where i can get a polaroid battery for my portable dvd player its a model no:BT45 BC7.4V rechargeable battery pack

Mstrr asked:


It says in the manual to only use alkaline batteries, however I want to buy rechargeable batteries for it to limit the waste.

I can’t find anything in the UK that can charge alkaline batteries, so would it be ok to use another form of battery, like rechargeable Ni-Cd or something in a toothbrush that says only to use alkaline?

By the way it came with the 2 non-rechargeable alkaline batteries that are suitable which are 1.5V.
Any help would be greatly appreciated.

How to use car battery or any other battery to lighten the tubelight at home?

Or is there any other means to lighten the tube light using battery?

hipp5 asked:


It’s said that if you want to prolong the shelf life of a battery you should put it in the fridge. That makes sens to me because it’s slowing down the internal reactions of the battery.

However, whenever I walk to class with my laptop in the winter or have my camera in my pocket in the winter it significantly decreases the charge on the battery. Why this contradiction?

adam s asked:


I want to buy protection for some high end DJ equipment, and was wondering if it was worth it. A surge protector i need would cost around $25, as opposed to one with a power conditioner in it for ~$100.
Is it worth the extra $75?
Thanks in advance!
Thanks for the great answer! Ill just buy a regular power strip!

niknak3 asked:


I was thinking of buying a monster surge protector with a cleaning power of 1 (what does that mean?) and 1680 joules (but another one is 1300 joules. Which is better, or am I overlooking something. I am going to be connecting my xbox 360, my new lcd television, and other things. Any help is appreciated, Thank You.
