You are the reason DIY is dead. You can't or won't pass your experience or knowledge down to others.

One a side note: a SLA battery he is talking about is a personal UPS/alarm panel 12VDC battery from Batteries Plus.
From what I can tell, the charger looks like a laptop power supply (brick).
This is easy to build if you have a car radio or spare battery laying around. Just want safe in the operation of batteries, hence the questions.

That size battery is the most common one that is used not only in UPS applications, but many other devices. It does not have to be that exact one, but it is usually the biggest bang for the buck because of competition. The charger is not a laptop charger but a charger specifically designed for SLA batteries. As I said there are lots of them on the web. Most laptop power supplies are designed to work with lithium batteries and will not work with SLAs.
