12v - Lead Acid Battery charging from laptop psu


I working on a new project of running couple of low power devices from PicoUPS 120 ATV:


pico


The review by this guy: Building a 12V DC UPS


Is this correct, this does not regulate the output voltage, the only thing it does is charges the battery and switch between input sources.


I am using a single maintenance free 12v@10Ah Lead-Acid battery (new).


I am using a regular old laptop power supply, rated for 19V DC 4.42A but the charging current itself for the battery was 4.5 A as I checked. I have found other post here stating that for lead acids this should be about 10-30% of the capacity so about 3A in my case.


Does anyone else have experience here with PicoUPS who can give me some advice how to implement this safely?



Thank you.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
