Hi, Can someone advise on different ways to recharge this battery http://www.bb-battery.com/productpages/BP/BP5-12.pdf. Outside project. I have 3 of these batteries. Do I just charge with standard car battery charger? What should I look out for please? I need to charge all three and take to event.can then charge them at home for future use. Can I use a PC power supply to charge them?
My project needs to power an UNO , 7 digit 7seg display with 8v forward current req for each seg. 20plus LEDs at various times . The 7 seg and uno will be on for 5 hrs or so. The 20 LEDs on for seconds at a time then off.
