Hi

It seems that the circuit I originally came across then is not really suitable. Whist my kids at the moment understand that the toys need feeding (charging) and sleeping (dad's siesta); 160 hours is a little long

I have done some more scouring around the internet and came across this link.

Would this be a better starting point? Although I'm not sure what component T1 is.


I spoke to Yuasa about their data sheets and you guys are correct in that the 6 volt battery charging voltages are wrong. The volts per cell is correct though.

Thanks for your help.

Nick.

 

Hi

I've also just found this circuit.
http://ebatterychargers.com/lead-acid-car-battery-charger-20.html

This circuit has the switch to select 6/12v and the LED's to indicate charge/float.

Do any of you see any issues in this circuit and would this be a good circuit to use?

Thanks for your help.

Nick.

 

Nick, my cold/flu has turned into bronchitis, and I'm really feeling like dog poo today.

I'm not up to evaluating the circuits on the links you posted.

 

Hi

Sorry to hear about your bronchitis. I hope you get well quickly.

Not to worry about having a look at the links. The second one is very close to what I'm after and it appears to use common components, so I may have a go at building it and seeing what happens. If you do get a chance then great I'd love to hear from you; I and many others appreciate the effort that you go to in helping us out with stuff.

Nick.
