Hi,
i want to make a battery charger, but first i want some info, please...
1) Are battery chargers conected up in reverse polarity as i think they might be...
2) Most battery chargers take 8 hours to charge the battery, but i saw one in the shop that garunteed a full charge in 15 mins, how do they do it (do they increase the voltage or the amps)
3) What voltage and amperage do i need to charge batteries.
4) Is there anything else i should know?
Thankyou
