hi,
my dirt bike uses a small battery(lead-acid) of 12v 2.5Ah.
as i haven't used it since 1year,it seems the battery is quite dull.so i want to build a simple charger for it(13.8v charging voltage for 12v battery).
i did some search and found below to circuits.
**broken link removed**
**broken link removed**
one uses LM338 and another L200.can u guys tell me which one of these is better and safe,if iam planning to charge the battery for around 8 to 10Hrs.
thanks in advance
