Acc. to ur requirement for electrical component u have in corolla (corollahaving an amp, hids,remote shade, trakker cng.) 7 of course also count a/c i will recommend u to go for atleat 60Amp. better will be 90 AH but 60 A is atleast ( if u have low budget)
U can go for Bosch
@insaan is 100 % right,
even in Pakistan i saw some pupil having "AC delco" batteries , they r more better than Bosch
try to find acdelco if not then go for Bosch
i also heard Panasonic dry batteries r more good but remember only look for maintenance free dry batteries
