hi, i have a 1000va IPS(Instant Power Supply) uses 24v, 7.5AH sealed lead-acid battery. Now i want to change battery to 24v, 35AH for long backup.The charging ckt uses a 1Amp transformer & LM317. I am afraid of the possible effect on the charging ckt due to the change. some people suggest me there is no effect on charging ckt but i argue with this. So pls suggest me what i have to do in this case. thanks
