Hi,
I have a 12V DC 1500mA supply (Non regulated output) built with 1 simple step down transformer, two 5480 rectifier diodes and one 2500mFD condenser. I use it to power a heater element that protects my Telescope lens from dew deposition in outdoor works during winter. Now I want to use it to charge my Sealed Lead Acid battery of 12V 7.5Ah. too.
I have learnt from the posts of senior members of this group that the charging current for a SLA battery should be 1/10th of its Ampere hour capacity. And the charging Voltage should be battery voltage x 1.2. So, for me, it should be 700mA. 14.4V DC.
With the help of senior group members, even with my novice workmanship, I could successfully build a regulated output charger using LM341 for my 6V SLA battery. Is there any way to use LM 341 to regulate the output voltage and current both for my 12V supply that can be used safely to charge my 12V battery? Please help.
Regards and thanks in advance-
