On lead-acid batteries, there is a parameter called "maximum initial current" which is generally written on it. I have added some pictures of it at the end of the question. My confusion is how to interpret it? Is it:
- The battery can demand more but I should maintain constant current below that limit.
- The battery will never draw more than that current. So, just use a power supply (of course with appropiate voltage rating) which will be able to handle that maximum current.
I think it is number 1 but I need some expert opinion.
Edit: I have an SLA charger which is rated 1A for fast charging and 0.5A for slow charging. (there is a toggle switch for these two modes). Now suppose I have a battery with max current rating 0.33A. Should I use the battery with the charger?
If number 1 is ture then I think I sould not use it but if number 2 is true, then I should be able to use it.
