The point is that I am not changing batteries out every 2 days like 18650 and aaa battery users are.
You didn't answer my question. What's the rating on your 6v SLA
battery (amp-hrs)? How many hours does it it run in your 3 month
cycle? Efficient DC-to-DC switching regulator or inefficient LDO
linear regulator to get from 6V to 4.5V (or just 2 diodes in series)?
I don't believe that you can do a 3 month charge cycle with a 13 watt
lighting system and a realistic number of hours of operation per day.
That's why I did the calculations errr... guesstimations.
