Hi All,
I would like to use 1.3ah maintenance-free battery float charged with PB137.
I expect 100mA load, with 5A peaks when running motor (max. 5s per minute).
Is it a good idea to cover the current peaks from the battery and recharging it when the load is low? Will it affect the life time?
Thank you.

 

Her is a very good article on charging sealed lead acid batteries. I think it will answer all of your questions:
