My battery is showing 12.6 - 12.8 V when connected up to my Humminbird. It used to be around 13.5 V. It's a 12V, 12ah SLA. Time to replace it yet again?

Seems OK in that respect. Doesn’t fall much lower than the voltage it starts out with, but I’m twitchy because my Humminbird does not cope with sudden power outage very well at all.

I went through a couple of SLA`s runing my hummer, but I used them until they couldn't hold a charge very well,I guess basically I stuffed them as I ran them too low, I switched to an 18ah to stop that issue
