Another battery question - oh joy - i hear you cry!
following on to my previous thread..
we need replacement batteries!
Question part one..
our current 2x 110ah batts are sealed, unbranded and 52cm(l) x 26cm(w) x 15cm(h) and look like this...
We can go higher, but not longer or fatter! The terminals are bolted into the batts as in pic. Would rather not have to change the terminal fittings to fit different terminals but maybe this will have to be done..
We are pretty low use liveaboards, (240v fridge, 600w inverter, led lights, lappy, NO tv or hair straignteners - no hair!) attatched to shoreline most of the time.
We have 2x 140w panels going through a Victron MPPT 75/15 controller to keep them topped up - has worked well for 3 years.
Replacement battery recommendations?
Question part two...
How do i disconnect them - do i have to wait till dark or cover the solar panels up? The MPPT controller has a 20A fuse in the bottom, what does this do? Can i just pull it before disconnection? The manual for this isn't helpful..
There is a vague chance that only one battery is fully sha*ged, and we can get by "for now" on one only - but again - i dont want to nacker anything by not disconnecting the solar before starting to unbolt terminals - also, should both battery switches be "off" before attempting to disconnect anything?
Sorry for the tedious need for some hand-holding; all above is asked in the spirit of "the only stupid question is the one you DON'T ask!!!
