Trojan T105 batteries have become much more popular in the last 3/4 years. They are high quality, have a capacity closer to what they are advertised at, are good value and have a long life if looked after.
Typically 4* Trojans will replace 3* standard 110AH leisure batteries.
On this job 3* Crown 155AH batteries were replaced with 4* Trojan T105’s. 50mm link leads. All loads taken across the bank (which is sometimes hard with the standard short studs with less room for the terminals). Crown batteries are excellent quality but have only lasted 3 seasons of light use which is pretty poor. I think this is partly down to the original fitment of a Beta Alternator controller (on Beta 43). I removed this and fitted a standard Iskra regulator which gives higher charging voltage over a longer time.
Smartgauge also installed – simple to fit and use, and relatively accurate battery monitor.
