I got 5.5 years.... lots of short daily runs with very long runs every 2 weeks.
Have 2 Optimas hanging off the Traxide which has helped extend life, as well as a Charging plug I flick into the White 12S every now and then to give them all a good top up.
Just started having no-start scenarios (USI-160 jump feature to the rescue) so went and sourced an Odyssey as a replacement.
What a cracker (I've used them before so knew what to expect) and it's proven the best battery upgrade!
Being able to take huge inrush current means it recharges far, far quicker so short runs have it happy...
On a long run, the primary is fully charged and the Optimas topped right up in a very short distance...
One of the best bang for buck changes [emoji41]
