Seems my long rest has killed my Deca Battery so time for a new one. As a check on costs, I rang Battery World and asked for the smaller of the 2 batteries used in Laverdas Ext16L and nearly collapsed when the bloke said $329, seems they have gone the way of The Oddasy batteries and priced themselves out of the market. The story he told me was the distributor lost a container of THAT SHIP that lost 30 containers off the coast of NSW a couple of months back and they're really hard to get. The bigger model is an eye-watering $379. I am hoping Yogi's account with the distributor reduces this to something more reasonable.
