We carefully hoisted our lead-acid batteries into the dinghy of a fellow-sailor. He is happy to re-use them, and we are happy that they don’t have to be recycled yet. So, we are both happy. The alternative would have been to sell them as old lead, but we prefer re-use to recycle.
Why did we decide to replace the batteries? Well, we noticed our lead-acid batteries got more difficulties in loading and unloading. They also needed more energy for themselves, so they were less efficient. Also, because we could not travel during COVID, we decided to use our time on Guadiana river to replace the batteries. After giving it some thought we knew we wanted to change to lithium-ferro-phoshae. Lighter and much more efficient. So, in January we ordered batteries and… lead.
Work in progress: taking the old batteries out and replacing them with the new ones.
The next phase is the that we have to connect the battery-banks to all our energy-input systems (solar, hydro, wind). We hope to be able to tell you how we did this in one of our next blogs.
