Stored Energy ( MM553)

We were intending to go for a bike ride today but discovered we had left the bike chargers in the motorhome,  so a short ride to deliver the parish magazine and a few jobs around the house.  I cleaned the inside of the car and put the jump starter on charge.  I've never been convinced about the 'smart alternator' as I don't think it keeps the car battery charged up enough.  Having said that,  its not failed to start so perhaps I should trust it more.    I keep this jump starter in the boot, which is probably why it does always start :-)

Thanks to ApolloFly for hosting Mono Monday on the theme of Energy.
