Note that these energisers contain a sealed lead acid battery (SLA). SLA batteries do not like to be stored in a discharged condition. Storing an SLA battery in a discharged state causes sulphation of the negative electrode which, when left for a month or so, basically kills the battery. It cannot be recovered from this state.
Periodically fully charging the battery is essential in preventing this sulphation from occurring.
