We used to have NiCad batteries and then into LI-ion and some other types.
A lot of people will charge up a battery to use the choice apparatus and then maybe forget about it until they need it next time. Next time, might be a long ways away and most of us either forget about it or think that the battery should still be changed up.
All batteries have what they refer to as an internal resistance and just by the nature of the beast tend to discharge.
Whether you use your apparatus or not, that battery is discharging.
It is recommended that you charge your rechargeable batteries every 120 days (whether it's used or not).
Before you remove the battery or plug it in for charge. turn the item on for 5 or 10 minutes. This will give it a temporary drain and "exercise" the cells prior to a charge. Check the manual to make sure you don't overcharge. Most chargers and cells usually take 12 to 24 hours (an overnight) to resume a full charge.
Even with solar power moon ray type lights the batteries should be removed every once in a while and be recharged, especially when they're exposed to shady or overcast areas.
It would help to bring in those moon rays during the winter months, charge up the batteries and remove the batteries till the spring.
