Extending Battery Life

Battery life can be increased greatly by frequent charging. If a battery is totally
discharged before being recharged it might be cycled (charged and discharged) only
180 times before it becomes unusable. If this same battery had been charged more
often (for example at a 30% depth of discharge) it could be cycled over 1200 times. This
is a life increase of more than six times.
If a battery has been stored for a long period and has become discharged (but still
shows a voltage reading) it can be brought back to full charge by cycling it several
times. To do this, charge the battery about ten hours, then use it for a few minutes but
not long enough to totally discharge it. Then charge the battery again for about ten
hours
two weeks and the battery may recover. Whether or not it does will depend on the age
of the battery and the care it has been given.

Storing Batteries

Stored batteries should be fully charged every three months during the storage period.
Storage for a long period without recharging may cause batteries to become unable to
be restored to capacity. This period will vary depending on what use the batteries have
had before storage, their depth of charge at the time of storage, and the storage
conditions.
Ensure the batteries are fully charged when storing.
