Power Source - Seiko S833 Instructions Manual

The battery used in this watch is a special secondary battery, which is totally
different from ordinary silver oxide batteries.
Unlike other disposable batteries such as dry-cell batteries or button cells, this
secondary battery can be used over and over again by repeating the cycles of
discharging and recharging.
However, for various reasons such as long-term use or usage conditions, the capacity
or recharging efficiency of the secondary battery may gradually deteriorate. Worn or
contaminated mechanical parts or degraded oils may also shorten recharging cycles.
If the efficiency of the secondary battery decreases, have the watch repaired.
■ Remarks on replacing the secondary battery
・ Do not remove the secondary battery yourself.
・ R eplacement of the secondary battery requires professional knowledge
and skill. Please ask the retailer from whom the watch was purchased
for repair.
・ I nstallation of an ordinary silver oxide battery can generate heat that
can cause bursting or ignition.
