Absolutly not necessary. The battery will go a long time, months, of average use, on a charge. You are alerted ahead of time when the battery is low. Even if it goes dead you can charge if for a couple of minutes and it will be good for 30-50 button pushes.
IF you recharge the battery once a month it will still recharge to 85% of its original capacity after about 300 charges (about 25 years). It can be recharged about 1000 times before not being able to hold a charge.
Under what we consider normal usage the battery should need to be recharged every 2.5 - 3 months. At this recharge level the battery should maintain full charging capacity for over 7 years.
- After 300 recharge cycles, the battery pack will charge to approximately 85% of its original capacity.
- After 500 recharge cycles, the battery pack will charge to approximately 70% of its original capacity.
From the GS Admin Guide:
The low battery notification returns after you dismiss other notifications, and is not displayed while the system is in a call.
