Rechargeable compared to the one use alkaline battery.
- One use alkaline batteries initially cost less. The Lithium batteries will last a lot longer meaning less frequent purchases required. The rechargeable will give you a minimum of 500 charges. This is a huge savings per calculator. You are paying 19 times or more for one use alkaline batteries.
- By using NiMH rechargeables, you are reducing your landfill by 500 fold. It takes approximately 500 alkaline sets for each NiMH set.
