1. Compared to the one use battery. eg Duracells
    1. Money: One use batteries initially cost slightly less than the rechargeables to buy. The rechargeables will give you a minimum of 25 charges. This is a huge savings per calculator. You are paying approximately 19 times more for one use. See our calculations below.
    2. Environmental: By using Alkaline Rechargeables, you are reducing your landfill by 25 fold. It takes approximately 25 one use sets for each Alkaline set.
    3. Typical Misconception: The big complaint about the Alkaline rechargeables is the pain of charging, keeping track of when to charge and leakage. With the Calculator Charging Station, Charging Schedule, and performance warranty, that's no longer an issue.
  2. Compared to the Nickel Cadmium (NiCad) battery.
    1. Alkaline do not have any environmentally harmful chemicals & can be thrown in the garbage while NiCad have Nickel and Cadmium so they require special disposal.
    2. Alkaline are for low drain use like in a calculator while NiCad are for high drain use such as for toys, tools etc.
    3. Alkaline do not drain while stored where as NiCads drain even while sitting around.
    4. Alkaline come fully charged and ready to use, while NiCads need to be charged before use.
    5. Alkaline have no 'memory' and can be charged when partially empty while NiCads have a 'memory' and need to be fully drained before charging.
  3. Compared to the Nickel Metal Hydride (NMH) battery.
    1. Alkaline can be thrown in the garbage while NMH have Nickel & other heavy metals and require special disposal.
    2. Alkaline are for low drain use like in a calculator while NMH are for high drain use such as toys, tools etc.
    3. Alkaline do not drain while stored where as NMH drain even while sitting around.
    4. Alkaline come fully charged and ready to use, while NMH need to be charged before use.
