FAQ

Can NiMH batteries be substituted for alkaline batteries?

Usually. However some devices are specifically marked. Check inside the battery compartment of your device or your user manual to make sure they are compatible. Note the discharge curve of alkaline batteries continuously reduces voltage capacity. In fact, over the course of their discharge, alkaline batteries actually average about 1.2 volts. The main difference is that an alkaline battery starts at 1.5 volts and gradually drops to less than 1.0 volts. NiMH batteries stay at about 1.2 volts for almost 80% of their discharge cycle. Once alkaline batteries discharge to 50% capacity, it will be delivering a lower voltage than a NiMH battery.


How many times can a rechargeable battery be recharged?

The number of times a battery can be recharged depends on many factors. These include the discharging drain load, the frequency of use, the length of time in a discharged state, charge temperature and conditioning. Rechargeable batteries do NOT last forever and need to be replaced at some time. However, you should expect many years and hundreds of charge cycles of good performance.


If the milliAmp hours (mAh) of my current battery are rated differently than the mAh of the battery, will it still work in my device?

Yes, it will work. The mAh is a measurement to compare run times. For example, a battery with a 2500mAh rating would last 2x longer than a battery with a 1250mAh rating.
