Which Battery Type is best?
|
|
Lead/acid batteries are cheap and easily recycled, but they are sensitive to maltreatment and have a limited life. Weight for weight, Nickel/Cadmium gives more capacity, but it's expensive and hard to recycle, although the life is greater, which tends to compensate. NiMh is theoretically more efficient still, but these batteries can be expensive and because the capacity is measured at the more generous 5-Hour rate, the advantage is not what it appears to be. Our experience is that NiMH offers very little, if any, improvement in range. |
