Battery charger for detecting the current rate of charge for rechargeable batteries
First Claim
1. A battery charger system for providing least two different rates of charging currents to rechargeable batteries and for distinguishing which rechargeable battery of similar size batteries should get which rate of charge current, said battery charger system comprising a rechargeable battery having a positive terminal and a spaced-apart negative terminal for delivering power and having an indicator band disposed between said positive terminal and said negative terminal to indicate a preferred charge rate of current the rechargeable battery can accommodate;
- a charging device comprising current means for delivering at least two different rates of charging current; and
detection means for sensing the presence and location of the indicator band on the rechargeable battery and for directing the current means to provide a specific rate of charging current to the rechargeable battery depending on the presence and location of the indicator band on the rechargeable battery.

Abstract
The invention relates to a rechargeable battery for use in a charger device capable of delivering at least two different rates of charge current, said battery having a positive terminal and a spaced-apart negative terminal for delivering external power and receiving charging power, an indicator band disposed between the positive and negative terminals the location of which is indicative of the rate of charge that the battery can safely accommodate other than the rate of charge it could accept in the absence of the indicator band.
