<p>A battery cycle counter (48) comprises a rechargeable battery (12) having supply (34 and 36) and charger (30 and 32) contacts, a circuit (14) for providing an input signal when the rechargeable battery (12) is being charged, and a counter (48) powered by the battery (12) and responsive to the input signal which increments a cycle count. The counter (48) has input and output ports. An analog output circuit (44 and 46) coupled to the counter output ports provides a unique analog output signal indicative of said cycle count. This counter allows a user to accurately determine how many times the battery has been cycled. A low cost and reliable battery cycle counter has been lacking in the market.</p> |
