| Zusammenfassung: | The utility model discloses a long service life combination battery which rechargeable batteries (1), (2), (3), (4) in parallel connection. Because of the connecting method, charging and discharging current of the batteries is large, electric discharge is clean and complete, all the batteries are mutually balanced, the batteries are not easy to be damaged. At the same time, a resistor and switch form three different working states. The ineffective loss of electric energy is reduced, and the service life of the combination battery is extended. The combination battery is suitable for various intercoms, radio pagers, etc. |
