Aiming at the current maintenance of the lead-acid batteries on CDMA bases, this paper analyses the main reasons for the failure of the lead-acid batteries, puts forward the equipment for detecting the parameters of batteries and restoring the defective one, and develops the remote control platform to realize the simultaneous motoring of the battery working states on the base. With the data analysis, the automatic control can be achieved to charge, discharge and restore the batteries. The scientific and reasonable charge and discharge control can improve effectively the lead-acid battery working life and the maintenance efficiency of the spare batteries on the base, hence reducing the maintenance cost.
