Consumers Too Quick to Replace Batteries, Say CTEK

LONDON, UNITED KINGDOM--(Marketwire - May 27, 2011) - Drivers may be wasting money by prematurely replacing seemingly dead batteries without trying to revive them beforehand, warns designer and manufacturer of smart battery chargers, CTEK.

Batteries will naturally need replacing sooner or later but their lifespan can be considerably extended, sometimes by as much as 300 per cent, with the correct battery maintenance procedures. Furthermore, some batteries which may on the face of it appear to be dead, can be revived with the assistance of a smart battery charger.

When a battery's capacity is reduced without being correctly recharged, a chemical process called sulphation starts to occur within the internal structure of the battery. Here, sulphur separates from the lead-acid fluid and sticks to the battery's plates where it restricts, or stops, the battery from being able to perform.

However, rather than replacing the battery immediately, drivers could save money by using a CTEK smart charger and utilising its unique six stage process.

CTEK's chargers go through the following stages to charge but also to condition a battery:
  • Desulphation – The Smart charger will clean up the battery plates to ensure that the battery isn't suffering from sulphation – the biggest battery killer.

  • Bulk charging – The Smart charger delivers its maximum current and battery voltage increases to around 14.4 Volts. When complete the battery has accepted about 80% of the maximum charge available.

  • Absorption charging – a charge is delivered to the battery at a very low level of current, ensuring that the battery is charged to maximum capacity without fear of overcharging, overheating or affecting sensitive electrical equipment.

  • Analysis - the battery is tested to see if it will retain the charge or begin to self discharge. If self discharge is too high, charging will be discontinued and fault mode indicated.

  • Reconditioning Charging – This mode is used to recover deeply discharged batteries where you could expect a high level of acid stratification. A higher than usual voltage (15.8V) is used to remove acid stratification and restore the battery to peak condition.

  • Maintenance – Initially the battery will usually be maintained with a float charge but if left connected for an extended period this should ideally change to a 'pulse' maintenance mode to 'exercise' the battery if the terminal voltage drops to 95% state of charge. This keeps the battery in good condition when not in use. In this mode the charger can be connected for months at a time with total safety.

Battery charging not only extends the life of a battery but in the case of a CTEK charger, can save drivers money by reviving batteries that under normal circumstances may be unnecessarily replaced.
