It is important for you to make certain that it is kept in tip-top condition at all times. Conducting regular battery maintenance will enhance the lifespan of your battery
A fully charged battery should read 12.75 volts (once disconnected the from charging process and after standing for about six hours )
A battery measuring 12.00 volts is discharged ( it has lost 60% of capacity ).
A battery should never be stored discharged
Always recharge a battery prior to storage.
Always a use an intelligent battery charger to re-charge a battery.
Most Intelligent chargers may be left permanently attached to a battery.
The correct charging voltage for a 12 volt vehicle’s charging system is 13.80 – 14.30 volts
Always check the vehicle charging voltage with a load on (e.g. headlights and air conditioning unit ).
Trickle charging a flat battery to recharge it is incorrect.
A flat battery should be recharged at a minimum rate of 10% of the battery’s rated ampere hour capacity. E.g. a 100 ampere hour battery should be recharged at a minimum of 10 amps, higher amperage is also acceptable so long as the process is controlled – i.e. using an intelligent battery charger.
It is advisable to give a storage battery (e.g. a caravan battery) a good shake from time to time. This keeps the electrolyte at the correct consistency and helps to eliminate stratification. (This only applies to wet acid batteries ).
Recharge your vehicle battery with an intelligent battery charger (even if it is fully charged) from time to time, especially if the vehicle only does short runs or is not used often.
The vehicle battery does not need to be disconnected when charging with an external charger.
When going away for a long time and leaving a vehicle behind, it is advisable to recharge the battery using an intelligent charger then disconnect the battery or attach an intelligent battery charger during this time.
A good quality calcium, calcium (negative and positive plate) will retain its charge for up to 12 months after being fully charged and with no load or drain on it.
Typical loads on a vehicle battery – alarm, satellite tracking, electronic computer etc.…. can drain a normal vehicle battery in three weeks.
Most common batteries are termed – LEAD ACID BATTERIES.
What differs is the composition of the electrolyte
– WET or FLOODED – normal wet acid
– AGM ( absorbent glass mat ) where the electrolyte is pumped into the battery wet, and is then absorbed into the battery separators
– GEL – the electrolyte is of a gel consistency and is pumped into the battery as such.
BEWARE – The above batteries require different charging characteristics and cannot all be charged on the same charger settings in the second phase of charging (equalisation /absorption phase ) WET / FLOODED batteries require – 15.8 – 16.00 volts AGM batteries require – 14.7 volts GEL batteries require – 14.4 volts NOTE: Once the charge cycle is complete, all battery charger voltages should not exceed 13.60 – 13.80 volts – especially if the charger is left permanently connected to the battery.
Most good quality intelligent battery chargers allow for the changing to the correct settings to recharge batteries of different technologies.
