LUCAS car batteries need less maintenance
Some battery companies offer inferior products and claim that their batteries are MF (maintenance free) when there not. An MF battery will be sealed with a flat top and have no sign of filler caps on top of the batteries at all, they will have a flat top. The star tops are usually cheap batteries.
The cheap batteries will use up a large percentage of its liquid in the battery, due to the constant charging and dis-charging together with the heat from the engine which almost boils the acid and causes evaporation , with the loss of liquid and the need to top the battery up with “distilled water” just like in the old days you will be constantly topping up your battery, especially in hot weather.
The liquid that is in your battery is a diluted mixture of sulphuric acid and water known as electrolyte. The process turns into a gas mixture of oxygen and hydrogen and escapes from the battery, thus you will have to top the battery up at regular intervals.
MF car batteries are a much cleaner battery to buy
In a conventional battery,(This is usually recognised by having accessible screw tops on each cell) we then add “distilled”water to keep the battery topped up to the correct level.
Maintenance free Known as MF batteries such as Pennine King Power batteries and Lucas batteries and Tungstone batteries all use a different type of lead alloy in the make up of the cells, made of a calcium lead
alloy known as calcium/calcium(C/C). MF batteries also use calcium alloy of lead and not a lead antimony alloy as in the cheap batteries. This reduces the gassing as in normal lead batteries. The fact that there is no water loss allows the battery to be sealed thus eliminating the need to have to top your battery up, a great benefit. You do not need to top the battery up ,once fitted the battery will never require any maintenance, thus it is an MF battery.
