Gas-recombinant absorbed glass mat (AGM) (non-sealed or sealed)

These speciality batteries not common on the Ghanaian market, mainly used in solar power and UPS applications

Wet maintenance free (non-sealed or sealed)

These are the most widely available batteries in Ghana,and depending on your vehicle we may recommend either the sealed or non-sealed version.

Wet low maintenance (non-sealed)

  1. Maintaining the correct electrolyte levels;
  2. Tightening loose hold-down clamps and terminals;
  3. Removing corrosion from both ends of each battery cable and both terminals;
  4. Cleaning the battery top; and
  5. Checking the alternator belt tension .

The above are normally the ONLY preventive maintenance required for a battery.


The preventive maintenance frequency is dependent upon climate and battery type, but you should perform this at least once every two months in warm weather.

Add DISTILLED water to the level indicated by the battery manufacturer… Use only mineral free water, Distilled is best as all impurities have been removed, and there is nothing left that could contaminate your cells. The plates need to be covered at all times.

Avoid OVERFILLING, especially in hot climates, because heat causes the electrolyte to expand and overflow.

Annewetey Auto Parts recommends that our customers stop by our shop at Danquah Circle Osu every two months for preventative maintenance to be done FREE of charge for the life of the battery.

MYTH: Maintenance free batteries never require maintenance.

In hot climates, water in the electrolyte is “decomposed” due to the high temperatures and normal charging of a wet maintenance free battery. Water can also be lost due to excessive charging voltage or charging currents. Non-sealed batteries are recommended in hot climates so they can be refilled with distilled water when this occurs.

MYTH: Sealed batteries will never run-down or discharge.

The sealed Gel-Cell and the AGM batteries are specialty batteries that typically cost twice as much as a premium wet cell. They store well and do not tend to sulfate quite as fast as wet cell. However they require special charging rate and charging machines.

There is a little confusion about AGM batteries because different manufactures call them different names; a couple popular ones are regulated valve and dry cell batteries. In most cases AGM batteries will give a longer life span than a wet cell battery, but will not stand up as well to hot temperatures and high discharge load.

A survey by Annewetey Auto Parts showed that most sealed batteries on the Ghanaian market are wet lead-acid batteries in sealed containers NOT Gel-Cell or AGM batteries!!

They only advantage is to prevent spillage and gassing. They will run down like any other battery if stored for too long or if there is a problem with the alternator or charging system. Sealed batteries will eventually dry out and fail if installed in the engine compartment of a vehicle. How long they take to dry out depends on operating temperatures and the frequency of use of the vehicle.

MYTH: Batteries last longer in hot climates than in cold ones.

Batteries last approximately two thirds as long in hot climates as cold ones. Heat kills batteries.

Especially sealed wet lead acid batteries in the engine compartment.

MYTH: You can test the alternator by disconnecting the battery with the engine running.

A battery as like a voltage stabilizer or filter to the pulsating DC produced by the charging system.

Disconnecting a battery while the engine is running can destroy sensitive electronic components, for example, emission computer, audio system, cell phone, alarm system, etc., or even the charging system itself.

These damages can occur because the voltage can rise to 40 volts or more. In the 1970s, removing a battery terminal was an accepted practice to test charging systems of that era. That is not the case today. Just say NO if anyone suggests this.
