When selecting a lead acid battery its recommended that you purchase a battery with the greatest reserve capacity or amp hour rating possible. The physical size, cable hook up and terminal type should also be taken into consideration.
Be sure to purchase the correct type of battery for the job it must do. Remember an engine starting battery and deep cycle batteries are different. ‘Freshness’ of a new battery is also very important as the longer a battery sits and is not re-charged the more damaging sulfation build up on the internal plates.
Remember to check the date of the battery. Most batteries have a date of manufacture code on them. The month is indicated by a letter ‘A’ being January and a number ‘4’ being 2004. C4 would tell us the battery was manufactured in March 2004. Remember the fresher the better. The letter “i” is not used because it can be confused with #1.
