BATTERY FACT UPDATE #3 #battery #charging #overcharge #warrnambool #portfairy BATTERY MAINTENANCE Does overcharging damage batteries? ANSWER: OVERCHARGING is the most destructive element in battery service. Usually the boater is not aware that this is occurring as he believes his alternator or battery charger is "automatic." Unfortunately, these automatic circuits are sensitive to voltage surges, heat, direct lightening strikes and indirect lightening electromagnetic influences and could fail or shift their calibration. When they fail, overcharging begins to effect the batteries. During overcharging, excessive current causes the oxides on the plates of the battery to "shed" and precipitate to the bottom of the cell and also heat the battery, thus removing water from the electrolyte. Once removed, this material (which represents capacity) is no longer active in the battery. In addition, the loss of water from the electrolyte may expose portions of the plates and cause the exposed areas to oxidize and become inactive, thus reducing additional capacity. Sealed batteries are not immune from the same internal results when overcharged. In fact, sealed recombination absorption and gel batteries are particularly sensitive to overcharging. Once moisture is removed from the battery, it cannot be replaced. Portions of the battery damaged due to overcharging are irretrievable. However, if detected early, corrective adjustments to the charging device will save the undamaged portion of the battery. Initial signs of overcharging are excessive usage of water in the battery, continuously warm batteries, or higher than normal battery voltages while under the influence of the charger. If overcharging is suspected, correct immediately.

BATTERY FACT UPDATE #2 #DEEP #CYCLE #BATTERIES #batteryworld #warrnambool #portfairy What is the difference between deep cycle batteries and starting batteries? ANSWER: Unfortunately, the term Deep Cycle has been overused by the battery industry as a sales tool to imply a heavy duty product. This has led to confusion and difficulty in battery selection. One must understand that any battery may be termed deep cycle as all batteries may be fully discharged and charged. However, a true deep cycle battery, such as Rolls or Lifeline, is capable of thousands of these hard cycles during its life without losing its capacity. Comparatively, many advertised deep cycle batteries composed of thin plates, excessively porous separators, and low density plate oxides will suffer permanent capacity loss after a few dozen cycles and will shortly sulfate or shed plate material and fail. Batteries without substantial materials designed for true deep-cycling will lose more than half of their capacity after only a few cycles. A 200 Amp-hour battery will shortly become a 100 Amp-hour battery for the remainder of its shortened service life. What initially may seem to be an inexpensive battery to purchase, now costs twice as much per Amp-hour. True Deep cycle batteries will perform well as cranking batteries, however, cranking batteries will not survive deep cycle use. Deep cycle batteries can be used in any application and exhibit a long service life, while cranking batteries are limited to starting applications only. Cranking batteries exhibit poor service life in cycling applications.

Fact update #1 BATTERY RATINGS How are batteries rated and what do the ratings mean in battery selection? ANSWER: The most common battery rating is the AMP-HOUR RATING. This is a unit of measurement for battery capacity, obtained by multiplying a current flow in amperes by the time in hours of discharge. (Example: A battery which delivers 5 amperes for 20 hours delivers 5 amperes times 20 hours, or 100 ampere-hours.) Manufacturers use different discharge periods to yield an different Amp-Hr. Rating for the same capacity batteries, therefore, the Amp-Hr. Rating has little significance unless qualified by the number of hours the battery is discharged. For this reason Amp-Hour Ratings are only a general method of evaluating a battery's capacity for selection purposes. The quality of internal components and technical construction within the battery will generate different desired characteristics without effecting its Amp-Hour Rating. For instance, there are 150 Amp-Hour batteries that will not support an electrical load overnight and if called upon to do so repetitively, will fail early in their life. Conversely, there are 150 Amp-Hour batteries that will operate an electrical load for several days before needing recharging and will do so for years. The following ratings must be examined in order to evaluate and select the proper battery for a specific application: COLD CRANKING AMPERAGE and RESERVE CAPACITY are ratings used by the industry to simplify battery selection.
