Plus, you may have to pay for your medication which can cost $8 or $9 for one 8 mg. strip or pill. If you take more than one strip or pill a day and have no insurance coverage, that could add up to a lot. For example, two 8 mg. strips a day for a month at $8 would cost $480. If your insurance does pay for the medication, they may required counseling twice a month which could add to your cost.
Sealed AGM batteries typically last 3 to 5 years on average. 6 to 8 years is easily obtainable with proper maintenance. Typically sealed AGM batteries will give warning before completely dying. They will start slower, and require more charging. This is your clue to replace the battery. Typically they do not fail all of a sudden. Conventional acid-filled batteries have a harder life, for many of the reasons listed above. Conventional batteries typically only last 2 to 3 years on average. Although, 4 to 5 years is possible, in the best environments, and with excellent maintenance.
If you do believe these claims and do the math, the conventional battery should only have a warranty for 12/5-year or 2 months and 12 days. Yet a flooded cell battery of comparable price has a warranty for seven years. This does not make sense. Someone is deluding themselves.As I have mentioned previously, at work I have $20,000 worth of AGM batteries in service (80 jars at $250 each) and we can barely get four years of useful life from them.
