There is a difference in battery life between wet, sealed, gel and lithium batteries. A wet-cell battery is a good basic battery, but has its weaknesses. One problem is that these batteries are available in a wide range of quality, and price is not always the indicator of how good the battery actually is.
These batteries fail mainly from non use, which causes permanent damage in the form of sulfation. Some better quality wet batteries have a chemical additive to help prevent this problem,but eventually the battery will be damaged. The other main problem is lack of maintenance keep the electrolytes to the proper level with distilled water.
sealed Batteries are usually high quality batteries but may have a lower amp capacity compared to wet or gel batteries.The high the amperage rating, the more cranking power you have.
Lithium & Gel Batteries are the best quality being a "maintenance free" battery, they don't suffer when ignored as badly as a wet battery. Of course you pay the price for this convenience.
The Best battery charger I have found for maintaining is a battery tender. It can be left on the battery indefinitely without damaging the battery like a trickle charger. For charging your battery use a maximum of 3 amps. High amperage chargers will damage your battery.
