The Facts You Need About 12-Volt Rechargeable Batteries

The 12V 9AH sealed lead acid (SLA) battery is one of the reliable rechargeable batteries on the market. These batteries, invented in 1859, are alternatives to powering quite a few vehicles and equipment. All you need is to find an appropriate battery to provide the charge time you need for your purposes is right here on eBay.

For what can you use these batteries?

These 12V 9AH batteries are for able to be used in a number of environments. The most common is for home or business alarm systems as a backup due to a power failure. Golf carts are another place where these types of batteries are often used. Other uses for these rechargeable batteries include:

  • Uninterrupted power systems (UPS)
  • Generators
  • All-terrain vehicles (ATV)
  • Various lighting equipment
What are the benefits from using an SLA battery?

There are many benefits to using these rechargeable 12V 9AH batteries. One important benefit is its value of being maintenance-free. There is no need to replace any of the contact fluids to keep the battery operational. In addition, these batteries are leak-proof and aren’t sensitive to positioning, so you can put them wherever they need to be without worry. Furthermore, these 12V, 9AH batteries come with a safety vent to help release gas in case there's an excessive buildup of pressure.

What are ampere hours (AH) for a battery?

The ampere-hours (AH) of a battery are the result of a charge from the volts. It pushes an electromagnetic force through the battery, which helps its chemicals to combine and produce power. When fully charged, each AH represents a single ampere of current flow within a one-hour period; that is not necessarily a solid 60 minutes. In some cases, these types of rechargeable batteries are not consistently run.

What is the life cycle of these 12V 9AH batteries?

There are two answers to this question, as it depends on the circumstances. Regarding the lifetime, this type of battery lasts between three and five years on average. However, that can be shortened if the battery is left in extremely hot or cold environments for a long period. On an operational basis, the battery's life depends on its power consumption. Specifically, if the battery's average consumption is 20 watts, then you would multiply the volts and AH and divide it by the number of watts. Thus, the batteries life cycle before a charge would be approximately 5.5 hours.
