Rechargeable Batteries 12 V Battery 12 Ah Amp Hours

If you need a battery to get your emergency light or toy car up and running again, one of the inexpensive 12V 12Ah batteries in this collection might be just what you’re looking for. It's easy to find the exact batteries that you need on eBay, and here are some of the things you should know as you pick out the right rechargeable 12V 12Ah battery for your purposes.

What are some types of rechargeable 12V batteries?

Here are a few examples of the different types of affordable 12V batteries that you'll find in this collection:

  • Lead-acid batteries: These types of batteries contain a highly acidic substance that stores electricity. They are relatively volatile.
  • AGM batteries: AGM batteries contain a special type of conductive gel. These types of batteries are not volatile, and they have relatively long life spans.
  • Li-ion batteries: Li-ion batteries use lithium ions to carry current from the positive electrode to the negative electrode in a battery.
Which brands make these batteries?

Here are some examples of the brands that make these batteries:

  • Mighty Max
  • Power-Sonic
  • Powerizer
  • APC
How long do these batteries last?

All of the batteries in this collection are rated at 12 amp hours, which means that if they have a load of 1 amp, they will last for 12 hours. However, if you increase or decrease the load on these batteries, they will last for shorter or longer periods of time. In terms of overall life span, these 12V batteries usually last about 500 charge cycles, which occurs whenever the battery is fully depleted and then recharged. If you want to make sure that your battery lasts as long as possible, never let it get under 12 volts.

How do you pick the right type of battery?

Keep in mind that some applications are only compatible with certain types of batteries. If you're planning to place your battery in an enclosed location where there won't be any air circulation, you won't want to use a lead-acid battery since these types of batteries can malfunction when they don't have adequate airflow. Certain types of charge controllers for solar panels are only compatible with AGM batteries, and you may want to select lithium-ion batteries because they are space-efficient. When in doubt, check which type of battery your application currently uses and select a direct replacement for that kind of battery.
