How to Choose a Rechargeable 12 Volt Lead-Acid Battery

Rechargeable battery technology has come a long way since the early days. One area where this has become obvious is in car batteries, which have developed almost as far as the vehicles themselves. Some electric cars use Lithium or NiMH chemistry for power, while others rely on standard cells.

What Kinds of Rechargeable Batteries are There?

Duracell makes are several different kinds of battery, from alkaline and NiMH AA batteries up to and including the three standard types of 12V lead-acid rechargeable batteries. Every battery comes in standard sizes, from AAA and smaller up to the much larger vehicle units. Each car battery is based around the same basic chemistry and offers a nominal 12 Volts although most 12V batteries actually provide a slightly higher voltage than listed.

  • Flooded Batteries: These are the original rechargeable batteries, with lead plates suspended in an acid electrolyte. They are relatively simple to make and readily available, but they cannot store in any position except upright.
  • Gel Batteries: Gel batteries suspend the electrolyte in a silica gel. They have the high temperature performance and the longest life of all three types.
  • Absorbent Glass Mat Batteries: This rechargeable battery design suspends the electrolyte in a fiberglass mat. It offers excellent low temperature operation and has a very low-self-discharge.

What About Battery Usage?

While most people only think about 12V lead-acid batteries in terms of vehicles, they also very commonly appear in battery backups and to provide power for motorhomes and trailers. While both usage patterns take advantage of the battery's ability to hold large amounts of power, they are sufficiently different that the 12V Duracell rechargeable battery you want for one use is not going to do as well in the other situation:

  • Starting Batteries: This the kind found in most cars. They feature thin plates so that they can deliver power in short bursts. Do not discharge these rechargeable batteries as they are not designed for it. They need full recharging in order to prevent sulfation.
  • Deep-Cycle Batteries: Most commonly for power storage, these are common in marine and RV applications. They can deliver more power over longer periods of time and have a longer lifespan when discharged. AGM batteries often appear in these kinds of applications.

Maintaining 12-Volt Batteries

The way to maintain rechargeable batteries is to use them. Like some AA batteries, automotive and marine batteries often come pre-charged, so you don't have to worry about charging them before first use. While AGM designs can hold a charge longer, all lead-acid 12V batteries are prone to self-discharge unless kept on a charger when not in use. Even as little as a day without use can damage some batteries, so always maintain a trickle current. Note that gel batteries, and to a lesser extent AGM designs, are very particular about charging so you should always check the charger for compatibility before using it. Do not store rechargeable batteries in high temperatures as that can damage them. The rules are very different for non-rechargeable batteries, as well as the other battery chemistries. NiMH batteries can't use a float current and require a special NiMH charger that detects charge levels with temperature.
