Frequently Asked Questions

How long do sealed lead acid batteries last?

Sealed lead acid batteries are used in tens of thousands of devices. I couldn't answer the question for every device. However, I can answer it in general terms. It all comes down to energy output and design life. Most electronic devices use a battery as a backup device. That is, it is only there for when the power goes out. In that circumstance, the batteries are rarely used, so you should expect 3-5 years of life out of it. For example, your home alarm system has a battery in it to keep your alarm working when the power is out. Out of 365 days, your power is probably out maybe two days a year. So the battery is only being used those two days. The rest of the time its being trickle charged. Because charging a battery causes heat, after years of exposure to steady currents of electricity, the battery will have simply "dried up". Its electrolyte will have evaporated off leaving the battery unable to receive a charge or store the energy. In the case of a device that's main supply of power is batteries, the batteries will wear out much faster. If you are using the battery on a daily basis, it will probably only last a year at the most. Sealed lead acid batteries can only be charged and discharged 300 times at the most, unless you have a pure lead battery with a high input/output rating. Enersys makes some Cyclon batteries that will last longer.

What is "reverse polarity"?

Reverse polarity is when the positive and negative contacts on a battery or device are reversed.

What do I do with my old batteries?

You can dispose of any batteries at any RBRC affiliated store. The RBRC (Rechargeable Battery Recycling Corporation) has members in every major city in the United States. There is no charge to drop your batteries off there. Home Depot and Radio Shack are two of its predominant members.
