Tekonsha 2023 12V Breakaway Battery | Sealed Lead Acid
Tekonsha 2023 12V Breakaway Battery | Sealed Lead Acid — Product description
The Tekonsha 2023 is the 12V sealed lead acid battery that sits at the heart of your trailer breakaway system. If your trailer ever comes off the ball while you're rolling, this is the battery that powers the brakes and brings it to a stop. It's a direct replacement when your old one won't hold a charge anymore.
The Tekonsha 2023 is a 12-volt sealed lead acid battery built for one job: keeping your trailer breakaway system ready to work. Every trailer with electric brakes over a certain weight is supposed to have one of these, and most boaters towing a decent-sized rig already know that. This is the small battery that lives in the breakaway box up near the coupler, waiting for the day you hope never comes.
Here's how it earns its keep. If your trailer ever separates from the hitch while you're moving, a pin pulls out of the breakaway switch and closes the circuit. That sends this battery's 12 volts straight to the trailer's electric brakes and locks them up, so a runaway trailer stops instead of rolling into traffic. The tow vehicle's charge line keeps the battery topped off through the 7-way connector while you drive, so under normal use it stays ready on its own.
Sealed lead acid is the right chemistry for this. It's maintenance-free, it holds a charge sitting idle between trips, and it doesn't need topping off with water like an old flooded cell. But no battery lasts forever. A breakaway battery that sits through hot summers and cold winters will eventually lose its ability to hold a charge, and a dead one won't do a thing in an emergency. That's exactly what the 2023 replaces.
How do you know yours is done? If the test light on your breakaway switch is dim or dead, or the battery is several years old, don't gamble on it. Swap it. Wiring is simple, two leads into the breakaway switch box, and you're back in service. We'd rather sell you a fresh battery now than have you find out the hard way that the old one quit. Check it at the start of every towing season, right alongside your lights and your bearings.

Frequently asked questions
Does a trailer breakaway switch need its own battery?
Yes. The breakaway system has to work even when the trailer is completely disconnected from the tow vehicle, so it can't rely on the truck's power. This dedicated 12V battery is what fires the brakes if the trailer comes loose.
How does the trailer breakaway battery charge?
It charges off your tow vehicle while you drive, through the charge circuit in the 7-way connector. Under normal towing it stays topped off on its own. If you tow with a connector that doesn't carry that circuit, you'll need to charge it separately.
How long does a breakaway battery last?
A few years, give or take, depending on heat, cold, and how often the trailer sits. Sealed lead acid loses capacity over time, so most folks replace it every couple of seasons or when the test light goes dim.
How do I wire it in?
Two leads run into the breakaway switch box, positive and negative to the switch. It's a simple hookup. If you're replacing an old battery, just match the connections you're removing.
Is a breakaway battery required?
On trailers with electric brakes above the weight your state sets, yes, a working breakaway system with a charged battery is required. Beyond the law, it's cheap insurance against a runaway trailer.
How do I know mine needs replacing?
Check the test light on the breakaway switch. If it's dim or won't light, or the battery is several years old, replace it. A breakaway battery that can't hold a charge is no good in the one moment you need it.
