Video Transcript for Tekonsha Trailer Breakaway Kit TK2023 Review

Today we are going to review Part Number TK2023. This is the Tekonsha Sealed Lead Acid Battery for the Tekonsha Sure Set Breakaway Kit. This is a sealed 12 volt, lead acid battery. It is again designed to fit the Tekonsha Sure Set Breakaway Kit. This batter has a 5 amp hour at 20 hours rating. This battery is used in a breakaway system because it needs to be able to power the trailer brakes on full for 15 minutes.

It is needed in the breakaway kit because if the trailer becomes unhooked from your tow vehicle, it will activate the breakaway system. This battery needs to be able to apply the brakes on that trailer to keep that trailer from a runaway situation. This is usually 12 volt battery rated for 5 amp hours is the normal that is used in the breakaway kits. Just to give you a few dimensions on this, you are looking at about 3 1/2 inches wide, 2 3/4 inches deep and the height on it is going to be right at about 4 inches. That should do it for the review on Part Number TK2023, the Tekonsha Sealed Lead Acid Battery for the Tekonsha Sure Set Breakaway Kit. .

Product received in timely fashion and was the correct replacement part for my existing battery. It was handled very professionally over the phone with Lexus. I would definitely do business with etrailer again. 216389

George J was very helpful in getting the product (battery) shipped out in a timely manner and exceeded expectations. It arrived as promised, in perfect condition and fit the breakaway case. The only reason I do not give an 'excellent' rating is that as of now I haven't actually put it to the test, since the trailer is parked, but anticipate it will perform as promised. 177921

Read other reviews online before purchase (all excellent) and decided to order a replacement battery for my breakaway trailer breaks. Called in my order so I could speak to a real person to ask questions. Order was delivered in about a week. Fit perfect in the breakaway kit case. All in all a very professional company. 57932

Ask the Experts about this Tekonsha Accessories and Parts
Do you have a question about this Accessories and Part?


  • If Breakaway Switch on Trailer is Left Unplugged with Battery Drain
  • If the battery you disconnected from your trailer is also the battery that powers the breakaway system then having the pin pulled on the switch won't be an issue. If you left the breakaway battery installed on the trailer then the pin being pulled will drain the battery. If the battery stays totally dead for a few months it would need to be replaced most likely. We have three replacement breakaway batteries. We have the Curt part # C52023, the Hopkins part # HM20008, and the Tekonsha...

  • Recommended Battery Size for Breakaway Brake System
  • The battery you use for a break away system needs to be able to power the trailer brakes on full for 15 minutes. A 12 volt battery rated for 5 amp hours is normally used, unless you have 3 axles each with brakes, then you would benefit more from a 9 amp hour battery. However a battery this large would not charge up through the 12 volt circuit coming through the trailer connector. The replacement batteries we carry, # HM20008 and # TK2023 are both rated for 5 amp hours. You can add...

  • Can a Breakaway Battery Be Used to Power an Interior Light
  • Yes, you can use a breakaway battery to power the interior light on your enclosed trailer. However, these batteries typically only have a 5 amp hour rating so that is something to make note of. If you were to use an LED interior light like the Optronics LED RV Interior Light with Switch part # RVILL34 then you would not have any issues as it only draws .6 amps of power. With that being said, you will not need the Tekonsha Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger...

  • Break Away System Replacement Battery Recommendation for a Circle J Horse Trailer
  • The battery that you use for a break away system needs to be able to power the trailer brakes on full for 15 minutes. A 12 volt battery rated for 5 amp hours would work but if you had 3 axles each with brakes you would benefit more from a 9 amp hour battery. Even a 12 volt car battery could be used but a battery this large would not charge up through the 12 volt circuit coming through the trailer connector. The batteries only that we carry, # HM20008 and # TK2023 are both rated for 5...

  • Correcting Dead Battery in Trailer Breakaway System
  • Chances are that your breakaway battery fully discharged during the overnight period when it was accidentally engaged. Breakaway batteries are rated to deliver 15-minutes of power in an emergency stop. You can try re-charging it with a battery charger like # CTEK56353 from CTEK. I own one of their chargers and it does a good job on my mower and motorcycle batteries. If a charge does not correct the problem then you can use Replacement Sealed Lead Acid Battery # TK2023 or Replacement...

  • Will Discharged Trailer Break Away Battery Affect Normal Trailer Brake Operation
  • The fact that your break away battery is dead will not affect normal braking function. However, should your trailer somehow became uncoupled from the tow vehicle and the pull pin for the break away system was pulled, the break away system would not operate the brakes. The # HM20008 replacement battery you mentioned would be a good replacement for a Hopkins or TAP break away system or a # TK2023 for a Tekonsha break away system.

  • How Long Should a Small Break Away Battery Last
  • Battery life is going to depend on several factors though I can tell you that 11 years is a very long time for a small break away battery such as # TK2023. If the battery is not exposed to high or low temperatures for prolonged periods and does not get any corrosion on the terminals then it can last a long time with regular charge and discharge cycles. If you are unsure of the battery's condition then an auto parts store may be able to hook it up to a battery tester to see how its doing...

  • Battery Type of the Replacement Sealed Lead Acid Battery TK2023
  • The battery part # TK2023 that you referenced is not a GSM battery. It is a standard lead acid battery.

  • Will Replacement Sealed Lead Acid Battery for Shur-Set III Breakaway Kit Fit Battery Box TK2051
  • Yes, the battery and box will work together. Replacement breakaway battery # TK2023 measures 3-1/2 inches long, 2-3/4 inches wide, and 4 inches tall. The battery box # TK2051 has internal measurements of 5-15/16 inches long, 3-1/8 inches wide, and 5-1/2 inches tall. I have linked video reviews of both products for you.

  • Hopkins Breakaway Battery Charger Output Specs and Compatibility with 12V 5aH Battery
  • The Hopkins Trailer Breakaway Kit Battery Charger # 20011 has a power output of 2.5 amps according to my tech contact at the manufacturer. It basically gives a maintenance charge to the battery. It is designed for use with the 12 volt 5 amp hour battery traditionally found on single and tandem axle trailers like # HM20008 or # TK2023. The larger battery you referenced in the video is needed on larger trailers like triple axle applications but this charger will work perfectly with the...
