Deka Power Sports ETX20L Battery

The Deka battery fit like a glove in my 08 Harley Davidson FXSTC. It is the exact same dimensions as the Harley Battery and has the same specifications but at about $60 less. In doing my research, Deka makes batteries for many "companies" who put their logo on them. My previous battery was 6 years old and probably lost a cell. With this battery the bike did not hesitate to fire up.Shipping was fast and when I put the Deka on the 3 AMP Battery Tender, it read over 80% charge and was topped off in about half an hour. I will update this review as the summer goes on but I am confident that this will do the job well.

Why did you pick this product vs others?:Fits and works

The ETX20L fit my '94 Heritage Classic exactly, and worked perfectly right out of the box. There was no need to add acid or put it on the charger at all; I opened the box, installed the battery, and was off riding in 20 minutes. Good bye to that click, click, click from the old dead battery, I’m back in the wind baby!

Good battery 2nd one in 5 years

It has been 7 months so far and the battery has been great through the summer heat and winter cold in a 4 wheeler. I do disconnect the terminal if I'm not going to be using it for a while. Good value.

Perfect fit for my HD. Plenty of starting power (310 CCA).

Very disappointed with this purchase. I bought this battery in June of 2023 and by February of 2024 it was completely dead despite being on a Battery Tender through most of the winter, and indoors. I admit I should have contacted their customer service immediately when I noticed the unit wasn't charging, but unfortunately time got away from me and by the time I was able to contact them it was a couple weeks past the warranty period. Consequently they would not honor the warranty. Understandable, my fault for not contacting them sooner, but I'm disappointed that this US made product wasn't better quality. The customer service was difficult to contact as they do not sell directly through Amazon. The battery I bought was from a third party and it likely sat on their shelf for months or years before I bought it. I will say that once I was able to contact them they were friendly and courteous. Won't buy it again though.

I found I ran this battery down fairly quick. To be honest I put it in a bike that needed a lot of trouble shooting to start I bought used. When the battery got weak I put a heavy charge into it and drained it again repeating 1/2 dozen times. I put it on a slow 2amp charge over night several times. Now that I do have the bike running the battery is the weak link. Maybe I beat the little guy up too much. The price is right however if you are going to abuse it might want something a bit more durable
