Deka Sports Power ETX-30L

Best long life battery on the market! I have purchased 4 of these Deka batteries, they last 4-6 years, problem free. I highly recommend them & the vendor, shipped immediately, received within 4 days of my order. Thank you!

Battery fits perfect in my motorcycle. It has sufficient power to crank the engine.

Is working well

Only Heavy Duty MotorcycleBattery that lasts for years of daily driving.

Battery was bad and would not hold a charge. Company made it very difficult to return and would not replace or issue refund. $165 lost.

It was as described

I bought this great battery in 2015. It lasted me six years it cost me just over $100. I was so pleased with it that I purchase it again in February 2021. I paid more, but I knew I would get a great battery. Today it died and has an internal error. I use this battery often in my Polaris Ranger and I also keep the battery topped up with a low-voltage charger whenever I feel that it needs it. So I got a little under 2 years for a battery that in the past was great. And now that same battery is $60 more. The warranty is only one year and so I think I’ll look elsewhere next time. Too much money to be paid for a battery that keeps going up in price but only last under two years.Update: I was able to charge the battery with a trickle charger and bring it back to life. I believe some of these battery chargers show an internal error when the battery is low. It is taking a charge now and I have changed my rating. I will update if the charge does not hold, but for now I am glad I don't have to buy a new one.

This fit my '14 Ultra Limited perfectly. I replaced a 5 year old HD OEM battery. It took longer to unbolt and remove everything on top of the battery than actually installing the battery in the bike. I put it on a trickle charger prior to installing. Cheaper than a factory Harley battery and it handles all the accessories (heated grips/seat, LED lights and stereo) with no issues. The battery cranked over immediately with zero issues. It's at least comparable to the factory battery but I can't say for certain if it's better. Time will tell the life of the battery but I'd definitely buy again.
