The original SLA battery in my Clore JNC660 jump starter has died prematurely after only 2 1/4 years. I never had to jump my vehicle, and I did keep the battery charged. The battery sinks to 5.0 VDC with only a 80A load on it. The Clore spec is 9.5 VDC minimum with a 100A load for 6 seconds.
I checked at the Clore website about a new battery, and they want $165 plus shipping, which is ridiculous. A new JNC660 jump starter is $130 at Amazon, $35 less than a replacement battery. A stupid pricing policy from Clore!
I measured (with a carbon pile tester and Fluke clamp meter ) the original battery when new, and it could supply a max of 385A. It was rated by Clore as 425 cranking amps.
I checked for replacement batteries on Amazon and Google, and saw a lot of mediocre choices. Only one, the $45 Mighty Max ML22-12 at Amazon, provided a specification of maximum current, which was 300A.
Are there any quality 22AH SLA battery brands that can provide 375A-400A for under $60? If not, I will give the Mighty Max a try.
