After 5 years and 5 months of flawless performance, battery is starting get slightly sluggish but only only after not starting for a few days, and only when I haven't been connecting my battery maintainer. Going to replace it now rather than push my luck. Getting the same model number D34-78. I keep a quality maintainer connected most of the time when Jeep is not in use.
What kind of vehicle do you drive? 1985 Jeep CJ7
