whats a decent car battery for infrequent starts?

Postby wagonrunner » June 11th, 2020, 4:43 pm

Looking for a decent battery for a vehicle that is not run everyday.
Got in habit of disconnecting battery every night it is parked.
Stock engine, no amps, rewired starter.
Any suggestions?

Tried two track NS60's and they cannot do it. would not recommend.
the 1st batter was installed May 2018.
battery indicator is never green, and they always say the battery is good with some excuse why the indicator is not green
But the car passes their checks, and alternator supplies charging voltage 14.2-13.8
The 2nd battery is doign the same as the first. (drops 0.4V overnight while disconnected.) and will not start the vehicle even if it reports 12.2 volts after reconnecting. and indicator is never green).

The 2nd battery was loaned me a week in early May 2019, while they checked the orginal.
The 2nd battery has a sticker on it saying it was activated in July 2019 when it was installed in the car.

There is none but your most reliable fixes may be an Optima battery or a battery conditioner.

A lead-acid battery is designed to be charged to capacity and stay charged for maximum life. Disconnecting serves to reduce the discharge current but self-discharge is not eliminated.

Some people choose to use a larger battery. Some choose to use a deep cycle battery. Better built batteries with tighter chemical tolerances and denser plates also help.

Most vehicle specifications require that a battery start a car that has been parked at -15°C for 30 days. That is not a worst case scenario.

At locations in the Arctic, fleet vehicles typically use an engine block heater and a battery conditioner to aid in start reliability.

Unfortunately, the enemy of lead-acid batteries in the tropics is that the temperature never gets cold enough to stop the chemical processes that calcify and leach the lead plates thereby causing failure.

if AC power is available where the vehicle is parked,just get a cheap-o battery tender, problem solved
