    Default Battery life

    After a cold winter here in Sutherland the battery in my Terios is again kaput. It is a small 35a/h battery (616). I considered fitting a higher output battery, but due to limited space decided against it. My question is the following: how can I extend the battery life? We use the car once or twice a month to drive the 32km into town. Maybe a longer trip to Worcester or Cape Town twice a year. What will be the better option:

    - Disconnect the battery and only reconnect when needed.
    - Start the car at least once a week and let it idle for a few minutes.

    Any other suggestions?

    Thanks,

    Martin

    Permanently connect it to an intelligent trickle charger. Benson or similar. Midas or Autozone will have some examples.

    Hi Martin.

    My advice would be to get a good "smart" battery charger and to fully charge your battery once a week.

    Agree with Jelo, I do that for my Patrol which is a Safari vehicle only, so does not get used often, I do it on the starting and dual battery system (3 batteries in totals 1 x 85ah, 2 x 105ah). For this I use a 5amp CTek intelligent charger.

    When my mother-in-law died, I bought her spotless 1984 Corolla 1600 GLX (with less than 200k on the clock) for R10,000 from the estate. This car I use maybe once in 3 months, so I have a small 0.8amp CTek intelligent charger to keep its 616 battery alive.

    Both work well for the correct size battery. Both are connected permanently when the vehicles are not in use.

    A better battery last longer. I installed a 2 year warranty battery for my daughter's swift which she used to drive 2 km for a weekend only when at university, and after 5 years to battery is still there. No charging, nothing in between.

    Better quality batteries are recommended.
    In my BMW my Genuine battery lasted 7 years, I recently replaced it with another BMW one. Not because it died, its just that I am worried it will soon.
    My FIL Volvo is still on original 2010 battery, it doesn't get used much nor its connected to any chargers.
    I recommend some good quality chargers, but invest a bit more in a good quality battery.

    I bought a Bosch battery, will see how long it lasts. We are not spoilt with choices here in Sutherland, our Co-op only stocks Bosch batteries.

    I prefer a fixed voltage power supply, set to about 13.5V. An intelligent charger can cook a battery if the battery is not 100% causing the intelligent charger to be on the wrong stage instead of staying on the last trickle charge stage. It's unlikely, but happened to me.

    At 13.5/13.6V it's unlikely that you will cook your battery, and it will keep them fully charged. Plus, these power supplies are cheaper than intelligent chargers - I use MeanWell for this.
