Hi there… For those who might want to see the basic question - I’m looking for advice on how to maintain a spare battery for jump-starting my car for a couple weeks. Seems I’m guna have to jump it almost every time I start it. Mechanics here are closed til April so I have to get myself through till then. I bought a spare battery for this today and I know I can’t use it over and over without recharging… figure I’ll have to keep it connected to my car battery after jumping it, to recharge. My question is - do I do this every time I use it? How many minutes should I keep it connected? How long can the battery sit unused before losing charge? And do you have any other safety or maintenance tips for this method of starting a car? If it matters, I’m here in Malaysia where our batteries are still the old kind with four screws you open to add battery water. I drive a 1999 Proton Saga Iswara.
Found some notes on this on Quora… that it might be dangerous to carry on the car, especially if it gets toppled over, acid can leak out. Maybe i should just keep the battery at my house in case i need a jump when I’m alone, then depend on other people if I’m in town.
Okay, if background helps - I started having odd behavior from the car starting a couple weeks ago… delayed response for electrics to show life after I turn the key to accessories, clock would reset to 1:00 when I tried to start it, sometimes it would just clickclickclick. Took it to the mechanic and they jiggled some wires and ran some tests, said the battery’s fine, didn’t charge a dime - love those guys - said to come back if it kept acting up, and I’ve been meaning to go back cus it was still acting up, but I’ve been so busy and here I am… Just last night it did more than act up, it refused to start. We had to pop the clutch… reminded me of college. Anyway so go figure country’s on lockdown starting today for Covid, and for some crazy reason they think mechanics are a non-essential service. So I went by a mechanic and just called through the gate (it’s their house, most mechanics here have their garage at their house) and I bought a spare battery to jump it for now, since that’s what my mechanic always does. I asked them a lot of questions but my Malay just isn’t that good, so I thought I’d look online for tips… but there’s surprisingly little advice about this online. In a couple weeks the mechanic will open again and we can find the underlying problem. For now I just need this spare battery to get me through the next couple weeks. Any advice will be appreciated. Stay safe everyone.
