Can my battery be saved?

And if the insurance finds out you disconnected the battery. Claim denied, alarm system was inoperative.

Good luck with that. But you are correct.

/touch wood my bakkie has never even been broken into as yet.
Had it now for about 7 years and been paying my premiums without skipping a beat. Doubt they'll be that anal :o
 
Probably a bit hard to steal with a "dead" battery.

Might just be what saves it.
 
@jewpacabra: Try to install one of these battery switches (~R120). If you disconnect the battery from the car when it is not in use this will prevent the burglar alarm system from draining it and prolong its life. My Sentra's batteries only last a maximum of three years if I don't drive it regularly and I need to charge it frequently when the battery goes flat.

Interesting...I've never seen something like that before.

I ended up replacing the battery, and I've since changed jobs so the car gets driven daily.
 
Sadly the commute is really the problem and then probably only doing short trips on the weekend doesn't really help it charge.

I ride a bike to work every day so my little Corsa stands outside and does nothing all day.

I'll have it hooked up to the C-Tek charger and then it starts first time, but I guarantee you if I leave it for two weekends it won't start again. And that's on a virtually brand new battery that's about six months old.

The real problem is that when you then drive it you don't really do a proper trip and all you really do in the process is bring it home with even less charge.

I thought you had a Gti?
 
I take public transport too - hardly drive. The one time I do drive I ended up nicking a pillar. :(

Claimed from insurance, and getting it repaired monday.

Anyway, it's good to run the car once a week. Moving parts need to be kept lubricated, which means keeping it running.
 
Truth About Batteries

Unfortunately, for public transport commuters, batteries do go flat over time when left in a modern vehicle.

If you can afford it, buy an intelligent charger and have it connected to the car battery when not in use.
This is best done if the car is in a secure garage though for many reasons.

5 or 7 step intelligent chargers are available today, just don't buy anything less than 10 Amp. (15Amp is the best for most batteries) Saving some cash on that charger and buying 3-5Amp will take very long to charge the battery which might not be a problem in general, but what happens if you need the car in emergency?

Disconnecting the battery is another option, but it comes with a lot of inconvenience. Modern cars don't like it, you'll have to readjust your radio stations, clock, convenience features etc.etc. not to mention that your computers will (may) forget your learned driving habits and have to start all over every time. this increases fuel consumption slightly too.
Also your car won't have the alarm working.

Another option is to take the battery out every time and charge it at home...but is really not for everyone...broken nails and such ;-))

Driving the car over the weekend is fine for keeping the car in good condition...but it doesn't do any good to the battery unless it's an out-of-town 200km+ non stop trip. Short distances going to the pub or shops will actually only further drain the capacity of the battery and it will eventually fail.

And lastly, modern alternators DO charge the battery at low RPM (around 1500 RPM is more than enough) so there is no point of overreving the poor engine in 2nd/3d gear around the block a fey times. It doesn't help a bit. What helps is TIME, the battery needs TIME to charge. So unless you can fast idle the car for 2Hrs minimum or take that long trip, use a good charger instead.
