I bought a spare 12v battery as varta had a great deal on 3 months ago.
It has been sat in the garage since.
I thought it was time to check/recharge as necessary so put it on the bench and connected my charger...... It took 30 seconds for the charger to show a green light.
Ahaa I said..... best give it something to do.... so , looked for some 12v accessories to run off it..... found my new windscreen washer set up with an electric pump (unfitted due to loss of dexterity in my fingers etc etc)
It ran fine but after a minute I thought, hang on, I'll burn this out!!
So..... found a spare 21w bulb and wired this up to do a bit discharge of the spare battery..... boy, did it get HOT just after a few seconds!! ? ... is this normal?. Anyway, decided it was too risky to leave it like that.
Have you gurus any suggestions as to how I can keep this spare battery in tip top condition please?
