Help Charging Battery

[MP_R33]

Hey guys,

As topic states I need some help with my battery. I have purchased a CTEK charger and want to begin trickle charging the battery whilst it's in the car.

I have been told not to connect the negative connection to the battery. Is this right? Do I need to connect it to the chassis or is having both the positive and the negative on the battery fine?

Thanks

Did mine lastnite with my CTEK and the Micra is hooked up Right Now!

Just connect to the battery. All good.

its a precaution for jump starting, in case there's a bit of hydrogen around the battery and you create some sparks with jumper leads.

leave your charger powered off, then hook it up to the battery, then power the charger on, it will be fine

ALWAYS loosen the cell caps when charging a battery.

A long time ago in a workshop far away.........

We had customers bring batteries in for charging. A few times a battery would have a dead cell, either the plates were warped & touching, or the envelope would be stuffed. The result....hydrogen pumping out of the dud cell!

The apprentice put a bad battery on charge once without loosening the caps, result was 1 cell was pumping a 3ft white hydrogen plume out of the small breather hole on the cap! One spark with the right ratio & BOOM!!!

ALWAYS monitor any battery on charge, don't leave them unattended for long periods!!!!!

The battery is sealed, so I'm good with that respect.
