Adding another battery

[richardtan]

Dear friends,

I am a newbie and need some advice on installing (adding) a 2nd car battery.

I read that a Split Charging Relay can achieve this.

However, I do not know if this device can charge a second 12v lead battery that is lower in amp-hour capacity ?:hmmmm:

Is this Relay a must? Will the alternator really be destroyed if this is not used?

Hope to hear your comments.

Thanks.

best regards
Richard
