Battery charging

Hi Rick and Kerrie,

I leave mine (Ctek M100) connected 24/7, Thats what it was designed for.

Cheers Wilko

p.s. the M100 is a 7amp marine charger almost the sameas the XS7000.

Gidday Rick,

when I bought my set-up - same as yours except a 120 ah agm - they just told me to charge it up once a month when its not in use for long periods. At the time I thought - once a month - I will be camping more often than that, so no worries.

Well, it didn't work out that I get camping as often as I hoped, so I now charge the battery once a month! I just put it on for about 48 hours, once a month. I've had it for about 18 months now - so far so good.

Check the charging voltage for your battery (mine is written on it) - from memory, mine prefers 14.7 volts, so I use the higher charging setting on the ctek 7000 - I think its called snowflake.

Cheers!

Hi Rick, welcome aboard to you and Kerrie.

Lead-acid batteries, including the AGM type, will self-discharge over a period of time and if left in a discharged state for an extended period will permanently harm the battery.

The best maintenance is to leave the battery connected to a float charger full time and your CTEK will do this nicely. If you prefer, the battery can be connected to the CTEK say once per few weeks and left on charge for at lest 24 hours.

I also have a 100Ah AGM and the same Ctek charger. Like Sandman says, the self-discharge is very, very low.Mine goes on the Ctek every 2-4 weeks. I have an ammeter in the Ctek leads so I know what's going on, and it takes very little charge. Leaving it hooked up is unnecessary.
