Lead acid AGM charging help needed.

[Matt Fidler]

Hi,
I am taking my tank to its first display tomorrow and want to know if I can charge the battery tonight or is it best to get up early and do it in the morning? Not sure how they hold their charge overnight.

[Adrian Harris]

As long as the tank is switched off they should hold their charge for weeks.

I normally charge the night before.

Adrian.

Thanks Adrian

I think a more interesting question may be which charging system is used. An automatic AGM charger will stop charging when the battery is fully charged; no problem for overnight charging. A simple constant current charger has to be removed when the battery is fully charged to avoid overcharging and damaging the battery.

A fully charged AGM battery may be stored for more than 6 months without recharging. In the first month it can be used without a significant lack of charge. Each AGM battery should only be discharged to 50 % of its capacity (50 % DoD) to avoid untimely wear.

If the battery is lead-acid. It is best slow charged

Well, this charger is an automatic type, which stops charging when the battery is fully charged. There is no reason for NOT charging overnight.
