Hello,

I am trying to program my Victron Muti Plus inverter/charger and cannot seem to find any specs for the above noted battery. Charge rates, etc? Does anyone have information on these?
Thank you.
 
The batteries I have are

Motomaster 12V Eliminator Renewable Energy Deep Cycle Batteries 100 amp hour.​

They are lead acid AGM, They were purchased from Canadian Tire but are now discontinued. I can’t find any specs on these. I’m looking for things like;
* Maximum Charge Current
* Recommended Absorption and float voltages
* temperature compensation setting
* recommended charge curve.

Any help here is appreciated. Thank you
 
Is this it?

You may have to do a visual search of similar batteries to find out roughly who made it or one like it and use those specifications

There's likely nothing different about them then any other AGM. I'd Google a few other AGM batteries to get a good feel of the common settings.

From memory:

20% +/- 5% of is good rule of thumb for max charging current. EG: ~20 amps per 100 AH If they aren't getting warm you can go higher.

14.4 Bulk voltage

Absorption is the same as bulk, the only difference is that you can hold it at 14.4 v with less than 20 amps per 100 Ah.

A full battery is when you can hold at 14.4 V with less then~3 amps per 100 Ah.

Since they are a sealed battery I'd avoid floating charging (~13.3) them for long periods. IMHO, leaving them on a float charger for a year straight is hard on them.

Thank you for the info. Regarding the float charging; we often leave the battery bank connected to the solar array when we are not at the cabin. Temperatures can drop to -40c. Our thinking was that it is good to keep batteries charged using solar so as not to freeze them at low capacity. Thoughts?
