Here are some good numbers for you NAIO
But AGM batteries must not be deviated from standard recharge profiles unless they have lost capacity. For normal charging and float maintenance follow th guide below...
There are a lot of different opinions about battery charging and we hope this will help clear up any confusion that our customers have. AGM batteries are still technically a lead acid battery and they charge very similar to a wet cell. Regardless of what some rumors portray, AGM batteries are not as sensitive as once believed. They often get confused with Gel Batteries, which are very sensitive to voltage and they need a special charger. Lifeline AGM batteries can also be equalized to regain capacity if need be (instructions for equalizing is listed below). We also offer very personal service if you would like to reach us by telephone should you have any further questions regarding our batteries.
Battery Charging:
Charge 1 with voltage-regulated (constant potential) charger. The following charging voltages are recommended for maximum battery life.
3 Stage Chargers
Bulk 14.2-14.4 volts
Acceptance 14.2-14.4 volts
Float 13.2-13.3 volts
2 Stage Charger
Bulk 14.2-14.4 volts
Float 13.2-13.3 volts
Single Stage Charger
Bulk 14.2-14.4 volts
Once the battery is fully charged, remove it from charger.
FLOAT 13.3 - 13.4 volts is fine except when the weather is 105F or warmer.
