Recommend a replacement for a dead Guest battery charger

[Joe from ny]

Can anyone recommend a good replacement for my failed Guest 2611A dual battery charger? It is used to charge my two-battery bank for my Whistler Pro-2500 watt inverter. The batteries are Deka Marine Master DC27. I dont know which relevant battery spec's to quote, so here is the spec sheet from the website.

BTW, the only relevant footnote cut off from the chart was "Deduct 15% from CCA and CA rating shown to allow for double insulation (glass mat)"

Thanks

According to the Deka Deep Cycle Maintenance Sheet that flooded cell battery will go from 0% to 100% state of charge in 6 hours w/ 10A per battery, worst case.

If the plan is to upgrade to AGM batteries, then a larger charger is better, one providing 20A per battery is recommended.

Here is the Lifeline Technical Manual. This is the best document I've found for care and feeding of AGM batteries.

The Charles 5000 SP Marine Chargers are well built and I would recommend this product.
