Using GUEST Charge Pro to Charge Gelled Electrolyte Battery

I just purchased a boat that has a Guest Charge Pro Model 2611 with a date code of August 19, 1999. I know this is a 10 amp charger, and is currently charging two 12-volt batteries for a trolling motor. The batteries have gone beyond their reliable life, and I want to replace the current wet cells with gels. Will gels be ok? I know that in larger chargers, it does make a difference as they have a different maximum charging voltage than wet cells. Thanks for any help or advice. You look like a group of very knowledgeable boaters.

The compatibility of a charger for a particular battery is generally a matter of the maximum voltage which will be applied during charging. Lead-acid batteries with gelled electrolyte may benefit from a different charging voltage than conventional flooded cell lead-acid batteries.
I suggest contacting the manufacturer of the charger to discover if their product permits any adjustment in the output voltage to optimize it for use with gelled electrolyte batteries.

By the way, GUEST is now a division of MARINCO. They have literature available on-line about their products, including this:

Cap, the boat I recently purchased had an older model battery charger too. I sold it on eBay and used the money to help offset the cost of the new model Guest chargers. The new technology offers a great deal, including the ability to charge different types of batteries like gel and lead-acid. There's a user setting for each. Also, the new Guest chargers are very compact.
