If you're wanting to save money on a battery, expect to buy them more often. Cheap generic Chinese ones anyway, like on Amazon.
The battery I've been using on my 200ES since 2015 is a Deka EXT15. AGM and 14amp.

They are sold under at least a couple other different brand names besides their own.

Regardless of the battery you need to verify operating voltage of the charging system from idle to higher RPMs, loaded and unloaded. The charging systems on these old trikes aren't the best and if cables and connections are bad it just makes it that much worse.
