I have a similar issue, battery is at 16.7 when fully charged so I needed to partially discharge it before use. Many of the programmable chargers have a discharge function ( check the current limit in this mode and then derate it, otherwise you may fry your charger). Then when you charge set the voltage max to 15V.
There is still a lot of margin, reading through the manual I found a reference to 16V as the max voltage rating.
Certainly this approach decreases the Ah capacity of your battery since you are only partially charging it but repurposing is a cost effective.

Has anyone risked a visit from Puff the Magic Dragon or should I nerd out and add a voltage limiter/ cut out circuit?
