This is why I'm not a fan of Gel batteries. When they go, they go suddenly. And there is no way to keep a check on the status of individual cells. At least a slosh, lead-acid battery usually gives warning when it it about to expire and the state of each cell can be easily checked with a readily-available hydrometer. Typically when the battery is nearing the end of it's service life one or more cells will start to show less charge than the others.

A good battery and an on-board voltmeter make for confident travelling.
