Have a supercharge gold n70 under the bonnet and two allrounders in the back.
The gold n70 under the bonnet is showing red "needs attention" in the little indicator window, after a 4 hour drive. Measured the voltage, read 13.0v, then settled to 12.8v. Put it on the charger, 5 stage, charged through, charger showed battery full, but the little window on the battery now shows white "needs charge", measured at 12.9v. Shook it around, window changed colour to red but not green. Cranks the engine fine. Now this is a worry as it needs to crank the winch. The two allrounders in the back are reading 12.9v and green indicators, all good. Question is, should I worry?

Some batteries do that when they need a top up .

Though as much, but its sealed except for the little indicator window which unscrews. Might add some water tomorrow and see what happens.

Time to replace the battery that means. Put it on charge for 24hrs, depending of amp rate of charger too. If it doesn't turns green, chuck it.
