From the time of manufacture, lead acid batteries slowly "shrink" in capacity as they age because recharging doesn't completely remove all of the lead sulphate deposited on the internal plates during discharge (and they will self-discharge when not being used). This build-up of unremoved sulphate progresses throughout the life of the battery. Eventually, there is not enough plate area left exposed to the acid solution to deliver the current required (say, to start an engine)and the battery has to be replaced. I would assume your two batteries are connected in series - where the same charging current flows through both batteries, so you have a "large" capacity new battery in series with a "smaller" capacity old one. The voltage regulator will only allow charging up to a certain voltage and level off, which means what is left of the old battery capacity will be overcharged (with over-voltage) and the new battery is left undercharged and will fail much sooner due a continuous undercharged condition. Sulphation over time is minimized by maintaining a full charge on a lead-acid battery.

Measuring with Calipers - by Staff. The legs of inside calipers are curved outward at the extremities to facilitate measuring small holes, while outside caliper legs have a large curve inward to increase their capacity for large work. Firm-joint calipers are adjusted approximately by the hands and then set to the feel of the work by tapping them on a metal surface. It is a common practice when opening calipers by this means to tap the top of the joint. It is better, if possible, to tap the inside of the legs, as repeated blo
