I know this thread is already for quite some time. just looking for existing thread to ask about maintenance free battery (so called dry cell battery).
recently i see in facebook a mechanic share that maintenance free battery actually has the water inside. just peel off the sticker on top, use coin to open the + cap, and refill the water inside. this will make battery last longer, some said up to 4 years.
i know the part that even maintenance free battery has water inside, but topping it up, never think of doing it. so what the difference between maintenance free and not? is it just simply maintenance free one use better electrodes/material inside?
please share your experience/thoughts. thanks...
