Largely, It is a functin of OAT. Higher OAT and residual engine heat will exacerbate the rate of evap. It seemed to me the OEM battery required adding distilled water more often; the Walmart replacement not as often. What is not 'constant' is the conditions where the battery spent its life (as I have moved 3 times during the battery life and have rode in places with extreme temp shifts. = -40(cold storage) to +117F. yeah, that is hot. rev's rule of thumb. at a mininimum: Check the water level everytime you change the oil. If riding in temps above 90 and certainly above 100F, you should check more often. Higher temps, I check every 1000 miles. When the battery is new, I index the min/max lines on the battery with a 'sharpie' all the way around it so I can easily see the levels. I went 5K last summer and never added any water to one KLR. Two years ago, 2 KLR's rode 2427miles in 12 days no water added before, during or after the trip. Temps on several days above 105F. Fluid levels are absolutely necessary on a lead acid battery for battery longivity. The last three lead acid batteries I changed in the KLR's ALL lasted 4.5 years. Everyone of them. The last KLR I bought had a two year old batery w/low fluid on inital inspection and 'low and behold' it failed almost immediatly which I would attribute to poor PO maint. shrug. Don't taze me man-- yeah, yeah, yeah, if it is glass mat, etal, you don't have to check fluids. However: You will also be like the recent poster: started good, started good, started slow, then battery FAIL. shrug. Just know your limitations. smile. check the battery voltage once a month after 2 years to give you peace of mind about your battery health. Full charge = 12.6V+ (2.1v/cell) Anything less and your battery is telling you it needs a top off or if it is old, it is going 'South' sooon. revmaaatin.> > If we assume the bike is charging the battery at the right level, and the battery cells are filled to the top, how many miles/km should I be able to go before the battery reaches the lower fill level? > > Thanks > > > Crash >
