Thread: lead vs lead-calcium battery in D2

Hi - I've had a HD (850 CCA) Century lead sealed battery in my D2 for a year and it seems to work fine...although I'm struggling with my Waeco on 'high battery protection' setting despite having HD cables direct from the battery...so possibly I've got just enough grunt to start the motor but the battery's still not putting out enough current to run the fridge happily at this setting (runs fine on low or medium battery protection but that's not much consolation when you've only got a single battery). Is lead-calcium critical in D2s or just desirable? The battery place I went to seemed knowledgable and looked up the Century book for the D2 (hopefully Td5!) recommendation...

All batteries have calcium in them it’s the amount that make the difference in performance for different chores.

Batteries with higher amounts of calcium are usually better for starting but do not like being cycled to low while batteries with lower amounts of calcium lend themselves better to doing what you want but in any case, it all comes back to how well they are being charged and long they get charged, as in how long you drive for and how often.

Cheers.

seconded although I have found that the calciums are real hangers...

with the slightest load on them they drop quickly from charging voltage to just under thier no load voltage then they hang on and hang on and hang on and then all of a sudden they drop faster than a lead balloon.

Standard batteries seem to have a more linier drop to them... (and by that I mean your normal starting batteries like the N70


But Ive only ever had 2 calcium batteries so my testing might not be conclusinve across the board.
