6 volt battery
anybody tried a Ballistic battery on a 6 volt.
I been trying to find out from deltran and HD dealer why the new 6 volt HD wet type battery won't get up to 7.2V so the deltran battery tender can go into float monitor mode. HD dealer says that a wet type can only get to 6.3. deltran says wet or sealed can go to 7.2. case of each of them pointing at the other.
HD dealer says I should get a couple hundred dollar Ballistic and a special $80 charger.
researching interweb shows some had problem with lithium-ion and now they make lithium-iron that can use regular charger.
since I don't get to ride the old pan often I would like to be able to leave the 6V battery on a battery tender.

I can't see where the Ballistic is even available in a 6volt version???
These are general voltage ranges per cell:
Open-circuit (quiescent) at full charge: 2.10V
Open-circuit at full discharge: 1.95V
Loaded at full discharge: 1.75V
Continuous-preservation (float) charging: 2.23V for gelled electrolyte; 2.25V for AGM (absorbed glass mat) and 2.32V for flooded cells
All voltages are at 20 °C (68 °F), and must (for a 6 cell battery) be adjusted −0.0235V/°C for temperature changes.
Float voltage recommendations vary, according to the manufacturer's recommendation.
Precise float voltage (ą0.05 V) is critical to longevity; insufficient voltage (causes sulfation) is almost as detrimental as excessive voltage (causing corrosion and electrolyte loss)
Typical (daily) charging: 2.37V to 2.4V (depending on temperature and manufacturer's recommendation)
Equalization charging (for flooded lead acids): 2.5V for no more than 2.205 hours. Battery temperature must be absolutely monitored.
Gassing threshold: 2.4V

@gs34doc
so if gassing threshold is 2.4V per cell, and it's 6V so 3 cells, it should charge to 7.2V?
the max i could get it to was 6.6V with my .75amp and 1 amp charger, 72 hours and 22 hours.
@Ranger73
i had it on a batterytender 6V float charger for 72 hours and that was after being on a 1 amp charger for 22 hours. still doesn't want to go over 6.6.
and i had it on a 2 amp charger for three hours and maxed out at 6.6.
so i left it at the HD dealer who i bought it from a couple days ago and since i haven't heard from them it probably means they're having the same result.
but when i was there they did say 6.4V was normal full charge.?

All this math talk makes my head hurt....I have a H2
I pull my battery out and store it in the house.
Charge it the night before the ride and install it.
If it's shot buy another one or get a Joe Hunt magneto.
