DAV longevity tests

[Morandir835]

This test is still very much going on, it's been a true labor of love do to the charging time of the DAV and a slim line. Using 650mah DAV's for that very reason. One has been charged only on the slim line and hasn't been deep cycled at all, while the other has not only been deep cycled but am using a different charger on it that V4L doesn't sell, and the third used only with a fast charger but never deep cycled. All tests have been done using 1.5ohm dual coil cartos with voltage set at 4.8v for maximum load on the DAV.

DAV 1. Never deep cycled, only used with slim line-

Average use time after 5 charges (baseline)- 2 hours 48 minutes
Average use time after 50 charges- 2 hours 49 minutes
Average use time after 75 charges- 2 hours 47 minutes
Average use time after 100 charges- 2 hours 47 minutes
Currently on charge number 121, will be updating this after charge 150.

DAV 2. Always deep cycled, used with a fast charger never left unattended at my own risk-

Average use time after 5 charges (baseline)- 2 hours 51 minutes
Average use time after 50 charges- 2 hours 50 minutes
Average use time after 75 charges- 2 hours 44 minutes
Average use time after 100 charges- 2 hours 41 minutes
Average use time after 150 charges- 2 hours 38 minutes
Currently on charge number 173, will update at 200 charges

DAV 3. Never deep cycled, only charged with a fast charger at my own risk-

Average use time after 5 charges (baseline)- 2 hours 48 minutes
Average use time after 50 charges- 2 Hours 47 minutes
Average use time after 75 charges- 2 Hours 46 minutes
Average use time after 100 charges- 2 Hours 44 minutes
Average use time after 150 charges- 2 Hours 42 minutes
Currently on charge number 179, will update after 200 charges

What the early results show thus far are (not surprising on either) is running it down to the blink has reduced capacity, as has using the fast charger. When all three batteries were hooked up to a hobby charger to check the actual mah story was even more telling-

DAV 1- 646mah (651mah on original test)
DAV 2- 623mah (650mah on original test)
DAV 3- 639mah (651mah on original test)

as always, thank you sir.

No problem Kyfatherof1 sir. Glad to be of service.

Time for an update everyone.

DAV 1. Never deep cycled, only used with slim line-

Average use time after 100 charges- 2 hours 47 minutes
Average use time after 150 Charges- 2 Hours 46 minutes

DAV 2. Always deep cycled, used with a fast charger never left unattended at my own risk-

Average use time after 150 charges- 2 hours 38 minutes
Average use time after 200 charges- 2 hours 33 minutes
Average use time after 250 charges- 2 Hours 7 minutes

DAV 3. Never deep cycled, only charged with a fast charger at my own risk-

Average use time after 150 charges- 2 Hours 42 minutes
Average use time after 200 charges- 2 Hours 41 minutes
Average use time after 250 charges- 2 Hours 38 minutes

Actual mah rating tests test

DAV 1- 645mah (Previously 646mah)
DAV 2- 553mah (Previously 623mah)
DAV 3- 636mah (Previously 639mah)

As we can see DAV 2 is reaching it's end of life, it's lost roughly 15% capacity at this point and knowing how batteries work won't be shocked if it doesn't make it to charge 300 before it needs to be recycled. Will update this either once DAV 2 dies or when 1 reaches charge 200.

Time for yet another update.

DAV 1. Never deep cycled, only used with slim line-

Average use time after 150 Charges- 2 Hours 46 minutes
Average use time after 175 Charges- 2 Hours 45 minutes
Average use time after 200 Charges- 2 Hours 45 minutes

DAV 2. Always deep cycled, used with a fast charger never left unattended at my own risk-

Average use time after 250 charges- 2 Hours 7 minutes
Average use time after 275 charges- 1 Hour 49 minutes

After charge number 287 the use time was only 1 hour and 14 minutes. Needless to say this battery has given up the ghost. Fast charging and deep cycling is a quick way to end the life of your DAV.

DAV 3. Never deep cycled, only charged with a fast charger at my own risk-

Average use time after 250 charges- 2 Hours 38 minutes
Average use time after 275 charges- 2 Hours 35 minutes
Average use time after 300 charges- 2 Hours 31 minutes

DAV 4. Deep cycled and used only with the USB charger from V4L-

Average use time after 5 charges (baseline)- 2 hours 49 minutes
Average use time after 50 charges- 2 hours 48 minutes

Actual mah rating tests test

DAV 1- 644mah (Previously 645mah)
DAV 2- 498mah after charge 275, final mah rating was 377mah (Previously 553mah)
DAV 3- 629mah (Previously 636mah)
DAV 4- 648mah (649mah on original test)

So ends the life of DAV 2. This (on top of other reasons) is a big reason why V4L hasn't brought a quick charger to market as of yet. Could technically recharge that DAV 3 times a day using it, and can almost guarantee based on past experiences with batts if I had put them strain on them the 287 charges would have been closer to 220 or so. Makes room for DAV 4 though.
