- View SourceI just purchased Deka 8G34R (60Ahr) batteries for my EV conversion.

Unfortunately the technical literature is sparse in determining the proper

charger profile. Knowing that a lot of Force drivers use the Deka Gel

batteries, is it possible that someone can post their charge profile for

their Deka Gel batteries?

I have searched the archives, but did not find anything definitive.

It says the charge voltage is 13.70-14.10 V at 20 deg C (68 deg F). The

charge amperage is to be as high as possible up to 20% of the C/20 rate

(C/20 = 60Ah therefore the max charge amperage is 12 Amps.

So at 20 deg C (68 deg F), I will charge at 13.7 Volts per battery at 12

Amps

1. When is charging finished? When amps drop below a certain level? When

voltage drops?

2. When charging is finished, should I put it on a float voltage? It says

the float voltage to be 13.55 volts - but at how many amps?

thanks for the help.

There is a lot of info at www.mkbatteries.com You need

to look around their site a bit, but there is a technical

paper in .pdf format that describes the 3 - 4 step charging process.

I would send it to you, but my other computer is down right now.

PS: I believe the Zivan charger people know the charging profiles.

what the relationship between East Penn and MK are??). I found the

technical charging information on their web site (which is actually

www.mkbattery.com)

- thanks.

1) Bulk charge to 183.3 volts until charger amps drops to 3 amps.

2) Overcharge at 3 amps up to 195 volts maximum until overcharge AH amount equals 10% of Bulk charge AH total.

3) Float at 176. volts. Amps should be irrelevant because you are already fully charged and the batteries will only take a small amount to keep floating.

I have uploaded the charge profile from my NLG412B charger for 8G27

Deka batteries to the Files area of the Force_EV site.

Hope this helps,
