DROP-IN REPLACEMENT

Voltphreaks batteries are a drop-in replacement for your lead-acid battery *. Once installed, you can forget about it, and treat it just like a standard car battery. Lithium batteries require management during charging and discharging and have different requirements compared to a lead-acid battery, but this is all handled behind the scenes by the internal circuitry every Voltphreaks battery. This circuitry masks the fact that it's a lithium battery, allowing the battery to be used and treated as if it's a lead-acid battery.

• Similar to an AGM battery, there is no need to vent the battery in normal operation.

• Battery can be installed in any orientation, even upside down.

• The circuitry in each Voltphreaks battery balances and maintains the cells for longest life and safest operation (some competitors do not use any circuit inside the battery, we do not recommend this as it greatly increases the chance of battery failure).

• Because of the built in management system, there is no need to manually balance the battery.

• All circuitry is designed and manufactured in the USA.

Any standard 12V lead-acid charger will work. Do not use any special charging modes of your charger (ex: desulfation mode). Float/maintainence type chargers can also be used.

For 16V batteries, only a Voltphreaks 16V charger should be used. In a pinch, you can use a standard 16V charger due to the built in over-charge protection in every Voltphreaks 16V battery, but this should be done only rarely.

* POSSIBLE IMCOMPATIBILITY

Lithium batteries could be incompatible with some (not all) Porsche GT cars. We have heard from some customers that their GT's alternator may not maintain the right voltage to charge a lithium battery. We are not aware of any other cars that show this behavior.

Almost all car alternators maintain 14V to 14.6V to properly charge the car's battery, and this is what the Voltphreaks battery expects. Some Porsche GT's undercharge their lead-acid batteries, and this is not compatible with the more efficient lithium batteries. Below 13V, a lead-acid battery will be partially charged, but a lithium battery will be barely charged. If you have a Porsche GT2 or GT3 (or if you suspect your car's voltage may be incompatible), measure the voltage with engine on (so alternator is active) first to insure compatibility. Voltage at idle should be around 14-14.6V.
