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).
- All circuitry is designed and manufactured in-house in the USA.
Any standard, voltage regulated 12V lead-acid charger will work. Do not use any special charging modes of your charger (ex: desulfation mode). If your charger has a setting for battery type, choose "AGM". Do not use a simple trickle charger as they may not stop charging once the battery is full, use a maintenance or float charger instead.
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.
In some rare installations, two or more batteries may be wired in series (for example, if your car has a 24V system, it may use two 12V batteries in series). Voltphreaks batteries are NOT compatible in this type of usage. Also, do not parallel a Voltphreaks battery with another battery.
* 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, 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 purchasing a Voltphreaks battery for 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 supplying power) first to insure compatibility. Voltage at idle should be around 14-14.6V. This likely only applies to Porsche GT's, as we have not encountered this issue with other cars including other Porsches.
