Our take on the West Marine 24 Lithium Iron Phosphate Dual Purpose Battery

This is a Group 24 dual-purpose lithium iron phosphate battery rated at 60Ah and 12V, built to start an engine and run electronics on the same bank. LiFePO4 chemistry gives it a much longer cycle life and far less weight than a comparable lead-acid Group 24, and it holds voltage steadier as it drains. It suits boaters and van owners who want one battery for starting and house loads without the maintenance of flooded or AGM cells. The trade-offs are a higher upfront outlay than lead-acid and the need for a lithium-compatible charger and charging profile.

Pros
  • Dual-purpose design covers starting and house loads
  • LiFePO4 chemistry tolerates deep discharges better than lead-acid
  • Noticeably lighter than an equivalent Group 24 AGM or flooded battery
  • Group 24 footprint drops into many existing trays
  • Long claimed cycle life cuts replacement frequency
Cons
  • Costs more upfront than a comparable lead-acid battery
  • Needs a charger and alternator profile set for lithium
  • Cold-weather charging needs care; below-freezing charging can damage it
  • Built-in protection can shut the battery off under heavy load

Questions and answers

Can it really start an engine and run electronics at the same time?
Yes, that is the dual-purpose claim. It is rated for both cranking and deep cycling, so one Group 24 can serve a start bank and modest house loads. Check your engine's cranking current against the battery's discharge rating before relying on it alone.
Do I need a special charger?
Yes. Use a charger with a lithium or LiFePO4 profile, typically charging to about 14.4–14.6V and holding there. A standard lead-acid charger can leave it undercharged or push it too high.
Will it fit where my old Group 24 battery sat?
The Group 24 case size is the same standard footprint, so it usually drops into the same tray and hold-down. Confirm terminal orientation and height in your compartment, since posts can differ from your old battery.
How does it compare with an AGM battery of the same size?
It is lighter, tolerates deeper discharges and should last more cycles. AGM costs less and needs no charging changes. If your charging system is not lithium-ready, budget for that change.
Can I charge it in freezing weather?
Charging below freezing can damage LiFePO4 cells. Many batteries block charging when cold and resume once warmed. Do not charge a cold-soaked battery until it is above freezing.
What is in the box?
Typically just the battery itself. Terminal hardware and a charger are usually separate, so check what your setup already has before installing.
