Will these fit my feeder lantern?

They match the common 6V 4.5Ah sealed lead-acid size at roughly 2.76 x 1.89 x 4.21 inches. Measure your old battery and check the terminal shape before ordering.

Are these rechargeable?

Yes. They are sealed lead-acid cells meant to be recharged, typically by the device's built-in charger or a 6V solar panel.

Can I use them in cold weather?

They work in the cold but lose usable capacity as temperatures drop. A feeder in freezing conditions will run shorter between charges than in summer.

Do all four batteries need to be used together?

No. They are separate 6V batteries, so you can use them in different devices or keep spares. Charge them fully before first use.

How do these compare with a lithium replacement?

Lithium packs are lighter and last more charge cycles, but cost more and may need a different charger. Lead-acid is the simpler drop-in choice for older 6V gear.
