Are new batteries compatible with older searchlights?

Yes! Peak Beam’s current MBP-1308 Series LiFePO4 Batteries can be used with all older Maxa Beam Searchlights. Just keep in mind that you’ll also need to purchase a LiFePO4-compatible charger and cord to use with the new battery. Your old battery charger and cord will not work with the new battery.*

MBP-1308 Series Batteries are available in a standard, no-frills housing (MBP-1308) or can be upgraded with a 5-level LED fuel gauge (MBP-1308-FG). The fuel gauge reports the battery’s state of charge and state of health and is located in one of the recessed slots on the top of the battery.

All LiFePO4 Batteries feature a 115 minute run time, 110 minute charge time, and more than 2,000 life cycles. LiFePO4 Batteries weigh 3.0 lbs. and do not develop a memory, meaning they can be recharged or topped off at any time.

Older, discontinued Maxa Beam Batteries include the MBP-1207 NiCad Battery, MBP-1307 Li-Ion Battery, and MBP-1310 10Ah LiFePO4 Battery. For information on using and charging older batteries, please see the Legacy Battery Systems guide available on the Downloads page.

Caution: Only use Maxa Beam batteries with your searchlight; using third party batteries may damage the searchlight and will void the product warranty.

*The only exception is if you own an old MBP-1310 10Ah LiFePO4 Battery. In this case, your existing charger and power cord WILL be compatible with a new MBP-1308 LiFePO4 Battery.
