Replacement battery for Motorola TalkAbout radios

The Kastar M53615 is a 3.6 V Ni-MH pack rated at 1650 mAh and 5.94 Wh. It fits a long list of TalkAbout two-way radios including the EM1000, FV800, T4800, T4900 and T5000 series. The bundle adds an LTD2 dual USB charger so users can power a spare cell while the radio is in use.

Dual-slot charging with micro-USB and Type-C inputs

The LTD2 charger accepts 5 V at 2–3 A through either micro-USB or Type-C and can charge two batteries simultaneously. Each slot delivers 8.4 V or 4.2 V at 800 mA when used alone and shares the current when both slots are occupied. An intelligent LED display shows charging status and remaining capacity for each cell.

Ni-MH chemistry limits runtime compared to Li-ion

The pack uses nickel-metal-hydride chemistry at 3.6 V rather than lithium-ion, so energy density is lower and self-discharge is higher. Buyers who need the longest possible talk time per charge or the lightest pack for extended hikes should look for a lithium-ion alternative if their radio supports it.

Questions about this item

Does the LTD2 charger get hot or draw much power when it runs all day charging two batteries?

The charger takes 5V at 2-3A input and delivers 8.4V or 4.2V at 800mA per slot, so heat and power draw stay modest during continuous use.

What cable or power source do I need to run the LTD2 charger out of the box?

A Micro-USB cable is included; you only need any 5V USB supply such as a phone charger, power bank or PC port with 2-3A output.

Will this 1650mAh Ni-MH pack work in my older Motorola TalkAbout T4800 handset?

Yes — the battery replaces Motorola part numbers including 53615 and HKNN4002, which are listed as compatible with the T4800.
