Streamlight SL-20L NiMH Battery

Finally got around to upgrading the battery in my SL-20L, and the NiMH holds a charge noticeably longer than the old one. It recharges in about 40 minutes just like the specs say.

Swapped out the old battery in my SL-20L and this NiMH pack fits perfectly, giving me that full brightness without the weight of the original. It's held its charge well through a couple of night shifts so far.

Charging this pack took just under two hours, and it’s held its charge for weeks of daily use without any noticeable drop-off. The fit in the SL-20L is snug with no rattling, which is exactly what I wanted from a spare.
