Drop in replacement for lead acid battery.

We only guarantee these packs to capacity test at their individually tested amp hour rating. A packs ability (or lack thereof) to hold a full charge is a reasonable indicator of it's remaining lifespan. Because of this lifespan consideration the packs are priced on a curve instead of a set amount per Ah capacity.

Item sent could have grey or black top versions as pictured, just depends on current stock.

IMPORTANT - PLEASE READ:
These packs self drain slowly due to the internal BMS and LED indicator.
If these packs sit for too long or are discharged too low they will go into a safety mode that requires them to be trickle charged before they can be used again.
