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.
Assorted tested capacities.
Item sent could have grey or black top versions as pictured, just depends on current stock.
The built in connection cables for series/parallel connections has been severed. This has no effect on the battery's functionality as a lead-acid replacement.
